does any one know why the vacuum line going to the fuel pressure regulator on the fuel rail would be popping off randomly? my jeep doesnt run any different when it comes off but i cant imagine its good for it to be disconnected. please help its starting to irritate me

 

You might need to replace that little rubber piece that attaches to the regulator. Rubber will stretch over time.

 

I put all new vacuum lines on it tho

 

Any gas in the line/fuel pressure regulator?
