2wd 5030SU, 1900 hours. After running approx 45 minutes, the engine sounds starved for a few moments, sounds like it's missing then won't rev. Resumes normal power shortly thereafter. It's more significant than one fuel injector intermittently failing. No idiot lights on, temp gauge is at the 3/4 mark. Drained all fuel, replaced filter 2 hours run time ago, filter nowhere near as heavy as in the past, added Lucas treatment and still have the issue. Please help, I am a one tractor farm and REALLY don't need the expense of an injection pump!

Check water seperator fuel cut-off valve for a
plugged screen. I had a M4900 act similar to your
tractor and I found tiny white screen in valve that
was plugged. I cleaned screen and problem was

from what you have written, it sounds like the
filter isn"t getting enough fuel, never seen the
tractor you have, but something is slowing fuel
flow tot the filter, there may be a pencil style
filter in the tank, you could try removing the
fuel line from the tank to the filter and checking
that there is good flow from the tank, blowing
back though the pipe work once disconnected might
help if there is something in the fuel line. the
other thing that springs to mind is the lift pump
(if it has one). I"d doubt it"s the injection pump
from what you describe...
