rear tank

when i switch over to my rear tank it wont rev up all the way and it only does this after the truck sits for awhile. it was running fine sunday and i havent started it since and when i flip it to the rear tank it wants to bogg down and then it finally will run but if i floor it it runs really ruff and what rev up, as i hold my foot on the pedal and switch to the frt tank it revs up and the truck runs fine...also when i turn the rear tank is leaking some where and i cant seee where and its a new tank and it only does this when i turn left

could be a fuel pump problem. Try hooking up a fuel pressure regulator and make sure that you are getting full pressure. Could be a clogged fuel filter, but I believe both tanks feed into the same fuel filter. I would change the filter first because it is the cheapest fix. You might have a weaker rear pump that can't deliver well through the filter, but if the filter is replaced, the problem will go away. If you do the filter yourself you need a special tool. I recommend against the plier like tool that is shaped like an X and recommend the plastic/metal round inserts.

I had this after I replaced the tank, replaced the pump and the problem got worse. Took me several inspections to realize that I had kinked the fuel hose coming out of the pump.
