25 gallon Fuel tank in a SWB?

[Slowguy]

So I'm pretty sure what you are saying. I didn't even thing about the side to side supports of the underside of the bed. I wonder if that flared part of the tank that protrudes upward (that the fill neck attaches to) will get in the way of any part of the bed? I was going to chop it and solder in straight up this afternoon but I don't think I'll have time now. Maybe tomorrow.

Anyway, does your tank have as much gap as mine between the underside of the frame rail and the flat seam that runs all the way around? It really doesn't matter I think as long as the tank is strapped securely from the lower straps pressing the tank upward into the upper bars we made. It just doesn't seem from your pics that the seam hangs down as far as mine? Maybe it's perspective I hope. Also, hopefully this thread helps others wondering the same things. Here are few more pics...and remember I just have it kinda hanging there until everything dry-fits perfectly.

I don't think anything around the fill neck will be a problem. It's more the very back side of the tank where the very last bed brace will be - to the rear of the fill neck - and the big hump where the fuel pump/sender unit is. That is right in the way of the second, from the rear, bed brace. Kind of like where your straight edge is in your last few pictures. That second brace is going to have to be trimmed quite a bit to get over that hump. However, if the tanks are kept to where the top of those "corrugations" sit level to, or slightly below, the frame rails, then I don't think the trimming will be significant. Those braces are about 3 to 3 1/2 inches if I recall so that should be ok.

Yes, that seam where the two tank halves are joined hangs down quite a bit below the bottom of the frame rail - about like yours. By the way, those two areas on each side of the tank flange that looks like the flange is bent are where the two bottom braces should go. I will say, with mine bolted in, it's not going to go anywhere. The two bottom braces hold it real solidly from moving side to side and the top and bottom braces located in those "low" areas locks it in front to back.

Obviously, the tank will work. Jessemthompson, member on this site, has already done it. We just need to get the details figured out. We'll get there!
