Ball-squeezing can't be the only answer.
I've got a Universal M4-30 diesel with an intermittent issue where after a few hours of running under load, it shuts down due to lack of fuel. All the obvious ideas (obvious to me anyway) I've tried: cleaning fuel tank, replacing all the diesel, clearing fuel vent in the tank, clearing all the fuel lines, changing all filters, changing all fuel supply hoses, cleaning the lift pump, changing the 'lift pump' - heck I've even installed a squeeze-ball style inline pump-ball (like for an outboard) in line ahead of the lift pump. And that actually alleviates the issue temporarily. But unless i send crew below to squeeze that ball, she'll stall in anywhere from a few minutes to as much as 30 minutes. I'm baffled - no pun intended.
Out of desperation, I've got a new lift pump coming in the mail that I intend to place in-line where the pump-ball is. I'm thinking this won't fix the real problem, but it may save my crew (and wife) from strangling me every time I scream: "SQUEEZE the BALL!!!.
Can you help me figure this out - or at least figure out what to try next?
