  1. OWNER - I own a Hatteras Yacht
Hatteras Model
43' DOUBLE CABIN (1970 - 1984)
Started experiencing a fuel problem upon hot restarts.
Engines start cold and run fine for hours. After shutting down for 1 to 3 hrs. one or both engines will start and run for a minute then stall. Going into the engine room and releasing the T handle on the Racor produces a air suck sound. A single pump on the manual re prime pump and engines are good to go again.
This just started recently after the summer heat set in here.
Any thoughts as to what is happening. ????
The engines are Volvo diesels.
Thanks, Capt. Rob
 
Any suggestions for trouble shooting this ?
 
Fuel cooler? I haven't heard of this happening on performance gas engines, but never on diesel but I would check into it.
