PAI Fuel Return Hose
The PAI Fuel Return Hose uses a U-shaped layout to go through tight routing paths found in Mack E6 and E7 engines. Its curvature maintains smooth circulation from the injector rail back to the return system, and the preinstalled fittings eliminate extra preparation during installation. The internal passage supports uninterrupted recirculation, helping the system stay balanced during long operating periods. Exterior reinforcement protects it from contact points near manifolds, brackets, or shielding, and the compact bend allows it to nest within crowded engine compartments without stressing the line. This arrangement fits engines where access around the return circuit is limited by surrounding components. Shop the PAI 2327 today.
