JDMSPEED Fuel Lift Pump for Chevy/GMC 6.5L (1992–2002) — Direct-Fit Replacement with Mounting Gaskets

JDMSPEED diesel fuel lift pump E8413 is a direct-fit replacement lift pump engineered to restore reliable fuel delivery on 6.5L Chevy and GMC trucks (1992–2002).

This JDMSPEED pump replaces OE and common aftermarket numbers (E8413, E520, 8012, 15754298, OT18046, BGV100, P74222) and is supplied with mounting gaskets so you get a near-ready swap for C2500/C3500 and K2500/K3500/G2500/G3500 models. Built with precise internal gearing and tight clearances, the unit is designed to stabilize flow and pressure for older diesel engines. Before ordering, confirm fitment for your specific year, chassis, and fuel system.

How does this pump match my 6.5L Chevy/GMC fuel system?

The JDMSPEED lift pump is manufactured to the inlet and performance dimensions used on many 6.5L installations, making it a suitable replacement for the listed part numbers. Its inlet threading and flow/pressure ranges align with factory requirements for lift pumps on these trucks.

• Direct-replacement for many OE numbers including E8413 and 15754298
• Inlet thread: M16x1.5-6H for correct seal and fit
• Designed for C2500/C3500, K2500/K3500, G2500/G3500 1992–2002 models

What performance can I expect — flow rates and pressure?

This lift pump delivers a controlled flow and pressure band tailored to diesel feed requirements. Expect free-flow rates between 25 and 35 gallons per hour and operating pressure roughly between 8 and 12 psi, suitable for maintaining supply to the injection system or primary pump.

• Minimum free flow: 25 gph for consistent feed
• Maximum free flow: 35 gph to handle demand spikes
• Operating pressure range: approximately 8–12 psi

Is installation difficult and what’s included?

Installation is straightforward and does not require specialty tools; the pump uses a modular styling to simplify mounting and plumbing. Your purchase includes the pump and the gaskets shown in the product images, so you won’t need to source additional basic sealing parts for the swap.

• Includes pump and mounting gaskets as shown
• Modular design for easy start-up and quicker replacement
• No special tools typically required for installation

How is build quality and longevity compared to originals?

JDMSPEED emphasizes precise gear profiles and very small internal clearances to improve pumping efficiency and reduce wear. The careful machining and assembly practices help the pump maintain stable delivery over time, reducing the risk of cavitation or uneven feed that can shorten component life.

• Precisely cut internal gears for smoother operation
• Tight tolerances to improve efficiency and reduce vibration
• Quality control focused on consistent fuel delivery

Who is this for: The JDMSPEED E8413 replacement lift pump is aimed at owners and technicians working on 6.5L diesel Chevy and GMC trucks from 1992–2002 who need a reliable, direct-fit lift pump. It’s suitable for fleet mechanics, DIY restorers, and anyone replacing a worn or leaking lift pump, especially when matching OE part numbers is necessary. Verify vehicle fitment and part interchange before purchase to ensure correct application.
