I got a fuel pressure gauge a while back that sits on top of the fuel filter.
When I first got it,it seemed like the fuel system would always be pressurized for days without the car being run.
But now the fuel system completely depressurizes after about 10 minutes.
I may be wrong and it didn't actually stay pressurized for days but I could swear it did.

So is it supposed to stay pressurized or is it normal to depressurize so quickly?

 

mine loses presure after i turn it off i hava thet gauge also

 

I wouldn't worry about it. I think the new information that you have from your guage is making you paranoid

I've seen the pressure on mine hang around for a while or drop off fairly quickly. It is one of the last things I worry about.

 

^^^ mine does the same thing... Worry when it drops low when the cars on op

 

Well I thought it might mean there was something wrong with the fuel return valve but I guess its ok as long as the car runs well..thanks
