Measure the pintles and the bore and be sure they are fitting properly... Like mine where gummed up with coked fuel and the pintle needles where about 1/2 thousandth tight. After cleaning then they fit good and smooth again.Might also look into your fuel filter and the media your using I aim for a 2-3 micron filter. Using either a Fleetguard or a Donaldson filter.
