I replaced my HPFP on Wednesday. Car has been running very well since. Today I thought I’d take a peek to make sure all was well and I noticed a large wet spot under the pump. I know when I was putting the fuel lines back on I slightly overtorqued the one that goes to the injectors. I loosened it and tightened to spec but I’m wondering if I may have done some damage and created this leak. Does anyone have experience replacing the pump and if so how to troubleshoot what is leaking? Also want to make sure there’s no way it could be from the AC compressor or something... I’m not sure what the location of that is.

I honestly would replaced the over torqued junctions. For this job proper torque is super important. When i did the injectors i had to torque all 6 of the joints and never had issues after the job with fuel leaking. Over torquing most likely caused damage.

Okay I will do that. If my rail pressure is fine do you think there is any issue with driving the car in the meantime? It is a very mild leak.

We are talking fuel leak huge safety concern. But obs you are the best judge to that if its small and away from heat maybe ok but then again any spark or source of ignition around that area and BOOM. Its not diesel or kerosene/aircraft fuel.. gasoline is immediate propellant. Not something you mess around with honestly.
