SHIM KIT for FUEL RAIL VALVE
Three ( 3 ) Washers and Separation Tool
|
|
--------------------------------------------------------------------------------------------------------------------------------------------------------
1. Remove the dipstick and 4 bolts holding the plastic cover plate on top of the engine. 2. Using an 11mm wrench remove the 2 clamps holding the EGR tube that crosses in front of the valve cover. You do not have to remove the tube only tilt the tube up towards the front of the truck.
| 
|
3. Using a 10mm socket and wrench, remove the bolt that holds the dipstick tube to the bracket and the 6 bolts that hold the air horn to the manifold. Making sure not to damage the gasket, slide the air horn forward so that you can access the front of the fuel rail.| 4. Remove the 18mm fuel rail valve located on the front of the fuel rail. |  |
| 5. Take valve and thread supplied nut tool onto valve. Then place valve in a vice, clamping down on sides of valve cap. |  |
| 6. Use a wrench to unscrew supplied nut in order to remove valve cap. Be careful to hold end of valve while doing this! It is spring loaded and you don’t want to loose parts! |  |
| 7. Removing metal spring, then insert the 3 supplied metal shims into valve. |  |
8. Replace valve spring and then cap. Note that there are 3 holes in a triangle position on the inside of the valve cap that does not need to be removed from cap and should face towards spring as it did when it was removed,
hole alignment is not necessary. |  |
9. Place valve back in vice, now with a thick piece of cardboard or piece of wood behind valve cap to prevent damage to the valve seal surface. Tighten vice so that the valve cap reenters valve until fully seated. No need to
over-tighten; just tighten until snug. |  |
10. Take a small punch and small hammer and re-apply the 3 factory indentations along the lip where the valve casing covers the valve cap. You may need to loosen the vice slightly to rotate the valve to access all 3 indentations, but do not let the spring push the cap out any! Make sure that the cap stays fully seated in valve while rotating. After doing so loosen the vice and make sure that the valve cap is held by the indentations. | 
|
11. Re-install the fuel valve and tighten it down to 50 ft. lbs.
12. Now you can re-install the air horn, make sure to line up the six holes in the gasket with the bolt holes for the air horn. Also connect the dipstick tube to the bracket on the air horn.
13. Line the EGR tube back up. For easier installation line up one side to its connection, install the clamp but leave it loose enough so you have a little movement to connect the other side. Then fully tighten both sides, once you have both sides lined up correctly.
14. Locate the fuel pressure sensor on the back of the fuel rail close to the fire wall. Plug the factory connector into our harness and our harness
into the fuel pressure sensor.
15. Connect our harness to the Diesel Performance module and mount the Diesel Performance Module in a
location of your choice.
16. Mount the switch in the cab any where you like.
