I got a buddy in the army who is new to diesel. He just picked up a 89 d250 and wants the pump tweeked nothing outrageous. Who in way up NY can work on his pump. Thanks in advance
How much of a tweak does he want? There are quite a few good write ups on how to do it on your own. If he wants to get serious I suggest Giles To go threw his pump.
A good lift pump is needed before playing with any settings on a VE. Not a good stock VE lift pump, a good flowing pump at low pressures and cool fuel.
