Detailed Description

Mahle B26454 is a fuel injection pump mounting gasket used on diesel-powered Chevrolet, GMC, and Hummer platforms where the injection pump seals to the engine mounting surface. The paper gasket material supports a precise seal during pump service, helping restore the joint between the pump and housing. This part is a practical choice for diesel repair jobs on Chevrolet C2500, GMC K3500, and Chevrolet Tahoe applications, as well as many other GM truck and van platforms.

This part cross-references FEL-PRO 70150 and General Motors 10137486, 14022651 for the same application. Mahle B26454 is also a direct service option for technicians working on Chevrolet and GMC diesel injection pump reseal jobs.

Common Repair Uses

• Fuel seepage at the injection pump mounting surface
• Loss of sealing after pump removal or service
• Maintenance on diesel injection pump assemblies
• Replacement of a damaged or compressed paper gasket
• Restoring a proper seal on GM diesel truck and van platforms

Installation Notes

Clean both mating surfaces thoroughly before installation and remove old gasket material, oil residue, and debris. Verify the pump and housing surfaces are flat and undamaged, then align the gasket carefully during reassembly to maintain an even seal.

Quality Assurance

Mahle sealing products are used by OEMs and technicians worldwide, and this gasket reflects that focus on consistent sealing performance for service and repair work.
