RE: Found a fuel leak...

Gonzo,
The pump is driven by a gear inside the front cover. The gear is held on by 3- 5/16 NF threaded bolts and t

has a short roll pin that aligns the pump shaft and gear. As scary as it sounds, I suggest you pull the round access cover on the front cover to get to these 3 gear retaining bolts. Pull the bolts out and the gear will drop down slightly , but it does not have enough room to fall out of the mating gear.
What this means is that you don't need to take the time to line upcrank gears, find TDC or even pull the timing cover off the pump to see the timing marks. It will only go back one way. As mentioned,before starting, locate the 2 timing marks on the pump housing and the front cover where it attaches. These marks should be aligned. As long as you spin the pump shaft when going back together to match your gear placement, then be sure that you put the pump housing timing marks in the same location- your engine will run exactly as it does now. Good Luck!
Steve
