I've got a flatbed on my truck, and the PO ran the rear fuel filler up through the bed. I've broken the cap off once doing firewood, and now have an improvised wooden guard in place to protect it, but the whole setup is FUBAR.

I was going to just cut a length of pipe off of my donor truck, and use hose clamps to add it as an extender in the flex section, but realized there's an outer and inner fuel hose. What's the best way to go about lengthening, or maybe straightening the filler hose/pipe to mount it to the bottom edge of the flatbed's outer rail? I'm sure someone else has had this issue before. I know at least a few of you insist on working your F-trucks.

It's my '95 F-150.

 

When I put my flatbed on my 93, I mounted the fillers under neath the bed rail. I found out the first time I tried to get gas that it wouldn't work, without driving up on a block of wood. I did this for a few years, til I got around to fixing the problem. There wasn't enough angle in the fillers to let gas run down into the tank without backing up and shut off the nozzle. I ended up cutting new holes in the bed rail and mounting the fillers where they work properly. the front one was easy, just had to loosen the hose clamp on the tank and twist the hose around til if reached t he hole. The rear one, I had to extend. I did this by cutting the hose in the straightest part and put a lenght of stainless steel muffler tube in there with hose clamps. I didn't worry about the inner hose, and it has worked properly.

 

Is the inner hose attached to anything inside, or does it just hang into the tank?

 

It just hangs inside. That's why I didn't worry about extending it too.

 

I tried extending mine on the rear and all it did was move the neck farther out, I still couldn't get gas in it. I looked at a friends dump and it seemed that because the bed was on top of the left arms and brackets that raised the angle enough to let gas flow downhill into the tank. So it seemed to me the bed has to be higher or more angle on the filer neck.

 

I've seen flatbed and dump bed F-series trucks that have almost straight necks on them, but running up like a ramp. I presume that some companies out there make something for exactly this purpose. I'm just looking to imitate them.

I only need about three-four inches or so, but I don't want to cut into it and shoot myself in the foot.

 

I'm going to dive into it now, just have to make sure I've got a piece of pipe the right length.

 

Thats what did.

 

Thanks, 2fords...







I still plan on making a more permanent mounting to protect it from brush when I use the truck in the woods, but for now I'll add this to my list of uses for old innertube strips and electrical tape.

 

Well glad I could help. do you plan on Cutting a hole in the side rail to mount it?

 

I was thinking of just drilling two holes and using a U-bolt to make a guard/mount for it.

 

This is an old thread, but I'm having much the same problem. My 1985 f350 flatbed diesel has two tanks, and the fuel filler pipe/cap locations suck! They not only lay nearly flat, which makes filling the tanks a serious pain, they are in the way of the walls I need to build on the frame of my flatbed. I want to place the mounts up on the new walls so there's more angle to the lines, and to keep from having to build around their current location. Any help with what I need?

 

I used this stuff on my cars fuel cell filler neck,works great. The way mine is routed, fuel stays in the hose and it does not leak.

 

So I just use this hose and re-route the inlet where I want it? How do you know what diameter hose to use? I've googled and just can't find what size I should buy.
Thanks for your answer, by the way

 

Ended up needed to take my Beast to my mechanic for another reason, so figured out all I needed to make my modification. This thread was a help though. Thanks
