I've got some bad gas. (the truck that is) Truck is a 89 F150 4.9 I want to use the fuel pump to pump out the tank. I don't work on gassers much anymore but I remember there was a jumper wire that could be used to turn on the fuel pump. You jumped two terminals in the diagnostic plug in the engine compartment I believe. Does anybody know which two terminals to jump? Thanks.

 

i manage a gas station locally and if you know the place you bought it from, they will pay to have your gas sucked out for you and a fresh tank for free. If it wasnt due to a gas station, then i think it might be easier to just drop the tank? i could be wrong tho

 

The gas went bad due to it sitting around too long. There is only about 3-4 gallons.

 

imo i would just fill up the tank with fresh gas and throw in a bottle of seafoam... its a small enough amount that it wont even be noticed.
