I am getting tired of gas @ $3.10 a gallon running down the bedside of my 74 and was wondering a couple of things:

1) Has any one figured out an easy fix for this? I looked and it doesn't seem like there is room to move or modify the fillers.

2) What Ford did in the later trucks with filler doors if anything.

I seem to have the most problems with the rear of my 2 tanks, any advice is apreciated as right now it takes like 1/2 an hour to fill my truck holding the nosle at "just the right angle" at half a click on the nosle.

Thanks

 

Many times the bed mounts have rusted away and have crimped the hose. Bed repair is the option then.

 

I have the sams slow fill problem with my 67 bronco with dual tanks. When I removed the rear tank a couple of years ago to repair some trail damage, I replaced all the filler hoses and the breather/vent hose. Now it works perfectly and I can fill it at normal speed with no burps of fuel all over the side of the truck. I would recommend simply replacing the rubber part of the vent hose and making sure the rest of the vent is unplugged, and if necessary replace the rubber fill hose, although they are much more expensive.

 

I replaced my tank, hoses and vent line some time back. I still cannot run a pump on full, but its better than it was. I just have resigned myself to only use the two stations around here that seem to run less pressure, holding the nozzle just right, and patience.

 

Have you figured out that certain gas-handles have "pipes" that are bent near the center and some are bent near the "handle"? And that makes a big difference?

The ones with the old-style "bent in the center" type are the ones to use.

Drive through looking at the handle-pipes and drive right on out... if they got them sorry new-style "straight" pipes on the pump handles. BTDT

After a while you know where to go. One outfit years ago when the new "straight" type pipes first came out I went in and complained and the kid behind the counter just happened to be very interested and came out to see what was going on. He happened to be related to the owner/managment and actually did something about it. Seems like they made a point of not ordering the new "straight" piped type anymore.

I did several things to my gas tanks in a sort-of shotgun-effect trying to make mine work better, but none were "easy". (well, other than the fact I already had the bed off

That was back when you could still get parts at the dealership tho. I bought some very expensive new filler pipe hoses. They were bundled together in pairs and had words and arrows on them for which way they were supposed to go on.

The originals on my '75 F150 were upside down and backwards!
Came that way from the factory, no kidding.
(a joke on me? the installer didn't care and/or just plain stupid?)

So that was one measly little thing that helped, but there were several others when added together improved things on my rear tank.

How much work and expense you willing to do?

I was having the same trouble you are and still do, a little.

My main problem was the heat and how the truck was sitting... the vapor pressure would shove gasoline right out of the full rear tank on a hot day and leave only 3/4 tank. So back in those days I made a point of not filling more than 3/4 full unless i was going to use it down that far before parking it in the heat.

Someone started a thread asking if I was in love with my pickup.
(I didn't respond

So just yesterday I'm filling my tanks and it's been so long since I bought gas for the sucker (with the ring and pinion problems and all) I forgot, and got stuck filling my rear tank with one of the new crappy handles with the "straight" handle pipe. It worked ok with some fiddling around.

Anyway, so I'm looking at the sucker and thinking how great it'd work if the filler cap was high-up on the bed, high like the "cab tank" filler caps are.

You could fill those by pouring gas out of a gas can (with no funnel or pipe) and not spill a drop. BTDT in the old days.

I second that.... I removed the tank behind the seat ( That I ALWAYS USED )and welded up the hole, just so that I could run a sub box... that I STILL havent finished buiding yet.
Swapped out the rear for a 38 gal, and then the "filling fun" became more of its own little nightmare......

 

Thanks for all the advice I am not against spending money to fix the problem, I have plans for a pearl paint job and i really don't want to ruin it. So if there is something like putting in the doors and fillers off a later model I could do it when I do the rest of the body work I just didn't know if it was possible it sure doesn't look like there is a whole lot of room between the bed-side and the frame to modify the filler tubes.

 

Heck if you can weld-up and finish off the cab hole, you can put a filler cap up high on the bed. :) "Custom" for real, not just off-the-self aftermarket parts added-on "custom"! :)

What about the newer models with the doors on them?
Do they fill easy? Just easier? No difference, still a pain? ;)

That's not good news to hear the 38 gallon tank isn't a solution to the filling problem. :/

Mine doesn't give me too much trouble after I replaced the hoses and bent the sheet-metal-hanger attatched to the bed... from an L to an \_ shape giving the lower part of the filler pipe a little more height. Wrapping a split can around the hose so it can be as round as possible (using screw-type hose clamps to make that work).

I made a modification to the tank too but after hearing the 38 gallon tank didn't help with the filling problem those modifications prob'ly made no difference. When looking into your new 38 gallon tank did the tank's filler pipe stop just inside the tank or go all the way to the bottom (like the stock tank does)?

My tank modifications were mostly for my problem with the AZ sun and fuel spewing past the filler cap, when the tank was full. Something I did, fixed that at least. :)

But -none- of the modifications I've come up with compare with the results from only pumping gas from the older style -bent in the middle type gas pump handle pipe-!

So far nobody's said "Yeah I knowed that already :)"

So is the "bent in the middle gas pump handle pipe only" an old idea everyone already knew or what? :)

replace the bushings under your box if they look like they may have settled. it may be the inch of difference your looking for.

 

Cool idea if that's the case.

My '75 F150 didn't come with any sort washers or bushings or anything between the bed support beams and the frame. No kidding.

I contact-cemented some aftermarket-type automotive-carpet (felt-like stuff) in place when I took my bed off. Just to quiet any squeeks, if there were any. :) I got more than $300 of SuperDynaMat in my cab too, BTW. :)

In my case If I raised my bed, I'd have to also raise the cab the same amount.

Something else about the fuel pump situation I forgot about... I park at the ones where the pickup is leaning toward the right. Man, that makes a big difference especially if coupled with a the sorry-new-style "straight in the middle" type pump-handle-pipes.

Couple both problems together and that's when my credit card company sees a less-than $2 charge form a service station.
