I have a Yanmar
3QM30F. I ran the engine
today as I normally do about once a month. After about 20 minutes the engine
stalls out as if it is out of fuel
. I check the Racor
, and the filter looks dirty so I replace it, fill it back up using the manual lift
pump and bleed the system.
I try again, and the same problem occurs. The Racor
is about half full only, but I can pump fuel
into it using the manual fuel lever. I tried the second Racor with the same results so I replaced the lift
pump. Since it is such a pain to bleed using the lift pump, I only run it for about 10 minutes, and then shut it off. The Racor is not filling back up.
I can siphon from the fuel line and lift fuel manually using the lift pump, but it doesn't seem to be pumping when running.
Any suggestions are greatly appreciated.
