Introduction & Installation Notes
A little bit of information to make sure you have the right parts before you get started!
Before getting started we need to set up your fuel rail for with the correct fittings for
you fuel lines. This install guide is targeted at installing this fuel rail on a non k-swap vehicle.
If you are installing this on a k-swap vehicle, the set up of your fuel rail will be outlined in the
fuel line kit you have.
Port A: Optional to run a fuel pressure gauge here,. If you are not installing a gauge , install the stainless steel NPT plug here. Be sure to place fuel-safe sealant on the threads
whether you are running a gauge or the plug.
Port B: -8 to 5/16 quick disconnect union.
Port C: -8 AN plug.
Port D: -8 AN plug.
When set up with the correct fittings your fuel rail should appear as the one below.

cover is held on with rubber
grommets.
STEP 2A:
Unplug all (4) injector wires from
the injectors and using your
10mm socket again, remove the
ground connection from the intake manifold as illustrated in FIG
