I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Duramax owners rely on this 6.6L fuel filter to extend component life and preserve fuel economy during daily driving and heavy towing.
