No. This product is the 39.50" stainless steel braided hose only for 12V applications. For a complete coolant bypass solution, pair it with a compatible Fleece coolant bypass kit such as the FPE-CLNTBYPS-CUMMINS-12V-SS kit.

This hose is part of the Fleece coolant bypass system that routes coolant from the thermostat housing to the rear of the engine to stabilize temperatures across all cylinders and reduce pressure spikes that can blow out freeze plugs.

It is engineered for Fleece coolant bypass kits on 1994–1998 12V Cummins. While it may physically fit other setups, best results come when used with Fleece-branded components.

The stainless steel braid helps prevent hose expansion under pressure, improves resistance to abrasion and heat, and offers a longer service life compared to typical rubber hoses—especially important on high-horsepower or heavy-towing trucks.
