how fast should d-jet pressure leak down?, 75 2.0 : is this too fast? Options

10 psi/15 minutes so down from @30 to 0 in 45 minutes.

Went for drive today, have been running really good all week to work but this morning almost didn't start, heavy smell of gas so pretty sure one was leeking. 70 degrees so warmest morning all week.
just wondering if anyone else has watched theirs to see what would be normal.
I had my other set of injectors original to the car- out a few years ago and just sent them in and had them flow tested, and we're within 1% of each other so I'm going to put them back in. They are the metal body ones. The ones I've been running I put in 3 years ago and they were brand new from Otto venice, but plastic not metal like original ones.

Btw the rough start seem and rough idle lasted about 2-3 minutes and ran fine after that.
Also - I only run no ethanol gas. All gas hoses replaced a couple years ago. Filter and tank sock were new then too.

Are you still running a 3 port stock fuel pump or did you put in a new 2 port? I think the 3 ports had some sort of check valve that helped keep pressure in system longer....?
I don't think most 2 ports pumps have that....although I believe one could get a check valve fitting. I had issues with my old 3 port pump where the pressure would drop down after shutting the engine off....would cause problems when I restarted later. Of course, I also had some fuel hose kinks contributing as well. What you're seeing doesn't sound too bad for drop off of system pressure.
