My MF 390 just stopped. Quite abruptly. Bled the system and off we go again. Then, stop! Again. I cleaned the lift pump which was full of gunk, then onwards with more problems which I will not bore you with. Couldn't resurrect the lift pump, so replaced it along with a new fuel filter. I have syphoned off a lot of fuel with gunk in it and fuel is finally reaching the (replacement) lift pump although intermittently which I assume is again choking. Checking that again is today's project. Is the only solution to take the tank off? And when I've done that, how do I make sure the bug doesn't come back again? There really was a lot of debris in it for which I blame the previous owner. The tractor with a four rotor tedder on the back is currently sitting in the hay field and not ideally located for repairs. Thank goodness for the quad as it saves walking whenever I need a different spanner.
