I have a genset with a Perkins
107-3 (Perama M20) as the prime mover. Startup begins with turning the key for the glow plugs/electric fuel pump
to run for 10 seconds or so, then cranking and it starts right up.
Lately, after starting first thing in the morning, it has dropped off frequency and almost stalled when adding a load like the reefer. (There is no electric
feedback control loop for the speed)
Once it gets going, it is fine, and stays fine for any subsequent runs during the day/evening.
Through experimentation, I have found that squeezing the fuel
bulb I have inline for filling the racor
helps get the RPM
back up, so I think it may be starving for fuel
. I'm going to change the fuel filter
again (changed about 200 hours ago) and see if that could be starting to clog. Could this be my electric fuel pump
starting to die? It's one of the small NAPA ones.
Any insight appreciated!
