Grizzly High-pressure Fuel Pump Installation Kit 01-04 GM 6.6L Duramax LB7
Description
Simplify high-pressure fuel pump service on your LB7 Duramax with the Grizzly High-Pressure Fuel Pump Installation Kit. Replacing the injection pump involves more than installing the new component itself; the necessary seals and installation hardware are important for completing the repair properly and preventing fuel leaks. Whether you're replacing a failed pump or performing fuel system repairs during a larger engine service, this kit helps bring the essential installation components together in one convenient package.
Intended for high-pressure fuel pump installation, this kit helps simplify parts sourcing when servicing the factory fuel injection system. Having the appropriate installation components available during the repair can reduce unnecessary delays and help ensure the replacement pump can be installed with the required sealing parts.

About WrenchConnected
WrenchConnected is an independent installation marketplace operating in partnership with Diesel Power Products.
How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.
