I'm thinking of a way to modify a mechanical fuel pump so as to attach a priming lever. I've seen a few diesel motors that have this feature to pressurize the system and bleed the air from the system after changing the filters etc. This would be a good thing to have on a older car that isn't run every day so you don't have to crank the engine for so long before starting. Just pump the lever a few strokes then hit the switch. Has anyone ever done this or know how to modify a pump in such a manner? Or know of any pumps that would fit Chevys / Fords that already have this feature? Thanks.
