The spin on fuel filter,currently a Baldwin BF1253, is continually popping the rubber seal on the filter,at 1 o`clock. The Manual says only ever hand tighten it.
When we surveyed the boat it was leaking, the mechanical surveyor refitted it,and later put on a BF1253 which was ok,but since replacing it, it seals at first,then leaks. We tried hand tightening,hand tightening plus some tool force,lots of tool force,still leaks. Usually it`s fine after fitting,then next time using it,it stops running due to fuel leaking and not getting to the injectors, or I discover it is leaking but still running on inspection,or by fuel in the bilge overflowing the tray under it.
The Sydney Onan agent was unresponsive.I had a mechanic fit the filter last time, it leaked as usual,he wants to try a Fleetguard filter. He says the seat in the filter head was ok,though it doesn`t feel all that deep to me. We both wondered about a pressure build up at the second use,but how and why?He`s not seen this problem.
While typing this, the mechanic called to say he is trying a different (?non Onan) filter head, and it is not leaking (not yet, I add, resignedly), and now says, with the old filter head off, that it looks like the filter was going on at a slight angle. So I guess wait and see,but,if anyone has a clue, please respond anyway.
