Getting ready to install the fuel pressure regulator, I went out and looked at the fuel pressure gauge. it wasn't at 15, the way it seemed to be pegged on the last start-up.

It was at around 9.5. Just sitting there. No electric fuel pump "on"....So, first I pulled the gauge. It *did* move. To 7.5...while it was off. No pressure. There is a screw
at the back I figured was an adjusting screw. I adjusted it. No dice.

Couldn't get another one today, so I installed the fuel pressure regulator, hard and soft lines. Screwed the fuel pressure gauge back in. Fixed a couple of trouble spots.

I think it showed 12 when adjusted all the way out ("most clogged") while the ignition was on and the motor was not running. When I started it up, the gauge reads "9".
Guess I better get a new gauge.
