  1. The plate on the motor is a little tough to read but I believe thats what it says. I have the complete vin if that helps. Ill have to mess with the valve and see if I can get it cleared. The truck is a 12 speed 6 wheel short bed
  2. It is a 275 hp cat motor. I changed that cheap fram filter on top of that separator and it made a big difference. I opened the valve after driving for a bit with the truck off and nothing came out at all nothing no fuel or water. With the two new filters them truck runs much better but I still feel its not running at 100%. According to the dash the truck has 320k on it. Also the tach cuts in and out would this cause a perfomance issue or is it strictly for the driver. Also when it would start to break up the engine warning light would come on is there a way to pull codes out of this truck.
  3. No theres no wires going to it at all. I believe its some type of fuel filter or water separator but im unsure
  4. Does anyone know what this fuel filter setup is and anyway to possibly clean it im getting a new filter for the top of it but im unsure of what to do with the setup.
  5. It has a cat motor in it im not sure of the miles. I changed the oil and oil filter. I changed one of the fuel filters today the second will be here tomorrow. Changing the one fuel filter made no change I will hope for the best and change the second tomorrow but both appeared fairly new. In neutral the truck will rev and idle properly. Start driving and about halfway through the gear it starts to breakup and wont rev any higher and you have to upshift to get the rpms down to continue accelerating but it has no power because you cant get into the power curve.
  6. It could have been im not sure though they purchased the company and all the equipment last spring I believe.

  9. Okay you guys were great with the earlier help let see about this. Its a 94 l9000 half way through any gear it starts to buck and lose power and blows some blueish smoke it feels like lose of boost but I cant seem to find any leaks and there is no boost pressure gauge in the truck.
  10. Okay so I was able to locate fuel and oil filters is there any special procedure for changing the fuel filters priming steps or anything I should be aware of before I get involved
