Well, like I said, I don't fill my tank right up to the top and I might even do that little mod I just mentioned to Lattimer.

I am not changing the tank to a newer in-cab one just for this. When I go shortbed, all this crap is coming out of the cab and going out back anyway. I'll likely get an EFI ready tank with a submerged pump too to get rid of the command center and the clutter it adds under the hood.
