If anyone has any ideas let me know. My fuel pressure was at 35 so I changed the fuel filter and nothing happened. Then I changed the Fuel Regulator and now it will go up to 40psi when I romp on it but stays at 35 at idle. Vaccum is between 12-15psi on the intake. Do I need a fuel pump? Is the best way to put a pump in is lift the bed or drop the tank?

Also, while I was changing my Fuel Pressure reg. the small O-ring on the end dropped into the fuel rail. Is that going to cause problems. Could it get into an injector. What is the best way of getting it out? The O-ring is a little less than 1/4in diameter.
Thanks for all the help.
