High Pressure Fuel Pump - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Has anyone successfully run a LFX HPFP on the LLT? I remember a vague reference that someone did it but it required bending one of the hard fuel lines. I’m not trying to go crazy and run a LF3/4 pump with a Ferrari lash or anything, just wondering if the better flowing LFX pump could be a legit option for more fuel under boost.

Thanks

You could reach out to Overkill Will who might have some experience with this.

No doubt. Will did reply with this helpful info:

At the moment there's no HPFP for the LLTs. The LFX/LF3/LF4 pumps are incompatible electronically, they're Hitachi while the LLT is a Bosch unit.
