My pump has the pn on it. It’s also the same pn from a 19 zl1 can’t even look up the pump for a 2020 which should still be the same pn of 12694529

If what was previously said is true its possible to check the wire schematics for that pump connector vs the other and if indeed it is a lt4 just fabricate a wiring harness for it with appropriate connectors.

This OEM GM factory pump is a great upgrade to your LT Gen V build. The stock LT4 engine mounted high-pressure fuel pump will allow 35% more fuel flow with supporting modifications. SDPC specializes in late model LS and LT engine builds and we have seen serious HP numbers utilizing these factory direct-injection fuel components.

Looking to see if there’s a replacement harness or why someone did not wanting to cut up my harness for a connector if I can just get a new harness that works with what I have. Would be easier and quicker just don’t know if ones made.
