This Hybrid Racing Tucked Fuel Line is designed for RSX, EP3 and 8th Gen Civic Si owners looking for a reliable and durable way to tuck and clean up the appearance of your fuel feed line.

This kit replaces the OEM rubber lines with a -6AN braided line. It also replaces the plastic connectors with durable aluminum connections that will stand the test of time. The line connects to the OEM hard line at the firewall using a specially designed quick disconnect fitting. You can attach the line to the fuel rail using one of the AN fittings supplied with the line. Once installed, the new line will route between your number 2 and 3 runners and neatly hug the transmission as it snakes its way to the hard line at the firewall, giving your engine bay a cleaner, less cluttered appearance.

Unfortunately, stock fuel rails are not invited to the party as the OEM fuel rail lacks the proper ports for the new line. This kit is designed to work in conjunction with the Hybrid Racing Fuel Rail. If you order a Hybrid Racing Fuel Rail and this kit, you'll have everything you need to get your tucked fuel system setup. This kit will also work with any other aftermarket rail featuring a center port, although additional adapters may be required.

Simple. Clean. Tucked.

FUEL RAIL

Hybrid Racing fuel rails are made from 6061 aluminum with T6 heat treatment and feature a durable anodized finish with a laser-etched logo ensuring that your engine bay looks fresh and your engine stays fed!

Each rail includes a 1/8" NPT hole that allows you to mount a fuel pressure gauge directly to your fuel rail. This puts the fuel pressure gauge in a spot that's easily visible, so you don't have to poke around in the engine bay just to see if you have fuel pressure. All of the ports can accept a -8 ORB fitting in the inlet(s) and outlet allowing you to run either -6 or -8 AN fuel lines.

The other detail that should stand out is the option for plugging the side inlet and outlet to allow you to run your fuel line to a centrally located -8 ORB fitting. This is positioned so that the fuel line can pass between the middle two cylinder intake runners (depending on your intake manifold.) This is an excellent option for anyone looking to tuck their wires and lines.

What intake manifolds is this rail compatible with?
This rail has been shown to mount to the PRB, RBC, and RBB intake manifolds without needing any modifications. Any aftermarket intake manifolds that share the same fuel rail mounting points as the PRB, RBC, or RBB should also accept this rail.

FUEL PRESSURE GAUGE

The precision-engineered Hybrid Racing fuel pressure gauge provides accurate fuel pressure readings that are critical for highly sophisticated fuel systems. They resist the most severe vibrations, offer a 0-100 psi reading, and are housed in an all-steel case with a matte black finish and a Hybrid Racing Green needle.

No OEM Honda comes with a fuel pressure gauge and without one, you can not monitor or set your fuel pressure. With a fuel pressure gauge and a fuel pressure regulator, you can accurately dial in the amount of fuel your engine gets to ensure maximum performance. In the case of a K-swap, you will need a fuel pressure gauge so that you can accurately set your fuel pressure around 50-52 psi. The gauge has two subtle marks to help you line up your fuel pressure when running a K-Series engine.
