Getting the rest pressure time is like pulling teeth. I far exceed the 10 min 1.7 bar value. So if at 20 min if I have zero PSI rest pressure are you saying I won't get vapor lock and the car should start? In the summer my car will not start between 3 an 4 hours after it is shut off. Three hous happens to be when my rest pressure drops to zero PSI. Now if I go out and prime the system by turning the key to on, at 1 to 2 hours after shutdown....this keeps pressure in the system for four to five hours and it will start right up no problems at the 3 to 4 hour time that was the problem. Now you see why I want to know if it should be holding rest pressure for longer than 3 hours. --- In dmcnews@xxxxxxxxxxxxxxx, "David Teitelbaum" <jtrealty@...> wrote: > > I don't find it useless.
