    These billet aluminum fuel rails make a great addition to any GM LS1, LS2, LS3, LS6, LS7 or L99 engine bay. They are direct bolt-on rails for OE-style intake manifolds and are machined from solid aluminum with the undersides relieved for ultimate weight savings. The aluminum is finished in a high-gloss anodizing making it both durable and good-looking. Fuel rail kits come with matching hand-polished fittings and a stainless braided hose. Both the fuel rail set and kit come with -6 to 3/4-16 O-ring adapters but are machined to also accept -8 O-ring fittings (available separately) to fully take advantage of the 5/8'' diameter fuel passage.

    Fuel Rail Set:

    • Fits LS1, LS2, LS3, LS6, LS7 and L99 OE-style intakes
    • High fuel flow
    • Includes (4) -6 to 3/4-16 O-ring adapters
    • Machined to accept -8 O-ring adapters (sold separately)

    Complete Kit:

    • Fits LS1, LS2, LS3, LS6, LS7 and L99 OE-style intakes
    • High fuel flow
    • Includes (4) -6 to 3/4-16 O-ring adapters
    • Machined to accept -8 O-ring adapters (sold separately)
    • 6 feet of -6 braided hose
    • (4) -6 90° and (2) -6 straight hose ends

    Rated 2 out of 5 by from Wow what a pain Coolness can be hard and this proves it. For a rookie at cutting braided line it helps to wrap it in tape before you cut it. Thor’s hammer and Excalibur will cut the Holley line it is tough. For the 2010 to 2015 camaro the first issue is they recommend an adapter to connect the stock hose with the GM quick disconnect. Oh an by the way you will need a fuel line quick disconnect tool not include. 3/8 size under $10 at Autozone. The stock GM fuel line you would connect the Holley adapter into is designed to attach to the middle of the old fuel rail. The Holley connects at the ends so this isn’t going to work on a 2010 to 2015 Camaro because most of the line is hardline. So I just had to cut the stock hose at the rubber to metal translation and attach the rubber side to a Holley fitting. Doesn’t leak which is a good sign. Razor knife cuts the OEM hose fine. So this change allowed me to feed rails from the back. I did utilize the plug from the kit to plug the back drivers side Holley rail so yeah you will need part of that quick disconnect kit. Then there is the final thing that is going to drive you nuts. There are two brackets at the back of the OEM fuel rails you must remove. However the engineers at GM used extremely long bolts to hold down the intake manifold and utilized those to hold these brackets down. Only issue is they hit the underside of the cowl and therefore can not be removed unless you pull the motor. Or possibly remove all the intake manifold bolts and see if you can slide the manifold forward. Or get out your multifunction vibrating cutter and carefully cut off the brackets without destroying the bolts. Side note this is what I did. (side note I was an engineer at GM powertrain) I finally after about 8 hours got it together and will smell of fuel and tears. However, I have a really cool Holley sticker to put on my ride. Oh wait no I don’t they apparently don’t include those anymore. The valve cover pictures are Holley as well and they went easy.
