KOEO should be around 40 psi.... at idle 32ish psi. If you are having a problem and suspect it is fuel delivery, the fuel pressure must be read WHEN the problem is happening.

Thanx Jim, it was the pressure regulator. Although the wife had determined that the truck was pregnant due to the following reasons: It's tempermental, it eats alot, and it smells funny. Thanx again
