•DESCRIPTION: Aluminum Fuel Rail Kit #3638 is designed to be used with the Edelbrock Victor Jr. LS1 EFI Intake
Manifold #29085. It is designed to be used with compact injectors with a 1.50” O-ring to O-ring length, such as our
high impedance Edelbrock Pico injectors, or standard height injectors with a 2.50” o-ring to o-ring spacing such as our
Edelbrock Mototron injectors.. See our catalog under “EFI Replacement Parts” for details. This fuel rail kit may also
be purchased with the Edelbrock Victor Jr. LS1 EFI Intake manifold (#29085) under catalog #29086. It may also be
used in custom applications where manifold #29085 is not being used.
•FUEL RAIL KIT: Install fuel rail kit and your injectors using the included 1/4”-20 nuts and bolts. Apply an o-ring
assembly lube to the injector o-rings before installing them into the manifold and fuel rails. Brake system assembly
lube works well. Make sure that the o-rings of the injectors create a complete seal with the fuel rail and the intake
manifold to prevent any air or fuel leaks
Kit includes the following:
❑2 - Machined fuel rail extrusions (fuel rail ends tapped for 3/8" pipe)
❑4 - Fuel Rail Stand
❑4 - ¼”-20 x 1-¼” Hex Head Bolt
❑4 - ¼”-20 Hex Nut
❑8 - ¼” AN Washer

•FINAL CHECKS: After finishing assembly, check the following:
❑Check the fit of each injector. They should be able to rotate freely. The O-rings should be fully inside their
respective bores.
❑Activate the fuel pump and fully check the system for any leaks prior to starting the engine.
