Question for A&P's, engine gurus, gear-heads - What is normal fuel pressure limits for the engine-driven fuel pump on an O-360-A1A with a carb? I set my warning limits on the EIS on my former RV-6 (N601RV) at 8 psi for the upper limit, and the owner is seeing 8.1-8.2 and a warning light. I think this is OK, but not sure, and I don't know what the upper limit would be. He can re-set the warning light threshold to get rid of the light, but we need to know what's normal. I replaced the fuel pump and required by and AD a few years ago, before I sold it, but don't think I ever had this warning. It is now based in Reno, so is normally flying at a higher altitude - not sure if that affects it or not. I would check my Lycoming overhaul manual if I was at home, but I'm stuck in NJ for a few days and would appreciate any advice/info.
Thanks,
Scott
