Hi folks,
I have a 1988 Catalina 20 mk2 with a universal Diesel M25. I have replaced with NEW the dip tube in the tank, the hose to the Racor the Racor and hose to the Electric lift pump and the pump and the hose to the engine. all are new. I also replaced the seal and filter on the 2ndary fuel filter. AS I understand it this is all of the supply side of the fuel parts. So there should be no air getting in here and yet I still have air in the fuel. After it goes to the engine it is under pressure so air should not be able to get in. To get the engine to start I have to prime the injector pump with fuel by the electric lift pump. Then I have to crack an injector nut at the injector pump and start the engine. then she starts right up. Sail for several hours and she starts right up. Leave it over night and I have to bleed it again. Any ideas ???? Help I have $2k into this and I am no better off then before.
