Pure Power HP4 to DCR Pump Conversion Kit 17-22 GM 6.6L Duramax L5P
Description
Are you ready to stop worrying about high-pressure pump failures? This HP4 to DCR conversion kit is one of the most effective upgrades you can make. The factory Denso HP4 high-pressure fuel pump is a solid design, but it can struggle under heavy use, contamination, or tuning. This conversion kit swaps the factory pump for a proven DCR (Diesel Common Rail) pump engineered for stronger pressure consistency, better flow, and longer life, all without ECU tuning or modifications.
Built as a drop-in solution for your L5P Duramax, the kit includes a replacement DCR pump and all the supply, return, and high-pressure fuel lines you need for a straightforward installation. Each component is designed to meet or exceed OEM quality, giving you improved durability whether you’re daily driving, hauling heavy loads, or adding performance upgrades down the road. With a DCR system in place, you’ll have confidence that your high-pressure fuel delivery won’t be the weak link in your Duramax’s performance.

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.
