Ok . I have a facet pump hooked up on injected motor using for primer system. Car cranks fine after little tuning. Use for cranking only right now.
Issue I think I am having is when shutting motor off. I pull fuel shut off,motor revs up as should before shutting o0ff,except it keeps running and running(no batteries here). I am thinking the vacuum maybe pulling fuel thru the electric pump. Pump is about 12" from main line from tank and mounted low so as to keep it wet for easy priming.Line from pump goes to a jetted line that's in middle of injector with 4 spray holes drilled in it that spray up ward and mix with incoming air.
Anyone have issue with fuel being pulled thru pump?
