From what I remembered, when I had it apart replacing the diaphragm, and
scratching my head on "how it works", The diaphragm itself acts as the
check valves. Photos show the diaphragm, and the two body pieces as
shown on "Ollie Oliver’s" site.
The one inner body half that you see has the recessed port on the bottom,
and on the other half, there’s a recessed port on the top.
The four center most holes in the diaphragm are just bolt holes,
and the other four holes are for the fuel path. These four fuel path
holes, two and top, two at bottom, straddle the center hole in the
pump body. It kind of made sense when I had it apart, but I can’t
make it work in my head right now, lol.
Had to go to the big city today shopping, but may go out to the
garage now and take it apart, see what could be wrong, and
refresh myself on "how" it should work. If I stay inside I will
need NoDoze to stay awake to watch the VP Debate 🙁
Would like to test this impulse pump on the bench, but not sure
what I’d hook the impulse up to. Any ideas?
