    OK,... looking for answers.
    My engine is a 2010 6.1 all stock. I bought aftermarket fuel rails but when I put them on, the clamps didn't come close to holding them down! Do I have some oddball injectors? The stock fuel rails were tight.
    I hate to take meat off of my clamp stands to make them tight. What's the deal? 20170527_161748.jpg 20170527_161758.jpg 20170527_161721.jpg

    Looks to be a bad design on those holddown clamps. Who's rail kit is it?

    I'm not going to say yet. I don't think it's a bad design and there are several sets out there being used. I think that either I have short injectors (don't know if there is a shorter injector) or the vendor may have got a bad batch of clamps from the supplier.....
    I'm just feeling this out. I'll make the rails work because they really are nice but I'm trying to figure out the problem before I make any mods.
    FWIW, my engine is a 2010 6.1 from Cleaveland Power and Performance with 17k on the odometer. All stock so far.

    Have you contacted the MFG to see if you got the right parts? You could have either got bad parts or the wrong parts. Most vendors let the customer be the "incoming inspection".

    There is no right or wrong parts as this is the only set they have. They say that the set fits my engine and they have had no problems before. They are they ones that suggested that maybe I got some odd ball injectors and they are trying to figure it out themselves.
    It's a mystery....

    I've never seen or heard of "short" injectors. I'm guessing it's bad clamps or the fuel rails were drilled too deep.

    Never thought about the rail being drilled too deep. Makes sense though.

      Morning fellas, I'll Jump in here before this gets out of hand.
      These are my Rails, and I've been communicating with Dragger 40 (standup guy) about what the deal is with fitment on a 6.1, vs a 5.7 or 6.4
      Pace Performance Gen III Hemi Billet Aluminum Fuel Rail Kit - HEMIRAIL-K


      From my research, and our testing, I'm coming to the conclusion that the aluminum 6.1 intakes have a slightly taller clamp stand, and its actually angled backwards slightly. Where the new eagle and apache with the plastic intakes, are minimally shorter, and parallel to the ground.

      So in the 50 or so sets of these i have sold, apparently they all went on engines with plastic intakes, or the guys with 6.1's never bothered to call back and make the issue known.

      the "simple" fix for the 6.1 guys would be to purchase conduit clamps (like the bbk use) that can be bent and tweaked to make up the minor height difference.

      these are LITERALLY what the BBK come with. I always thought they looked jankey, and thats why I designed our kit with heavy duty, Billet aluminum clamps.
      upload_2017-5-31_8-12-35.png

      In doing that, I apparently took the "flex" out of the clamps that the other MFG's have with their steel clamps.

      So long story short...

      If you have an eagle or apache, our clamps work great, and are superior IMO to conduit clamps...or pot metal.

      But if you have a 6.1, or an aftermarket intake, you can get ahold of the steel, (tweakable) clamps to make up the minor height difference.

      If you want these for a 6.1, I'll gladly sell the rails by themselves.

      Dragger40 is welcome to get with me for a replacement set of clamps like the ones above, or send them back for a refund since I fully admit that I initially listed them for the 6.1 w/o noticing the clamp stands.

      sorry for the confusion Dragger! appears this one is on me!

      Wanted to clear this up early because these are really Quality kits, nicer than the others on the market, and they are made right here in Youngstown Ohio from Billet Aluminum.

        Hey Johnny, thanks for taking the time to figure this out and for staying in touch.
        I will probably mill down my stands and use the billet clamps because, as you say... they are a hell of alot nicer than some janky clamp. I just wanted to make sure that I didn't have some obscure bastard child from Ma Mopar.
        For anyone thinking about using these rails.... they really are a nice set!

          How about a cool little milled spacer for the 6.1's. Couldnt be that tough to do so as to keep the quality of the original clamps. And yeah, the conduit clamps look cheap....

          the 6.1 has taller stands...so a spacer would only make the pictured issue more exaggerated on the 6.1. Next time we run the clamps i'll look into making the clamps for both designs, But that'll be a ways out, unless I sell a ton of these in the mean time. The 6.1 is pretty sparse in comparison to the plastic intake engines, So I can't re-tool to support the sale of one pair of rails.
