Re: Fuel tank under bed

IMHO they all look terrible. Installing a tank in from the bottom isn't that difficult. Accommodating the fill was my issue.
I wished I would have looked into the Camaro tank closer. Relocating the tank has been a giant pain and the costs have added up. Some of the cost overruns were my fault as I purchased the hardware to install the fill behind the tail light which I didn't use among other ideas I abandoned.

I used an aftermarket Aluminum Tank.
It was made in China poorly designed. It hit the bed cross-member before the flanges on the side came up against the frame. The pump was on the wrong side of the cross-member so fuel lines and electrical would have to go through the bed cross-member and the fill was too far forward to reach comfortably. I have made a lot of changes on my truck and relocating the tank was by far the most difficult. I made it work but it delayed my project. Figuring out a fill, that was tolerable, was a longer process than I would have liked. I ended up reversing a Blazer fill and mounting it on the inside of the bed. I had to plug the old tank fill and weld in a new bung for the revised filler location. I also added a electric fuel pump and rotated the tank 180 degrees so it would all work. I also had to build an adapter to go from the 1-3/4" to 1/-1/2" on the fill tube. And I changed the angle on the Blazer fill so it would work.
So You can see why prior planning is so important. I recommend you take a close look at the Camaro tank. The early Chevelles also have the fill behind the plate and this part is available after-market so it's easy enough to find.

I have included a picture of the unpainted fuel fill I ended up with along with the modified fill tube.
Thanks for your thoughts and recommendations. Awesome info.
I will look into the Camaro tank.
