High lpfp psi after stg 2 pump install

bimmertt · 12-01-2018, 11:49 PM

i just installed my stage 2 pump and noriced that the psi at idle and normal driving hovers around 85psi. This seems a little high compared to my stock pump. Is this normal? if not, will it adapt over time or shluld I clear any adaptations? Thanks in advance.

I noticed the same thing after I installed the Fuel-IT Stage 2 Bucketless with Holley Fuel Hydramat.

My LPFP psi was around the 70s on the stock LPFP, but after I upgraded, it's in the 80s+ on idle now.

I'm sure this is normal as I've ran the setup for a few months now without any issues. These pumps are pumping fuel at a faster rate, so in turn the psi would be higher.
