Hi.
When I switch the car to the ON position the fuel pressure goes up to 42psi while the fuel pump is energizing. As soon as the fuel pump switch of again the fuel pressure drop to 22 within 5 seconds. After that it start to drop more slowly. (2psi per minute) What type of valves is there in the fuel system and how can I test them. I see the fuel pypes are steel so I cant blank them off.
Thanks
