    14400 - JEGS Fuel Rails for OE-Style LS Engine Intakes is rated 4.3 out of 5 by 16.
    Rated 5 out of 5 by from Easy install I ordered these for my '04 GTO. The factory rails were corroded and ugly ! The kit gives you versatility by having your crossover at the front or the rear of the rails. The supply line can connect to either end as well. They look great, and install was easy. My stock injectors popped right in.

    Rated 5 out of 5 by from Great Fuel Rail for LS Swap I bought this about a month or so ago for a project car my dad and I have been working on for a few years. It is a LS-swap in a 66 GTO. Since we put the motor in we had been having issues of losing fuel pressure at wide open throttle. This Fuel rail 100% corrected the issues we were having with the stock fuel rail in our swap and was much more reasonably priced than others. High Quality parts. Bolted right on our stock ls1 intake.

    Rated 4 out of 5 by from Good Great quality, but it didnt come with everything I needed for the complete install i had to buy seperate parts.

    Rated 4 out of 5 by from Good item Bought this two weeks to update my stock rails on my fast 90. It fit great but it did require to take a little bit off the intake because the rails would touch and not seat properly. But remember this is for a stock LS1 or LS6 intake but like I said with some small modifications they fit. Very well-made product.

    Rated 3 out of 5 by from Difficult fit for c5 corvette Bought these about a month ago and thought they would be super simple but the clearance between the back of the rail and firewall is very tight and difficult to get a tight 90 degree an fitting to fit without trimming and the coating on the rails scratches very easy but overall functionality is great

    hello i have a 2005 5.3 and i am putting a Ls1 intake and adding these fuel rails. i was going to buy ls1 injectors so i don't have to use the stock ones with spacers .will they work with my harness. or should i just use stock 5.3 injectors with spacers?

    Asked by: TEEsCamaroLSX
    You can use your stock injectors unless you are adding more power to the engine, then you would need a larger injector.
