Introduction

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.

Using a 10 mm socket, remove the two (2) caps nuts holding the cover in place (FIG 1). Once these are removed, pull the cover off. This will take some force. The cover is held on with rubber grommets.
