RE: Fuel leak from top of gear pump head
Quick update, fired up the truck, no visible initial leaks. Let it idle (700rpm) till temp began to read on dash, then set cruise to highest idle (1150ish) to bring the coolant temp up to normal op temp.

Coolant temp at the thermostat housing was about 175, temp at the fuel pump head reached 153, no leaks so far. Brought the rpm up to 15-1700 for 5min or so, then let come back to idle for an additional 15min. All in all, it ran for approx 45min with no leaks noticed. Still doesn't mean it's fixed, but is doing better than the original test on Fri whereas it would begin to 'wet' the threads within a few min at operating temp.

Waiting for the computer to charge for a leak down test. If it passes, I will make about a 7hr run today and report back.
