How to disconnect fuel rail crossover?

[nathan1larson]

I'm trying to disconnect my crossover from my fuel rails on my 08 sierra but I cant get the metal clips off that hold it in place. I'm sure theres a trick to doing it but I cant figure it out (Its not the same clip design as a 2000-2006). If anyone could tell me how to get them off I'd appreciate that.

DID a quick Google search since I'm heading out door and only searched 08 GMC no models but this was the first return I got. Let me know if it works for you or not.

         Do the fuel rails look like this?

No :/ theyre a weird design that's held in by a torx bolt (like those ones) but also has other ways of holding itself in place. I'll upload a picture

Ok so you can see here that they're held in place by 4 tabs on each clip, and it doesnt just slide straight back away from the crossover. The part of the clip that sinks down with the crossover keeps it from going straight back.

  Look pretty simple to me. Just pull that torx bolt out and then bend the metal tabs back enough to slip the retaining bracket off.

By the way, why are you taking that off anyway?

I tried that already but like I said, it doesnt pull off backwards. You can see the clip bends down where the crossover goes into the rail and because of that, it doesnt slide backward.

It's in the way of taking my intake apart to clean it. Needs cleaning because Chevy decided to run the PCV back into the inatke and I have a buildup of oil and some dirt that got in there from the pervious owner. I just want to clean it all out before the dirt/oil slowly gets down into my cylinders

  There are (4) clips that are visible. You bent 2. Bend all 4, and pull the bracket strait up. If the front clips connect under that bracket, just cut it with a pair of dikes.

  Your planning on separating the two halves of the intake plenum? 

 

   Sounds like you need  a catch can.

Yea I plan on investing in one as soon as I'm done fixing the truck. Is there a brand that's more recommended than another or are they all essentially the same thing

Here is a cheap one. Its may or may not have an internal filter. If it doesn't, just make one. Super easy to do.

I have a 1999 Sierra. I don't know these parts very well and what I do know ive learnt from you tube. Can I just buy the crossover or do I have to buy the fuel rail also? Just need to replace the crossover attachment .
