Hot start problems 280 SEL 4,5 1972 - Fuel pressure
My car is hard to start when hot, starts fine if I start just after i have stopped it, but if i wait 15-20 min, then it is hard to start. I want to measure fuel pressure. I have marked some rings in the picture. If the fuel pressure fell (it sholud be about 28,5 psi), is it because of the Regulator (green circle) or Damper (blue circle)? Where do i measure fuel pressure, red or yellow circle or other place? What do i do about the place i disconnect hose from? What do i plug with?
