this is what will be going into the back frame of the crewcab 40 gal cap

 

what did that come out of......looks pretty stout.

 

it's out of a 92 dodge just wish I knew who made it because Stout is putting it mildly it must weigh 75 lb's or better

 

looks like you can fill from both sides of the truck, ive done a few like that, using a cross pipe, you can fill both tanks from either side

 

Yes at 1 time it was set up that way but the nice part is the filler neck is made to mount to the wall on inside of bed kinda neat how they did it but what I am going to do is mount a fuel door on out side like factory tank
