Racor PFF19579 Fuel Filter for 00–10 Dodge 5.9L & 6.7L Cummins

 The PFF19579 Racor fuel filter element is engineered to meet or exceed OE specifications for filtration efficiency and flow on late 2nd‑gen, 3rd‑gen, and early 4th‑gen Ram Cummins trucks. Designed as a direct replacement for the factory element, it helps protect high‑precision VP44 and common‑rail components from wear caused by dirt, rust, and water contamination. Cross‑reference coverage includes popular OE and aftermarket numbers such as 5015581AA and 05015581AB, making this an easy drop‑in solution when matching to factory part numbers or other brands. Ideal for daily drivers, tow rigs, and work trucks, the PFF19579 is a solid choice whenever a fuel filter service is due.​

Symptoms of a restricted or overdue fuel filter

If your existing filter is clogged or failing, you may notice:​

• Hard starting, extended cranking, or stumble right after start.

• Loss of power, especially under load or at higher RPM.

• Surging, hesitation, or rough running as fuel demand increases.

• Excessive injector rattle or rail pressure fluctuations on common‑rail trucks.

Replacing the filter with a fresh PFF19579 is a common first step before deeper fuel system diagnosis.​
