Remanufactured high-pressure oil pump for late-build 6.0L Powerstrokes. Low ICP, hard hot starts, or a truck that dies under load usually lands here — the HPOP is what drives the injectors on a HEUI engine. Every exchange pump is bench-tested before it ships, with gaskets and hardware included.

Why Buy From Valley Fuel Injection
We are a diesel fuel-injection and turbocharger shop in Woodland, CA — rebuilding pumps, injectors and turbos on our own benches since 1993 — not a drop-ship storefront. When you call, you talk to the people who test these units. We verify fitment against your engine serial number before anything ships, so the right part arrives the first time.
Diagnosing an ICP complaint first? We test HEUI oil systems in-house — injection services.
Ready to order online and ships free ground in the lower 48 states. A refundable $285 core deposit is added at checkout and refunded in full when we receive your rebuildable core. Questions on fitment? Call 530-668-0818.
Pricing covers the unit itself. Any applicable sales tax and the refundable core charge are additional; ground shipping in the lower 48 is free. Buying tax-exempt? Qualifying diesel repair shops, fleets, farms, and agricultural operations can purchase tax-free. Set up tax-exempt purchasing once and every qualifying order is tax-free going forward.
