This lift pump is designed for seamless integration with factory fuel lines, and its straightforward installation makes it a highly efficient upgrade for Duramax owners. Additionally, the pump outlet and return are threaded to accept -8 O-ring fittings, making it compatible with custom fuel lines or aftermarket filters for further customization.
