Frequently Asked Questions
Q: Does this silver kit include the same seals as the black version?
A: Yes — both color variants include identical 4× Viton O-rings, 2× nitrile plunger U-cups, and one billet 6061-T6 aluminum bleeder screw. The only difference is the anodized color (silver vs black).
Q: Will this kit fix hard starting on my 2006 Duramax LBZ?
A: Yes. Hard starting after sitting overnight is a classic symptom of air intrusion through worn primer pump seals. This rebuild kit restores the fuel system's air-tight integrity.
Q: How do I know if my primer pump seals are bad?
A: Look for fuel seepage around the top of the filter housing, extended cranking before starting (especially after sitting overnight), and visible air bubbles in the clear fuel return line.
Q: Can I install this without removing the fuel filter housing?
A: Yes — the primer pump can be rebuilt with the housing still mounted on the engine. Removing the housing makes access easier but is not required.
Q: Is the silver finish as durable as the black anodized?
A: Absolutely. Both finishes use Type II anodizing for corrosion protection. The silver finish may show less wear on the wrench hex over time.
