I have a question for you. I replaced my fuel lines but I cannot get any gas to the fuel pump. Do I need to prime it some how? If so, how do I do that? I was thinking I could pressurize my gas tank with my compressor to get the gas into the fuel line. Is that a good idea?
The fuel pump should pick up, you might have a plugged fuel line and what you should do is disconnect the fuel line from the pump and blow back in to the tank with the cap off. Also if you haven't already, change your fuel filter and make sure your fuel cap is vented properly so you don't create a vacuum in the tank. I hope this helps .....Big Tim
What Jim Said ! Remove the filler cap and blow back into the line leading from the fuel pump's inlet side , there should (must) be minimal resistance and in 30 seconds or so you'll hear the air bubbling into the fuel tank . If not , or you have to blow really hard , the intake screen is plugged or there's sediment in the line so disconnect it at the top of the tank and remove the pickup and clean it , DO NOT leave the pickup tube open in the tank ! Brand 'F' has very nice slip fit intake screens I use on most everything because they're cheap and adaptable to anything ~ you just shove it on , no clamps , tools or whatnot . Of course , using old window screen to make your own intake screen is acceptable as this is the farm way , this truck was designed to handle repairs like this . If you easily blew it back to the tank , re-connect the line to the pump and dismount the pump and work the lever by hand , in 5 ~ 10 strokes you'll have fuel gushing out , re-mount the pump and connect the carby line . You're too lazy to dismount the pump and want to do it the old Dealer Flat Rate way ? O.K. : prop the throttle to the floor and open the choke wide , operate the starter & place the palm or your hand flat on the carby's throat ~ the vacuum you feel will quickly suck fuel all the way from the tank , through the fuel pump and into the carby , when your hand gets wet with fuel , remove it and the engine will roar into life . Don't screw around cranking it for 60 secondsa then stopping to have a look etc. ~ you must crank it until your palm is wetted by the incoming fuel . I hope this works , I also hope you know not to smoke nor allow others to anywhere near this job as fires are a b*tch .
