Description
Overview
The FASS PAK1001 Paccar Fuel Line Adapter Kit is a purpose-built solution for anyone installing a FASS Diesel Fuel System on a late model Paccar engine equipped with factory plastic quick connect fuel lines. Rather than trying to force incompatible fuel line fittings together or hack apart factory fuel hoses and fittings, this kit gives you a clean, engineered path to adapt your FASS suction and feed lines directly to the OEM Paccar fuel line quick connect system.
Sold as a complete kit, the PAK1001 includes two dedicated fittings designed to bridge the gap between aftermarket FASS fuel system components and the factory Paccar plastic quick connect fuel line architecture. In addition to adapting the suction and feed lines, this kit is engineered to bypass the factory Paccar water separator housing, streamlining your fuel delivery setup and eliminating a potential restriction point in the system.
Why It Matters
Modern Class 8 trucks running Paccar engines increasingly rely on plastic quick connect fuel line fittings from the factory, which don’t natively match up with the fuel line connectors used on FASS fuel systems. Without the correct fuel hose quick connect adapters, technicians and owner-operators are often left improvising with mismatched fuel hoses and fittings, risking leaks, poor flow, or a fuel system that simply won’t seal correctly. The PAK1001 removes that guesswork by giving you factory-matched fuel line fittings engineered specifically for this application.
Whether you’re a fleet technician standardizing installs across multiple trucks or an individual owner-operator upgrading fuel delivery on a single Paccar engine, having the right quick connect fuel line fittings on hand means the difference between a clean, one-time installation and repeated trips back to the shop. This is not a universal automotive fuel line adapter — it’s a Paccar-specific kit, so if you’re searching for something like a 2002 GS300 fuel line quick connect for a passenger car application, this is not the correct part; the PAK1001 is engineered exclusively for late model Paccar Class 8 diesel engines.
Fitment
Designed for Class 8 trucks powered by late model Paccar engines using factory plastic quick connect fuel lines. Confirm your engine generation and factory fuel line configuration before ordering to ensure proper compatibility with your FASS system installation.
