Fuel Pressue slow drop over time - is this acceptable? With key on, no engine running, I have pressure consistently at 41. 2995 Camaro 5.7 LT1. However, the system is slowly leaking somewhere. I have already found and replaced two injectors that were leaking fuel slowly. Here are the time stamps and corresponding pressures after no more injectors are visibly leaking: 9:50 pm 41. 10:04 38. 10:18 37. 10:35 35. 11:00 pm 33 went to bed. Checked it at 7 am this morning and pressure is all the way down to 11 now. Is it physically possible for an injector to leak air and not fuel? Are these pressure drops within acceptable ranges or do I need to keep looking for more leaks? I was getting gas in my oil which is why I am testing in the first place. Thanks!
