A tow bill is cheaper than a new engine if rpms exceed maximum and breaks the block due to overfueling caused by excess fuel or oil being burnt. Sep 15, 2014 · EPA 2010 and later DT, 9 & 10 engines use a fuel module that incorporates many features, including an electric fuel pump, fuel heater and fuel strainer. -The fuel strainer can be seen when the pump is removed from the filter module. The strainer should be cleaned at the filter replacement interval (30K miles / 43K Km / or 12 months). Most Maxxforce engines have some kind of reset procedure for DPF cleaning. This is mostly for record keeping, and/or making a latched active code go inactive. Replacing a DPF will not cause a shut down and no restart. Something else is going on. ...
