    My pressure was running low right at 20PSI I don't know what the pressure is now because I needed to take the pressure gauge back to Autozone to be able to buy the new pump. They make you buy the gauge set for $150.00 and give you your money back when you return it. I'm going to work on it today I'll let you know what happens. The truck is running great and the service engine light has not come on.

    I must be old, it's Bain that has the high pressure. My eyes keep playing tricks on me. I don't know why I see what I see. Anyway glad your up and running right.

    My understanding is that the part on the fuel rail is a dampener, not a regulator. The dampener absorbs some of the abrupt pressure changes, but wouldn't actually limit a continual high pressure situation. Please tell me I'm wrong because that makes the job much easier than dropping the fuel tank!

    Also, congrats on fixing your issue!

    Fuel pressure regulator is part of the pump unfortunately. With the high pressure it sounds like a failing regulator, but be sure. You might want to pick the brain of your local shop that knows the vehicle. But it sure sounds like it. Funny thing is when you look on Rock Auto, some show the attached regulator, some don't. I'd go by dealer and get an exploded picture of the pump and adjacent parts just to be sure.

    Got the new pump installed everything works ok. The truck has a lot more power then before running great and no service light. Thanks for all the help everyone.
