Got it.Get a hose and a bucket. Put diesel in the bucket. Unhook the input side of the E2, (primary electric fuel pump. I would even take the E2 off, so I could look into the E2 opening, to loo for trash. Is there a tiny filter screwed into the E2? If so, I would replace it if there is. Its not an expensive part. But the will remove it from the equation. Then remount the E2. Hook the hose up to the inlet fitting. Then start the set. How long will it run?
sounds like we’re testing the primary.
I have another identical unit sitting next to it that runs flawlessly.
does it make sense to swap the primaries out or switch with the auxiliary ?
am looking for a replacement for the small filter.
took it off awhile back and it looked fine and had no resistance when I blew thru it.
