There was a thread on this forum within the last year where the OP was tracking down a mystery air leak that turned out to be the fuel heat exchanger was cracked just enough to leak air but not fuel.

I bypassed the fuel heat exchanger 2 weeks ago, same results.

I can see some bubbles going into the pre-filter, but very hard to see and not a lot of air bubbles. The 2 lines going in & out of the fuel pump (i think that's what it is). It's mounted on the lower left side of the injection pump. There is quite a bit of air in that area.
When I replaced the clear lines yesterday I also placed a small piece of blue paper towel in each bore and cleaned the inside of the bores with emery cloth to remove any corrosion, sharp edges, dirt, etc, got them nice and shiny, then of course removed the piece of paper towel and wiped out the bore with some clean diesel fuel on a blue paper towel.
