HPFP TOOL
Disassembly & assembly of the factory HPFP housing requires a specialty tool to thread the assembly housing into the pump body. We have designed and manufactured ours to fit directly to 1/2″ drive socket and torque wrenches. This offers better leverage for unthreading the body and reliable torque spec to complete the install process without any hassles to make the job easy.
