As part of my s10 frame swap, I relocated the gas tank to under the bed/behind the rear axle. Iv seen trucks where they put the filler right in the bed floor, I'm not fan of that. What I'd like to do is put it in the rear fender, preferable in the rear of the fender. Has anyone done this? Have pics for ideas? I dont know yet if i want try and add a hinged door with filler neck behind it or just come out with filler neck like how it is on the cab. Any thoughts or resources on materials?

Thanks
