    K-Series Fuel Rail by Acuity Instruments

    Whether upgrading for additional fuel delivery needs, to run upgraded fuel lines, or to simply clean up your engine bay, ACUiTY's K-Series High-Flow Fuel Rail is the most versatile and refined solution available.

    With it's 1/8 NPT port on top, -8 o-ring boss (ORB) ports on both ends and another -8 ORB port located at the middle of the rail, there are a variety of ways you can set the rail up for your car (see "Fitment Info" for application-specific fitting requirements). Each rail is constructed from 6061-T6 aluminum and has a satin-texture, anodized finish with laser-etched technical info and logos.

    Among the rails' other features are countersunk mounting screw holes and supplied class 10.9+ hardware to replace the OEM studs. Each rail is also supplied with a stainless steel 1/8 NPT plug in case a top-mounted fuel pressure gauge is used. The end locations for the -8 ORB ports have been specifically machined to help reduce the likelihood of wrench damage to the rail's cosmetic finish during installation. As an added bonus rarely found on aftermarket rails, the rail allows the end-user to retain the OEM injector clips if you wish, just for some added peace of mind.

    Features

    • 15mm (0.59") bore supports 1000+hp
    • 1/8 NPT gauge port
    • -8 ORB center-feed port for tucked fuel lines
    • -8 ORB end ports for OEM, side-feed, or return setups
    • 6061-T6 billet aluminum construction
    • Available in multiple satin finishes
    • Includes class 10.9 zinc-plated mounting hardware

    Please Note: Tons of possible configurations (using optional fittings, sold separately).

    Applications

    • 2001 - 2015 Honda Civic Si
    • 2002 - 2006 Acura RSX
    • 2002 - 2006 Acura RSX Type-S

    1.) All MAPerformance in-house fabricated parts include a Limited Lifetime Warranty for the Original Purchaser. This warranty only applies to the original purchaser and is non-transferrable.

MAPerformance will not be held responsible for additional costs due to the failure of a product (cost of sale, towing, labor, etc.). Warranty claims must be submitted to MAPerformance for review.

    3.) You must create a support ticket to acquire your return authorization number prior to returning the product.

    4.) Warranty claims will not be honored if the product was not purchased through an approved dealer.
