Frequently Asked Questions
Q: Will this kit stop my Duramax from losing prime overnight?
A: Yes — air intrusion through worn primer pump seals is the #1 cause of lost prime in Duramax engines. This rebuild kit replaces all critical seals to restore an air-tight fuel system. If your truck starts hard after sitting overnight, this is likely the fix you need.
Q: Is the billet bleeder screw compatible with all Duramax fuel filter heads?
A: Yes, this billet aluminum bleeder screw replaces the OEM plastic screw (GM part #97363195) on all 2001-2013 Duramax fuel filter housings, including LB7, LLY, LBZ, and LMM engines.
Q: How long does installation take?
A: Most DIY mechanics complete the rebuild in 30-45 minutes. The kit includes photo instructions for seal placement. Lubricating the seals with clean diesel fuel before installation makes the process smoother.
Q: Are these seals compatible with biodiesel (B5-B20)?
A: Yes. The Viton O-rings provide excellent resistance to biodiesel blends up to B20. The nitrile U-cups are also biodiesel-compatible for normal blend ratios.
Q: What's different between this kit and buying just the seals?
A: This kit includes the billet aluminum bleeder screw upgrade — a permanent fix for the commonly stripped OEM plastic bleeder. Buying the screw separately costs more than the bundle price.
