So I finally got the engine running good, timing was dead on, fuel pressure was pretty steady, steady idle, things were good. I go out to the river, get one good holeshot and then by the time it got out of the water it was dying on me. My fuel pressure went down to about .5 psi. We let it sit like 10 minutes, and tried it again, and it started, and had a pretty steady 6.5 psi. Go to make a run on it again, and the same thing happened?
Its a mechanical pump, if it was a pushrod problem, the problem shouldn't be intermittent.
So, think its just crap in the tanks clogging the pick up tubes?
