Got my new motor in and its getting spark but no fuel. I put a walbro 225 pump in during the install of the new motor but I hear the pump running but its not putting any fuel to the rail, I have a decent amount of gas in the tank I dont get it, the pump is running but no fuel... I cranked it over for about 6 minutes on and off does it maybe need some kind of prime or somethin since all the lines came off and the pump was out?? =(
