I recently replaced most of my fuel system. The injection pump had been failing (no hot starts unless you have a cold damp rag to cool it), and I decided to replace the injectors and lift pump, as well as fuel filter o-ring(was leaking). A few months ago I took off the bed and replace my broken-off tank pickups with diesel rated hose. Well, after replacing the fuel system, I could not get fuel to the injection pump. I could refill the filter and it would run off of that until it died. I just about killed 2 batteries trying to purge air from the lines. At that point, I didn't know if I had a problem at the lift pump, or further back, but I stumbled accross the carrier pump thread and decided to buy one (I'd wanted to go electric for a while.) Got the pump plumbed(3/8" fuel line from the fsv) and wired up, and it works fine, except I still have no fuel to the pump. I let it pump for about 2 minutes, fiddling with the tank selector switch in the cab, meanwhile, the fuel selector valve got very hot. Not wanting to damage the new pump, I turned the key off, and here we are. Hot FSV, no clicking when I switch between tanks, the fuse is intact, and the valve made a clicking sound but still got hot when I initially tried to purge the air(with the mechanical lift pump.) I've got a feeling the Fuel selector valve is bad, or became plugged, or something, but I wanted to get some more opinions on this. If it is the fuel selector valve, does anyone have an updated part number? I got E7TB-9F271-AA, but it appears to be obsolete. Thanks, Peter A.
