1991 ford f150 custom truck, straight 6 cylc, not a v-6: this truck has two gas tanks. i changed the fuel filter. it was about in the middle of the truck against a beam. does this truck have two fuel filters? i cannot find the second filter for some reason if it does have two filters.

SOURCE: remove fuel lines from the fuel filter on a 93 f150 ford truck

There is a special tool used to disconnect the lines from the fuel filter. You should be able to get them at any local automotive shop, i.e., Pepboys, Autozone, Chief Auto. It should be relatively cheap to buy this tool.

SOURCE: 1991 ford f150 no noise from fuel pump and truck will not start

get a code reader like the Actron CP9015 Code Scanner, 20 dollars and will flash codes. if it will not diagnose itself, the ecm must be replaced. this fixed my dads truck with the same problem

SOURCE: where is the fuel tank selector valve exactly located

Just in front of the side tank is the selector.Very common problem.The rear fuel tanks pump quits.

SOURCE: fuel swith depressed not poping back up

Try jumping the switch 96 is directly related to the fuel pump power.

Use a jumper lead in the connector to see if it will run that way...if so ..BAD SWITCH
