Fuel Tank Advice

Hey all, i wanted to get an honest opinion from you guys since i have searched and have not been able to find what i am looking for. I have my 68' F250 CS with the dual tank setup and am thinking about replacing both. I emailed spectrapremium but they couldn't help. Is there a good quality replacement tank or is the ones sold on LMC good enough ?? I have bought stuff from them and am not pleased about quality of products. Stock dimensions of tanks of course but do any provide thicker materials or will cheap ones be just fine ?? Steel or Plastic ones ?? The original main tank still works but aux stopped working before i got a hold of truck. Behind the seat doesn't bother me cause if Ford engineered it then that is good enough for me but its better than driving a chebby with the outside saddle tanks. You guys are awesome, thanks for any info you can provide.

I have not used the in cab tank but I have used the aux tank and it is a good product.

You are correct that many LMC parts are not that great (I think the rubber seals are the worst I've seen), but the gas tank I got is just fine. I think they are probably the only supplier for the factory style aux tank.

Don't forget to also get the rubber seals/hoses at the same time for the install.

Several years ago (when my truck was still a basket case), I had both tanks dropped and boiled out. One of them survived and I had it lined with plastic. The other was replaced.

Not sure which is which any more.

Had it done at a radiator shop.

Unless you're looking for a stock set up, you can get a fuel cell from Summit. It's a bullet-proof solution and could be mounted creatively in the bed or maybe even in the Aux tank location...

I priced American Radiator in Pasco and the cost to do-what-they-do to it was more than buying a new tank. I thought there was a radiator shop by Bonnie & Clydes on E *** Hill & 1st but I'm probably wrong. Been awhile since I was in Yakima. There was a guy in Yakima that sold ford parts on Craigslist but????
Maybe pull the tank and at least check it out. It might clean up just fine.

If you go shopping, keep in mind there's several different tanks for behind the seat. I have seen at least 3-4 different variations from 65-76. Not sure if each would exchange? Even the body mounted brackets under the tank can be different.

In stock form, all of the behind the seat gas tanks start to leak eventually for all they were was 2 pieces of molded sheet metal welded together with a vertical seem that SCREEEEAMED to leak. But there's a lot of gas tank products that fix them right up as long as your pickup is in good shape. I pulled all my tanks and restored them all at once for one of the gallon kits will do up to 3-4 tanks. But you need to read up for I found out how easy it was to screw one up trying to fix it. It's been too long ago and I don't recall all the specifics.

1961/69: The in-cab fuel tank was 18 gallons.

In 1970, Ford replaced the 18 gallon in-cab tank with the 1970 (1970/72 F100/750) in-cab tank that contained 19.5 gallons for use as a "service part replacement."

D0TZ-9002-A (replaced C1TZ-9002-K) .. 19.5 Gallon In-Cab Fuel Tank / Reproduced by Blue Oval Truck Parts (Anaheim CA), available from all the repro parts sellers.

Applications: 1961/66 F100/800; 1963/69 N/NT500/750; 1967/72 F100/750.

1973/77 In-Cab fuel tanks are different.

For the Aux tank the spectrapremium model F27F is what fit my 69 F250 CS. The ONLY small difference was the vent tube was straight instand of a 45 deg . But the original hoses fit on that perfect anyways.

I have a really nice inside tank from my '67. Only problem is getting it shipped 3000 miles away. Free to good home.

I just purchased and installed one from LMC into my 69 f100 and fit very good. If you get one from them be sure and get the hose that connect the filler tube and the tank together because the old one is going the to be very hard. I even purchased the rubber that goes around the filler neck outside.

If you don’t mind me asking what is the cause of the auxiliary tank not working? Is it rotted or just no fuel getting to the engine? I couldn’t fill mine as the fill hose was dry rotted. Pulled the tank, what a pain in the ****, and it was pristine inside! About a gallon of some iced tea looking varnish in it, but zero rust! Bought the LMC hose kit, repainted the armor plating (yeah that think is probably second in thickness only to the frame) and brackets then reinstalled. Also tested, adjusted, replaced the float and used the original sending unit. Just curious what the source of the problem is.

In my case I did not have a tank. The filler tube/neck was there (it had one from the factory) but a previous owner took it out.

The tank is a pain to install. You have to get the fill tube hoses through the frame and at the same time have the driveline out so you can get it all the way "up and over", while also attaching the two straps hardware.

If I have a professional garage, you could have the truck up in the air and make it a two person job and have one hold the tank while the other attaches, connects, etc.

JEFFFAFA - I'm not defending LMC - I'm still angry about all the door/window seals I got being so crappy, but the fuel tank is good. They deserve credit where credit is due.

grantorinosport, actually you do not need to remove the driveline to replace or install the auxiliary tank. I took mine out and re-installed it without dropping the driveline. It takes some correct angling, but it goes in and out without doing so. I did it by myself in the driveway while it was on the ground albeit I used a quad/atv lift to hold the shield up while I attached the bracketry when putting it back in place.

Thanks everyone for taking the time to respond to my post. I am learning that when it comes to these older trucks that dealer quality parts are often hard to find but market seems to be flooded with aftermarket stuff. Lots of credit goes to the men and women who have dedicated their lives to keeping the older ones running. Personally i am not interested in a brand new shiny truck since the older ones to me just have more character so new ones have too many fancy gadgets that might fail at some point. But to each their own, mine is old but i will never have to worry about it being repossessed in the middle of the night. Health issues seems to limit how much i want to get done on my truck but my mind is always thinking of something to upgrade so yes a man with an older truck and a credit card can be a dangerous thing. Actually got a ticket last month when i decided to do a couple of donuts for my import loving son and of course a cop was there to see the whole thing. But oh well, had to show my son that american muscle is still where its at. I might not be able to leave town cause of gas mileage but racing imports in-town is a lot of fun just have to keep an eye on the gas gauge.
