Great, we have managed to trace the source of the problem.

Beyond this, I wil to know if you would like us to send you another pump loom? Sometimes the pin inside plug may be mis-aligned and upon insertion, the mating part may become distorted. Let me know which part of the connection caused the intermittant connection so that I can send you replacement. Fix it good now rather later.

The priming pump activation is done on a separate circuit. It is triggered by the manifold pressure switch (806-157), I think you have found that out.

The 806-157 is factory set at 10psi. 1/4T clockwise from that point will increase the trigger point by ~2.5psi or so. The setting is user determined, so 1.4T clockwise will only delay the trigger point - doesn't degrade the performance of the system.
