Or another idea, put some fuel in a jam jar, with the tube going to the pump (suction side) then another to a empty jar, turn engine over and see how much it is pumping. (remove the plugs to help the engine spin over easier) You will see if it's pumping well then, it's not known for new parts to be faulty! Hope those ideas help Nick_Jones wrote: Carefully check for air leaks on the suction side of the pump plumbing as it doesn't take a very big leak to stop it priming and there won't be any tell-tale wetness either. Nick I'm currently suffering fuel feed problems too. Thanks very much for some great ideas, guys. I'll be trying these on my car. 8)
