A day at the school
Here is it what learned:
1, there are fuel grommets in the end of the supply and return lines that create a compression
fitting. These are on the 1/2" fuel line connections. If you don't connect into those before tightening they will leak like crazy.
2. You can pull the Govenor without removing the heat exchanger . Must remove some injector lines and fuel lines 1st. The splined bolt heads are 1/4" and we had to grind the wrench head so that it would fit the tight opening. Figuring this out took too long. Once we had it we made progress.
3, I stopped my leak at the Govenor and still had a drip at the end of the pump. It was leaking a drop ever 10 seconds. I put a wrench on the 1/4" bolts at the end of the pump and got an 1/8th turn. Now it leaks
one drop per second. (Bummer... After a day of work it is worse than when I started)
I am tempted to see if there is a seal behind this 4 - 1/4" bolts but it looks a little hairy in the schematic
I called Stewart marine
at 4:45 and missed them . My thought is that I too must have the internal leak and need a new pump.
Does it make sense to buy one to keep around as an extra?
What should I expect to pay?
Given that I am stopped at sitka not sure what the best approach would be.
