FAQ

Will this kit fix 1/4-tank fuel starvation on my 2017–2023 6.7L?

Yes. This application uses a bed-mount bracket and a modified fuel module with a venturi return “Y” that keeps the in-tank basket supplied, preventing 1/4-tank issues when installed per the manual.

How much power will the DF-165-5G support?

The 165 GPH pump supports tuned/towed builds well beyond stock. For extreme race applications or very large injectors, consult us for the correct flow rating before purchase.

Does it replace the factory frame-rail feed setup?

It integrates with the factory frame-rail feed line. Suction is from the modified fuel module; pressure feeds the factory line, and the return provides venturi assist back to the tank module.

Is tuning required after installing this lift pump?

No tuning is required for installation of the lift pump itself. Always verify fuel pressure and leaks after install and follow the manual’s priming and start-up procedures.
