Hi,
Just bought a 90 F150 2WD (302 Fuel Inj) that has two fuel tanks & when I switch to the front tank the engine dies. Been searching this forum for a while & found post = https://www.ford-trucks.com/forums/1...nk-switch.html which has a great deal of info & seems to be pointing towards either a bad in-tank pump, dual function reservoir or a check valve in one of the fuel pumps (possibly bad gas too - don't know how long the gas has been in there). Have replaced the selector switch in the dash - no help.
Also found another post on another web-site, don't know if it's OK to mention another site here but found it interesting that subford was in both = http://www.fordf150.net/forums/viewtopic.php?t=70701.

Began to exihibit information overload & am somewhat of a novice when it comes to other than simple repairs but want to work on this truck myself. So before I tear into this gas tank can someone tel me if I'm heading in the right direction? Sounds like replacing the fuel tank selector valve would be an easy fix before dropping the tank? What is the FDM (Fuel Delivery Module-is that the pump?) & should I replace the check valve if the tank is removed?
Also is there a repository for F150 fixit stuff I can easily find that has repair instructions e.g. removing gas tank/replacing in-tank fuel pump. Guess I could get a Chilton's unless there's something better?
