Currently Running a MEP-803a During Beryl Hurricane - Question

[scjarena]

Located south of Houston area, may have a few more days till power is restored. I currently running a MEP-803, and starting to notice an occasional misfire, which is best I can describe. Does anyone know of anything to look for, or help with keeping this unit going? Its still generating power, I don't notice any change in exhaust color or amount while its "acting up" With about 260 hours on it when I bought it, purred like a kitten while running. Now its like an occasionally slight random, rapid fire miss while running. I tried to record the sound, but I can not hear the slight miss in the audio or video.

Does anyone know these units well here? Any things I can be checking? If I can find a fuel filter locally quick, I could replace it. Drain filter housing? I'm running pump gas at the moment. Should I try any diesel fuel additives? I'm just hoping it will hold up the next few days until I can really take a good look at it and get it "tuned up" or whatever I need to get it running like it should.

Thanks

maybe open the drain on the water seperator to make sure you do not have water built up, any diesel fuel treatment is not going to hurt anything, Check for dry cracking in a fuel line letting just little bit of air in the sytem,

+1 on water in the fuel, both from the perspective of an intermittent misfire, and being a generator running post hurricane in a humid area...

Try draining the water block filter as @FarmingSmallKubota suggested, and then add some extra cetane booster/water emulsifier.

All the best,
