Specifications
Manufactured at .031″ thickness with a print-o-seal configuration, this gasket supports proper sealing between the fuel pump and the engine mounting surface. Proper installation prevents fuel leakage, ensures correct pump alignment, and helps maintain system pressure and injector performance under heavy-duty use.
Given the Series 60 engine’s widespread use from approximately 1987–2011 in Class 6–8 trucks and coach/chassis applications, the gasket is used in many makes/models offering that engine. Before ordering, verify that your engine is indeed a Detroit Series 60 and that the original gasket number is 23505248 (or the cross-reference listed).
PAI backs the part with the quality and manufacturing standards expected from its brand — suited for service, rebuilds, and heavy fleet duty.
