Note 1: The female threads machined at each end of the rails is 8AN straight thread (3/4"-16).
Note 2: In most installations using a crossover line, it is necessary to locate the crossover at the front of the rails, using the port plugs at the rear. The crossover line can be moved to the rear of the rails, if clearance on your vehicle is sufficient.
The Metco Motorsports fuel rails for the GM LS1 application are precision-machined from billet aluminum, not commonly available extruded rail stock like other fuel rail kits.
Because our rails are CNC-machined from billet, we were able to design them with the largest internal diameter available for this application at 11/16". This large internal volume ensures that the maximum amount of fuel is available at the injector and that pulses and pressure variations are minimized.
The rails are machined with two 1/8" NPT ports at the front of the driver's side rail to allow for the installation of a fuel pressure gauge or sender, to serve as a convenient fuel supply for a nitrous injection system, or both. Stainless steel pipe plugs are included to seal any unused ports.
The rails are clear-anodized for long lasting surface protection, and precision-bent stainless steel mounting brackets with stainless bracket bolts are included.
As shipped, this kit includes the rails with mounting brackets only. For users seeking a plug and play installation, a pre-fabricated fuel line crossover with swivel fittings, a stainless steel adapter for the factory feed line, and AN port plugs for the rear of each rail can be added. These fuel rails are available in the clear-anodized finish only, with black-anodized fittings. Images 4 and 5 (above) show the rails in a with previously-available blue-anodized fittings.
Images 4 & 5 above show the clear-anodized rails with the optional crossover line and fittings, feed line adapter, and pressure gauge. The link below is to an image of the available feed line adapter installed on the driver's side fuel rail:
