Dear fellow sailors On my UFO34 I have a Thornycroft 90 (that's some 38 HP 4 cylinders) built 1976 or so. It was a pain bleeding the fuel system after changing the filters at the start of the season. Now it works, but each time I try to re-start after even one day, it refuses until I bleed the connection to the injectors. Once started, it runs perfectly. Two years ago I had a similar problem which was then solved by replacing a leaking fuel lift pump. I have been looking for leaks but haven't found one. Any suggestions? Greetings Erik
