I need to know where the fitting is to hook up a fuel pressure gage on my 1999 Tahoe with a 5.7L engine and 150K miles. I looked around but I did not see it. I have a no start condition and want to check the fuel pressure before I look at anything else. Thanks in advance for the help.

looks like it's close to the firewall...
is a 97 model with the same engine size the same?

Thanks, this is perfect it points me in the right direction. I'll report back what I find. I've got something strange going on.
