Constant vacuum leaks from the Winn. Fixed mine 3 times. Replaced with a Parker racor. Not a field job. Replaced the fuel lines also as the low sulphur fuel destroys the rubber oem lines. HPDM? Replacement is required.
Ask about fuel lines. If not budget $2k plus the filter at $350 plus install.
If the tank get low on your drive home and the tank is lower than the motor when parked overnight and it won't start that's a vacuum leak and/or the Winn.
There is a button on the Winn to reprime it. May take several times,
Keep the tank full when parking overnight and/or a slight nose up parking place.
Low tank(1/2 or less) and nose down several times was when I noticed the problem.
Major Cummins shop in LA mechanic used to work for a major truck line when the Winn's were new and being used diagnosed the leak and bypassed the unit then continued the dyno run
