no pressure release valve
there should be a valve on the fuel rail on the engine that you release the pressure, it looks just like a tire valve.
The purpose of a pressure relief valve in a geyser is to release the pressure created inside due to evaporation of water.
To release the excess pressure from its upstream.
Your meaning is unclear. Your system will already have pressure switch, -why would you need a pressure valve?- or are you unaware of the difference between a valve and a switch.
More to the point, where is the Impala at the pressure relief valve, right? Try the local Oriental Massage parlor.
No, not usually.
That would depend on which part of the system the RELIEF valve is located
It is what it is, one blows pressure out and the other simply releases it
there is a valve, kinda like tire air valve, with a green cap on it to the drivers side of the intake near the throttle that you can open and depress to release in line fuel pressure !
You close the valve a little. -If that is not what you wanted, then please explain more next time.
On the fuel rail there is a cap and under it is a schrader valve. Depress the schrader valve.
