This kit includes a Weber 38 DGES carburetor, an adapter plate, a Carter low-pressure fuel pump, a Redline air filter, a universal cable linkage kit, and a Malpassi regulator. Installation involves disabling the factory in-tank fuel pump and mounting the new fuel pump near the rear of the truck, requiring modification for a new fuel pickup in the tank.
Show original supplier description
The Redline K644-38 conversion kit transforms your Nissan D21 truck's TBI system into a performance-oriented Weber 38 DGES carburetor setup. This comprehensive kit includes the Weber 38 DGES carburetor, the 99004.644 adapter plate, a Carter low-pressure fuel pump, a Redline air filter, a universal cable linkage kit, and a Malpassi fuel pressure regulator. This conversion requires specific installation steps. You will need to disable the factory in-tank fuel pump and relocate the new fuel pump, wiring it in near the rear of the truck. Additionally, modifications will be necessary to create a new fuel pickup in the bottom of the fuel tank. All components included in the kit are also available for individual purchase should you need to replace or upgrade specific parts. This kit is specifically noted as being popular in areas without road salt due to the Nissan D21 truck's susceptibility to winter road treatments.
