I was just out side testing my fuel pressure to make sure I didn't have a leaking regulator on my 98 tahoe 5.7
Everything seems fine but just wanted to see if some one could verify fuel pressure for me. Here is what I got. It's also below 40 deg out side and this was a cold test followed by a start up and idle. I did not do anything except hook up my gauge.
cold batt
key cylce with no start showed, 56 to 57 while pump was runing and 48 to 50 after pump shut off and held the pressure for over 5 min no problem.
Cold start up up to 58 and then held at idle at 50 to 53. slight blips of the throtle showed a jump to 56 to 58 (no hard rev's) After shut off of engine pump cycled again and showed 62 and then after pump shut off held at 53 to 55.
If someone can just verify for me that this is the range I should see that would be great. I read it somewhere before and that these sound like the numbers I should see but I also have 4 different FI cars and get them mixed up some times.

Oh and I forgot I have 160k on this thing
