And lube the new o rings/seals with either diesel or Vaseline so they seal well.

Two questions
The fuel lift pump change out will certainly fill in a few blanks.
- What is the level of the fuel in the tank in relation to the Racor?
- Are both engines drawing from the same or different tanks?
And lube the new o rings/seals with either diesel or Vaseline so they seal well.
Ah Ha! So problem appears after filter change eh?
There is an O-ring seal around the shaft of the T-handle. Did you change that too?
Greetings,
Mr. BS. Aha! It has to be....EXACTLY the same scenario as I conveyed in post #19. Engine stalls, Racor low on fuel. Replace that 4' of heavy gauge flexible fuel line.
quick cheater for the lift pump instead of laying on the engine (god forbid it's hot):
1. drill a small hole near the end of that lever.
2. run a string/wire/whatever through it
3. attach it to the ceiling(bulkhead?) above the engine so you can just reach across and pull the string (line?) instead of leaning way down to get to the damn lift pump lever.
That is a great idea. I like the way you think.

Mr. BS. Another variable in the equation... http://www.parker.com/literature/Racor/Mobile_Air_Separation_In_Diesel_Fuel.pdf
Greetings,
Mr. BS. Just another factoid provided by my offsite expert but something else you should be aware of and he and I agree you DO have other issues. MY money, as I've said too many times, is on that supply hose from the tank to the Racor. I've got a bunch of crow recipes standing by.
... Always keep a spare lift pump on the boat!! They poop often and randomly.
One of the things that no one seems to have brought up on this thread is that Perkins engines have small rubber grommets in the fuel line connections.
For example, where the fuel lines enter/leave the fuel filter/injector pump/lift pump.
If you were to unscrew a pipe and withdraw it gently and look inside, you will see a black rubber grommet (like a small piece of black rubber pipe), you can withdraw this with a pair of small tweezers/fine long nosed pliers.
If this has been removed previously/ or is cracked/damaged in any way it's possible for a very fine amount of air to into the fuel system enter slowly and cause some surging, or if sufficient air enters, or throttle opened can stop the engine.
I hope you find this helpful.
Take the lift pump apart and see what's up.
