4400 fuel problem

[snoman]

I have a 2012 4400 L . The fuel filter runs out under load. If you wait about 3 minutes it refills and the engine runs again. the machine has 50 hrs on it. what advise can you suggest . The machine is 1 mile in the woods

Check to be sure tank is venting. Try running engine with fuel cap loose or off. Check for a good fuel flow from tank.

If the tank vent is good, then you have bad fuel or something growing in it. Change the filter, the fuel and treat it, might need to clean out the tank...

Also try to crack the injectors and bleed the air out, sounds like there could be air in the system. Did you replace a fuel filter recently?

If engine will run for 3 minutes I doubt seriously if air is in inj pump or inj lines. I still think it's a lack of good fuel flow from the tank.

Wow 50 hours, you are basically talking a new machine here. I would disconnect the fuel line going into the fuel filter and see how quickly you can drain the entire tank into a container.

What kind of ambient air temperatures has the machine been exposed to?
