Tank to Engine Fuel Line Kit For a '68 to '72 Chevelle

Note: The instructions below are for the "68 to "72 Chevelle, but the same procedures will apply in many other vehicles such as Pontiac GTO - Olds Cutlass - Buicks Ect.

This Fuel Line Kit is designed for quick easy installation and trouble free performance. It comes with everything you need to plumb your "68 to "72 Chevelle. The Filter Kit pictured is not part of the Kit, but can be purchased separately from Street & Performance. Each part is clearly marked and all Kits come with photos and detailed instructions for whatever GM fuel injected engine you have chosen. These lines have been pressure tested and blown out before shipping, but please blow or flush lines again before installation begins.
Passenger side fuel line. Pass the tank connection end of your return line over your new transmission support and behind the old support bracket in the open part of the frame. Move the line to the rear enclosed part of the frame and go thru the opening in the top and continue pushing the line over the top of the rear wheel well until the tube nut is visible in the 1 1/8" diameter hole behind the rear end.
Using needle nose pliers, reach thru the hole and pull the flex line through until the hard stainless lines lit neatly into the open part of your frame in the center of the vehicle. Slide the rubber gromet over the rear flex hose and install in the hole around your flex line. Use 4 of the 3/8" single tube clamps to secure your hard line to the frame rail.
 Pass the front end of your return line up into the engine compartment and install on your fuel rail. DO NOT disassemble the compression fitting. Just slide it onto your fuel rail until the tube bottoms in the fitting. Hold the fitting body with a back up wrench and tighten tile tube nut 1 1/4 turns. A complete set of instructions for these fittings is included in this kit.
Follow the same procedure for your driver side supply line and connect the 90 degree compression fitting to your fuel rail. Secure the 2 front flex lines to your frame or firewall with the clamps provided. Keep them away from your exhaust and moving parts that may damage them. Select a safe and accessable location for your fuel filter in front of your fuel tank where it will not be damaged by up and down movement of rear end components or heat from your exhaust Make sure your 2 hoses will reach this location and your tank connection.
Install the (2) two 90 degree 1/4 pipe x 06 AN fittings in your fuel tank. Use Teflon paste or tape on the pipe threads and any type oil on the male flare ends to insure proper sealing. Connect the short rear hose to the PU connection on the tank, connect the return line on the passengers side to the RTN marked fitting and raise the tank into position and install your tank straps. Attach the drivers side fuel line and the short hose from the tank to the fuel filter (use oil on the male ends of the filter fittings). Secure the slack in the flex hoses to the under side of the body using the clamps provided. Leak check your entire system before attempting to start your vehicle.

Depending on which engine you have selected your fuel pressure required to start your engine will be between 30 and 60 PS1. A fuel pressure gauge available from Street and Performance will be needed to verify proper fuel pressure for starting your engine. Keep in mind that your fuel pump will only run 2 seconds on initial start up. Turning the key on and off a few times will pressurize your system and allow you to .perform a leak check and verify fuel pressure requirements.
