I have to start a 12 valve tomorrow morning and have no fuel lines to the tank. I will be using a fuel can under the motor. I would think that I need a return line into the fuel can as well?

If the lift pump is not functional can I plumb a electric pump inline or do I need to reroute the lines from th lift pump?

thanks

More info , why do you say no fuel lines to tank , what do you mean by fuel can under motor , are you planing on not using the stock tank ?
An electric pump could work , but needs the same pressure & volume , 26 - 36 psi , about 55 gals per min .
the return line is on the main pump near the front , and on the motor side of the main pump , do not remove the line there , that bolt is the Over Flow Valve , it controls the pressure to main pump , follow line till it changes to hose , then thats where you want to have the return go into can .

 

More like 55 gals per hour

Return in red

 

The tank is full of water. Fuel can under the motor to keep me from dumping it over while working on it. If the lift pump is not working I need a pump to get the fuel into the injection pump. just thinking out loud. I want to be ready for any scenario

thankyou

 

Oh now its a marine engine .
I would disconnect the fuel line going to to the main pump , then use the primer pump to flush what ever may have gotten that far , into a glass jar so the you can see any contaminants .

 

no it's a truck engine that had been vandalized while in a repair shop. I got it to run using a electric pump. pain in the neck! that little preformed hose on the lift pump/prefilter was bad so I used a piece of garden hose. I guess it was sucking air thru the crack n the hose
thanks again
