For some reason it only let Air in when it was hot under the hood. Some SAE 5/16 30R7 Fuel hose that ever Auto Parts store sells (also rated for Diesel) took care of the problem for a few dollars.
But, also look under your Fuel Tank and see if the Hoses there are seeping Fuel. If so they need to be replaced also.

This is solid gold, I've had this precise problem with my car ever since I obtained it a year ago. It also sounds like I took the same backwards journey many of you did, starting with purchasing a gold rack dampener bolt only to find that it didn't help.
Diesel911 and snookwhaler, I was hoping make sure I understand exactly which lines you replaced. Both of you are talking about the two opaque black fuel line segments connecting to barbs and held on with hose clamps (compatible with 5/16" hose) that go between the hard line and pre-filter, then from the pre-filter to the lift pump, correct?
I'm wondering whether you two just replaced these opaque ~5/16" lines, or did you ALSO replace the fuel tank to hard line hose, and the three transparent (at least they were originally) lines that connect to banjo bolts:
1) lift pump to fuel filter
2) fuel filter to injection pump
3) (can't remember precisely) injector return line to fitting on filter housing, leads to cigar hose?
I really hope this does the trick, and am quite excited at the prospect of a calm engine. Thanks a lot!
