The selected pump must actually be pumping fuel in order for the switching valve to operate.

I have a 1991 F-150 4.9L inline 6 cyl., and the front tank was leaking so the shop removed it and put a fuel filter inline somewher in a return vapor line (?), and now it is hard to start and once running seems to run ok. Where can I get instructions on what fuel lines need plugging, routing, t-connect, or clamping if the front tank is permanently removed? Will anything else go wrong other than hard starting, such as too high fuel pressure, incorrect vapor return pressure or routing, etc. etc.?? Call me at 410--903---2759 or rcbartel@yahoo.com

I have a 1990 model and I removed the rear tank all I did was joined up the hoses and taped up the wiring and it runs fine... It was no problem at all. The switch in the dash is still connected as it was before if I switch it to the rear tank the engine stalls after a few seconds. It was a simple job...
