Product Description

The AirDog R4SBC134 Raptor 4G Lift Pump provides reliable fuel delivery for 2011-2014 GM 6.6L Duramax LML diesel trucks. Factory Duramax pickups rely solely on the CP4 injection pump to pull fuel from the tank, creating excessive wear and triggering low fuel rail pressure codes when running aftermarket tuners. The Raptor 4G supplies constant positive fuel pressure to the injection pump, eliminating P0087 and P1093 codes while supporting stock and lightly modified engines.

Featuring AirDog's 4G technology with a 4-bearing motor design and self-aligning gerotor, this pump delivers quiet, dependable operation with lower amp draw. The built-in adjustable diaphragm regulator is preset at 8-10 PSI and requires no return line, simplifying installation. The complete kit mounts to the frame jig in front of the fuel tank and connects directly to OEM fuel fittings for a clean, no-drill installation. Backed by a lifetime warranty from PureFlow AirDog.
