Filler neck question

[xXxSilveradoxXx]

I'm finishing up my work truck swap and I have a question. Since I'm using a Tahoe/Blazer tank that mounts where the spare tire usually goes I have to fab up a custom filler neck. I think the filler neck that I'm making will work but I'm pretty nervous that It won't for some reason. What do you all think?
I don't have a pipe bender so I have to angle cut then weld up. Doing it this way is probably better since there needs to be some pretty sharp turns.











Here is a picture of the side of the truck to give you an idea of how much higher the filler is compared to the frame. I know the back of my cab is sagging pretty low, I don't have the rear cab mounts welded onto the frame yet.



So, what do you guys think?

I think with fuel having to flow uphill you will have a helluva time at the gas pump.
Relocate the fuel door to the back of the bed or put a hinge on the tail light and have it inside there.

I was thinking the same thing, but, I would think with the filler nozzle higher than the highest part of the pipe fuel would still flow to the tank. However, like you said, the question is usability.

It may work, but having dealt with a lot of duallies with service, flat or western hauler beds....some of them are a total pain in the ass to add fuel to. Even a small amount of back pressure will make the pump kick off and even worse if it doesn't you get fuel shooting out the side of the filler.
Maybe you could take your setup there before you put it on the tank and do some flow testing with a water hose.

even if it DOES go in tank (which i doubt) that pipe is going to constantly be full with fuel. I would put a flap door in the bed, that way it would be an almost straight shot. You could just drop the tailgate to fill up. The taillight idea would probably work, but I can see you running into a lot of problems with that, mainly with them moving while driving and more water getting on the wires/bulbs.

Seems pretty nice at first glance. But I think I have to agree with the others with that uphill which probably make the pump work harder than ever. So I also think that it's best to test how the flow of gas would run on it by using water. Anyway, that's just my opinion. Hope that would still work. Good luck!

Just some advice. Check the date on some of the threads before you post...
