I have two Norther Lights Lugger generators. Both have separate fuel
pick ups from port & stb fuel tanks
. Both have separate valves on the fuel manifold. Both have serarate racor
fuel filters and priming pumps.
The problem is that suddenly both gennies have started losing power under load. When I lift
the top of the racors both have a considerable amout of air in them. I fill the racors to the top, screw down the lid and fire up the gennie and we're back in business - for a while. Then the same problem starts up again.
When the problem first started I replaced the o-rings and filters in both racors, but it made no difference. The only common factor is the fuel. I recently filled the tanks
where the fuel seems to be of lower grade (we certainly get a lot more carbon deposits around the exhausts on the side of the hull). However I recall
that the problem started before this latest fill-up.
I have checked the fuel lines (copper) from the tanks to the manifolds and can't see any leaks
, although I agree that suction leaks
would be hard to spot. I just can't figure out what's going on. The two systems are stand alone, so how can I have the same problem on both?
One further piece of information. I have the injectors serviced on both motors prior to leaving Mexico
. Could this be a factor? Also, is the air the cause of hte engines struggling under load. This morning the gennie cut out, but there was only half and inch of air in the racor
Thanks - I appreciate any assistance.
