Let’s talk fuel pumps.
I was at a buddy’s house the other day and he had just gotten his new dual action fuel pump delivered. We took it out of the box to look at it and as I remember it, you could bush the arm of the pump in by hand and hear the diaphragm pumping air. This pump arm only moved about an 1/8”. Even when I leaned it against the edge of the work bench and pressed with my body behind it, it still only moves a small amount.
When I got home I took the dual action that I got form Chevy Duty last year off the shelf and it is the same way, the arm only moves a small amount.
I don’t have any single action pumps around to compare them to but they have to have more movement to do any sort of pumping I’m sure.
Anybody run into this before?
