H3LP!

Having issues with a 2006 F750 with a 230 HP Cummins. Having replaced the fuel/moisture separator more often than recommended, having fuel flow(?) problems with my rig. It will loose power, and stall while driving. Have to pull over and drain fuel/moisture separator, and open the tank cap to start the motor. Sometimes when I do this, I seem to have pressurized air coming out of the drain valve on the ms. This has happened since new. Lately, this does not solve the problem. A few days ago, after completing the above, still hesitates under acceleration. Is there another filter I am missing? Any help would be greatly appreciated, thanks!

 

Not sure, if theres a fuel heater there is a screen in there, just unscrew the bottom of the heater bowl and remove the screen and clean or replace. Maybe you need to clean out your fuel tank.

 

is it poss. tank vent/cap pluged?
