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.

Frequently Asked Questions
Q: Will this fit a 2005 Duramax LLY? A: No, this housing head is specifically for 2001-2004 LB7 engines; LLY models use a different fuel filter head design.
Q: Do I need a new filter element when replacing the housing head? A: The new filters are not included, but it is recommended to install a fresh fuel filter to avoid contaminating the new housing head.
Product appearance and specifications may vary slightly by batch. Compatibility may vary by serial number. Verify fitment before purchase.
