Two fuel filters. one under the drivers side of the cab, one on top of the motor.
Other filter on the motor is for the oil.
Use OEM only filters. Either the dealer or online. Parts stores generally carry knock offs that don't fit correctly.

and don't forget to take the water separator off the frame and clean that bad boy too! See too many of them get clogged solid with sludge and cause all types of problems. All you need is fuel line disconnect tools, any auto store will have them for under 10 bucks

What should normal boost pressure be?
Filters were changed out and cleaned fuel additive was added ran good for a few days now kind of a dog and rough at start up. Any suggestions?

If the fuel filters didnt help it could be several things but I'd start by checking the egr valve first just to make sure its not stuck open. A stuck open egr valve will cause lots of black smoke and low/no boost on acceleration.
Check the FICM as well.

If the egr valve and FICM are both good, start goin down the checklist.

How would I check the EGR valave and it doesn't do it all the time its spuratic, Dealer said it could be turbo weakness from setting and not getting run truck runs at least three four calls a week so I dont think thats it.
