I'm hoping I can get some guidance on this.
Our
boat has a Paguro 9000
generator installed. In one of the lockers inside the
boat there are valves to select which
fuel tank the
generator pulls and returns from/to.
Also in that closet is a
fuel pump that pumps the
fuel from the aft
tanks (about 20 feet aft) up to the generator's
Racor 510
fuel filter.
When I first got the boat I could hear the
pump vibrating the entire time the generator was running. Over the last two weeks, we've heard the
pump less often but didn't notice anything different with the generator.
Today, the generator ran great under 50% load but at and above that, the RPM's dropped and the Hz dropped until I shed load, then it would run fine again.
I'm not even close to being a
mechanic but it seems to me that this is a
fuel issue. There are 60 hours on the generator and I just completed the 50 hour
oil and
oil filter change.
I have a new
fuel filter but I don't have a way to get clean
diesel into the new filter and I don't see a way to manually pump fuel up to the filter once I change it.
When I start the generator, I hold down the start button and the pump starts, the fans for the compartment turn in, and the glow plugs start. Then after 10 seconds or so, the starter engages.
Can I just do that a few times and let off of the button before the starter engages to fill the filter?
Does this sound like a filter or a pump issue?
