Replace your Cummins RV Diesel 450 Fuel Filter (5526400) or lose power climbing!-

Didn't think your 8.9 Liter Cummins diesel would rely so heavily on fuel filtration? According to Spartan, this filter could be the cause for loss of power in a big way. Spartan also advises changing both the fuel filter and the fuel/water seperator filter EVERY YEAR. Been doin' that? ... us neither and our engine went to 22% torque climbing in the Sante Cristo mountains near Angel Fire, NM. Change yours Now!
