I was reading a post on here a while back that told what gas tanks would fit a 48-52 F1 trucks. When I lost my bookmarks I lost it anyone know where to find it. Thanks

 

Seems to me I recall that most are using a mustang tank oe custom built tank in the 48-52 trucks. If yu do a search there are a ton of threads that will come up.

You could also check on this site if you know what dimensions you need you should be able to match one up. Prices seem real reasonable.

Rusty,
I don't have my link to the fuel tank article handy (I can never remember where I saved it either). Its a great article by Fergie and lists alot of different options and the pros and cons of each. Hopefully Randy Jack will post it (He's usually really good at remembering that sort of thing)

You will need to consider what type of gauges you are going to be using when thinking about a gas tank. Also where you want your fuel neck.
I used a full sixed GM Blazer tank, they come in 2 sizes 24 and 30+ gallons. I use the 30 (it was a freebie) The fuel filler is in the top of the tank and points towards the passenger side. (I have pics in one of my galleries) I used a marine style filler neck in the top of the right rear fender.
Randy Jack use a full sized Ford Bronco tank in his 56. Check out his gallery, he's has an impressive right up about it. The fuel filler neck oints towards the dirvers side and he notched the frame for acces. check out the gallery, its amazing.
I think Fergie is running a full sized GM Van tank inhis truck, very similar to the fulls sized Blazer tank
The mustank tank is also a great option, jnoilon has a great article on the installation of this set up. The fuel neck comes up in the bed of the truck though (thats why I didn't like it...that and the fact that I got a blazer tank for free)

I've also heard rumors about Jeep fuel tanks as well as Mistubishi Montero tanks but I don't know much about either of those.

I'll search a bit and see if I can find the article on tanks

Bobby

 

So far here's what I found, which I don't think it made tech article, but thanks to Fergie anyway:

Tons of choices, here's a recap from our FAQ article (yet to be posted);

1948-1952 Trucks
The mid-1980s Chevy Blazer tank works well in this case and comes in both 24 U.S. gallon and 31 U.S. gallon capacities. At least one member of this FTE 1948-1960 Forum has successfully used this tank setup.
Another alternative is the 1970 Mustang tank with a 22 U.S. gallon capacity. Apparently, the earlier Mustang tanks discussed below will work on the 1948-1952 F-1/F-100s as well. Since the distance between the frame rails is nearly identical, anything that fits the 1953-1956 models should also fit the 1948-1952 models.
If you want a larger tank, the 1980 through 1986 (and possibly through 1989) full sized Ford Bronco tank is worth looking at. At 33 U.S. gallons capacity, it measures 31.875” long x 22.25” wide x 15.75” deep in steel, and slightly smaller in the polymer version.
Other tanks which have been used, but for which we have little info are from the 1980s GM Suburban and 1984-1985 Isuzu Trooper.
1953-1956 Trucks
Stock replacement tanks for the original locations are available in polymer or stainless steel from Tanks Inc. and several other sources – but since they are limited production they tend to be expensive.
No discussion of suitable fuel tank alternatives for this range of years would be complete without highlighting the early Ford Mustang tank (1965-1970). Forum member John Niolon has thoroughly documented this tank as a replacement in an article at http://www.clubfte.com/users/jniolo...mustangtank.htm (his web site has many other useful articles as well). The Mustang tank comes in three different capacities and all are easily obtained through www.gastanks.com or many Mustang oriented aftermarket suppliers. Another plus with this tank is that the Mustang sending unit will work fine with the stock 12v fuel gauge. A few minor nits however include 1) the inlet for filling the tank comes out the top at the rear, forcing you to bring it up through the bed 2) the filler pipe is approximately 0.75 inch off center towards the passenger side and 3) you may have to grind about a 0.5 inch off the bottom edge of your frame rails to fit the tank – although this is not a big deal. A lot of people have used this alternative, possibly more than any other single alternative.

Mustang Fuel Tank Installation


Yet another tank option is the full sized Chevy Van 1987-1995 fuel tank. It’s available in two different capacities – #GM8C (Spectra Premium Industries) has a 22 U.S. gallon capacity and a second version has a 33 U.S. gallon capacity. The difference between the two is the depth. The length and width are the same for both tanks. If you’re running fuel injection, you should be aware of the different system pressures that Ford and GM use. To avoid having to deal with this issue, with Ford engines use the non-EFI sending unit (#FG17A) and use an inline fuel pump. The 1990 Ford Ranger works well in this application. If you are running a GM power plant with EFI, then go the other way and use the EFI sending unit (#FG17B) which employs an in tank fuel pump and sending unit.


1987-1995 Full-Size Chevy Van Fuel Tank Installation
The 1977-1981 Chevy Van tank was offered in both 22 U.S. gallon capacity and a larger size as well. One of our FTE forum members (Tacson, AKA Donald Walker) has some excellent photos in his gallery which clearly show how well it fit and how he mounted it. The only difference between the newer tank used by Ferguson and the older model used by Walker is that the newer tank has the filler diagonally opposite the older tank. Walker used a slightly different mounting method – although both installations employed the original mounting straps for the tank.

1977-1981 Full-Size Chevy Van Fuel Tank Installation

Neither of the full-size Chevy van installations discussed above requires any cutting of the frame rails. However, both installations did require routing the filler tube through the frame rails.
The alternatives already listed provide ample, easily adapted, decent sized tanks. If you don’t mind admitting to using less cool sounding donors, then consider the following.
· The 1996-1999 Isuzu Trooper fuel tank – capacity unknown. There is a question about the availability of new sending units for this tank. However, at least one member of this forum has used it and there is an installation “how to” article in the June 1996 issue of Custom Classic Trucks.
· According to a few of our forum members, the 1961-1966 Ford Econoline Van tank is virtually identical to the early Mustang fuel tank – but the filler tube is on the driver’s side.
· Going back in time a little further, the 1957-1958 Ford passenger car fuel tank (Ford part# B7A9002B or www.gastanks.com part# F-34B) fits easily between the rails, holds 20 U.S. gallons, has a driver’s side filler, and can be purchased for about $200.
· Apparently the 1970 through 1977 Mavericks and Comets are similar to the Mustang tanks but the filler runs out the back.
· If you want to put the tank inside the frame and under the cab like the stock panel truck mounting location, an 1984 Ford Ranger supposedly works.
1957-1960 Trucks
Given the similarity in width of the rear frame rails for the 1957-1960 and 1948-1956 model years, anything listed for the earlier trucks should fit the 1957-1960 model years. Be aware, however, that no information on actual installations in the later year trucks is available at this time.
Classic Performance Products (www.classicperform.com) offers a tank that will fit under the bed of the 1957-1960 trucks. Again, since this is a limited production item, the cost is higher than a used tank would be. An alternative is an NOS 18 U.S. gallon tank, Ford part # COTB 9002-B available through Green Sales in Cincinnati, Ohio.
Fuel Tank Senders and Gages
A final consideration when using a newer or donor tank is compatibility of the sending unit with whatever gauges you plan to use. You may need to modify either the fuel sender or the fuel gage so that they have matching resistance characteristics. This can end up causing more grief than mounting the tank itself. The following information comes mainly from Autometer (www.autometer.com) and addresses the electrical characteristics of the OEM sending units.

Type of Sender/Gage Reading Empty (Ohms) Reading Full (Ohms)
Most pre-1965 GM 0 30
Some GM trucks through 1968 0 30
Most 1965 and later GM 0 90
Most pre-1987 Fords and most Mopar 16 158
Ford pre-1987 bi-metallic gauges 10 70
Ford 1987 and later F-series trucks magnetic gauges15 160
Note: Ford Motorsport gauges made by Autometer require the Autometer sending unit # 3262 which operates at 240 ohms empty and 33 ohms full unlike the normal Ford compatible senders as detailed above.

i'm using a gas tank with skidplate from an 89 Jeep Wrangler that came with a 4-cylinder. (the straight-6's are wider) I removed both rear crossmembers and relocated, also flipped one upside down.

 

My FAQ will never be published on this site as a tech article.

 

I'm gonna be using a 93 F-350 chassis cab 18 gallon poly tank in my truck.

It can work for carbed and fuel injection since they used this tank from 1980 to 1996.

 

Thanks fellas; I got a pretty good idea of what to look for now.

 

Here are a few more examples.

I read thru the posts on this thread and there is limited discussion bringing the filler neck to the outside of the body/fenders /bed. I have been planning to use my stock tank (it is in good condition and I am running carburated). I don't want the filler in the bed and am not planning any significant sheet metal changes to my 49. I would like to get the tank out of the cab and increase the capacity somewhat. I am setting willard up with a class 3 or 4 hitch to tow a car trailer so I need to plan for that. Anyone been down this road? Got any pix?

 

My original plan was to morph in a fuel filler door from a newer vehicle. After looking at it I took an easy out and used a marine style filler neck. I had to poke a 1 3/4" hole in my fender to mount it though. My filler neck is in the upper rear of my 49' passenger rear fender.

Take a look at Randy Jack's install, he did a fantastic job of putting fuel filler door in his truck. I have also contemplated using one of those pop up fillers that are used on custom motorcycle tanks. Take a look at ferguson777's gallery, I think he used that style on his VERY custom bed.

I will also be installing reciever hitch on my 49 but I don't see how it would interfere with the fuel tank or filler neck in any way

Bobby

 

I plan on a class 3 hitch also. Your F1 should be pretty close to my 56 for the same mods. There is plenty of room behind the Bronco tank for the hitch installation. This pic is a good look at the room left for the hitch: https://www.ford-trucks.com/user_gal...127103&width=2

I tried to show the relationship between filler neck and tank install here:

Tank install: https://www.ford-trucks.com/user_gal...&albumid=24084

Filler neck and gas door install: https://www.ford-trucks.com/user_gal...&albumid=23987

Basically, I built my system from the inside out by installing the tank first, then finding a filler that would work.

Good luck. Take pics and do a gallery for the next guy with the same questions.

 

RJ thanks for the info! I think that you are correct, I could do a similar tank and fuel door on my 49. Have you done a fitup with the bed on? For my bed it looks like I would have to modify the skirt that extends below the bed floor for the exiting fill line unless I mounted the bed higher above the frame. Is that what you have done or need to do also?

 

Yes, I have had the bed on the truck. My fill line goes behind the tire, but in front of the rear edge of the bed wall cutout, so the fill tube is a straight line (slight down angle) between door and tank filler. I didn't have to cut any of the bed to line it up. In fact, the fill tube is just to the rear of the third bed floor support rail, which runs over the top of the tank.

Basically, the fill line lays on top of the frame rail and just below the bed floor. The fill line being 1-1/4" dia makes that fit real easy, since the clearance between bed floor and frame rail is about 2".

I'm not familiar enough with the F1 bed to know about your "skirt", but I am assuming that the F1 and F100 are similar there.

 

49willard,

I had to modify the apron you are talking about on my install. On my 49 it seems like there was approx 2" between the bed floor and the top of the frame but the bedside (or apron) does extend down below the bedfloor. I radiused a small section of the apron where my filler neck exited over the frame rail.
I have a rubber hose connecting to the tank that goes between the frame and the bed, this connects to a 1 1/4" PVC electrical sweep (from the local hardware store) to make a 90 degree transition up to my filler neck.
