Fitment Notes: 2001-2004 GM Duramax LB7

Racor's PFF4245R2-04 ParFit Fuel Filter Head Assembly is a direct replacement for 2001-2004 GM Duramax LB7 diesels. Over time, the seals in the factory filter head are known to leak causing issues such as hard starting, air leaks, and priming issues. Replacing the entire assembly eliminates the hassle of having to rebuild the unit.

Racor is the OEM supplier to GM for this filter and assembly.

  • I brought the Racor Fuel filter head Assembly. For a 2003 Chevrolet Silverado 2500 Diesel 6.6 liter. It is working great at a greater price than the Chevrolet Motors Corporation. I would like to know the # of the fuel filter that is include with it and the price so i can order a few of then.
