Section 3 – Fuel Regulator Installation and Fuel Line Plumbing
3-1. In the vehicle’s engine compartment, mount the supplied fuel pressure regulator in the location established in step 1-
26. Using the supplied mounting bracket as a template, mark the bracket mounting holes and drill to accept a #10
screw.
3-2. With the bracket attached to the regulator, mount the bracket and regulator to the vehicle using two #10 screws, nuts
and lock washers.
3-3. Install two of the supplied AN-10 o-rings on the cutoff side of two AN-10 cutoff to AN-08 reducer union fittings, if not
already installed, and install in each of the AN-10 ports located on the sides of the supplied fuel pressure regulator.
3-4. Install one of the supplied AN-06 o-rings on the cutoff side of the AN-06 cutoff union fitting, if not already installed, and
install in the AN-06 port located on the bottom of the supplied fuel pressure regulator.
3-5. Install two of the supplied AN-08 o-rings on the cutoff side of two AN-08 cutoff union fittings, if not already installed.
3-6. Install one of these AN-08 fittings on the front side of the passenger side fuel rail. On the driver side fuel rail, if there is
adequate clearance between the distributor and the fuel rail, install the second fitting on the front side as well, if there
is not clearance install the second fitting in the AN-08 port located on the bottom center of the fuel rail.
3-7. Starting from the fuel rails, plan a route to run an AN-08 supply line from each fuel rail to each side of the regulator,
see figure 3-1. Cut the two supply lines to the determined length and install the AN-08 hose ends, as detailed in
Section 4.
Note: Be sure to route all fuel lines clear of any moving suspension or drivetrain components and any exhaust
components! Protect fuel lines from abrasion and road obstructions or debris.
3-8. Using the above steel braided hose assemblies, connect one end to the side of the fuel pressure regulator and the
other end to the fuel rails, as shown in figure 3-1, and tighten.
Figure 3-1
3-9. In the vehicle’s engine compartment, find a suitable mounting location near the fuel rails for the supplied Y-Block,
using the Y-block as a template, mark the mounting holes and drill to accept a #10 screw.
3-10. Attach the Y-block to the vehicle using two #10 screws, nuts and lock washers.
3-11. Install two of the supplied AN-08 o-rings on the cutoff side of two AN-08 cutoff union fittings, if not already installed,
and install in each of the AN-08 ports located on the supplied Y-Block. Install one of the supplied AN-10 o-rings on
the cutoff side of the AN-10 to AN-08 reducer union fitting, if not already installed, and install in the AN-10 port
located on the supplied Y-Block.
3-12. Starting from the fuel rails, plan a route to run an AN-08 supply line from each fuel rail to each side of the Y-block,
see figure 3-2. Cut the two supply lines to the determined length and install the AN-08 hose ends, as detailed in
Section 4.
