I put a fuel pressure gauge on mine a few months back and she runs around 7 PSI. This cool weather around 30 degrees will show about 3 PSI until after a few miles or about 20 mins and the pressure will come back up to 7 PSI. Its like the fuel warms up. I'v got almost 40,000 miles right now. I replaced the fuel filter and no help. I really dont like the idea of putting the pump in the tank and will talk to Glazier if it gets any worse.
