Cool fuel rail question....

Hope someone can answer my question

If I buy the holley LS Hi-Flow Fuel Rail Kit http://www.holley.com/534-210.asp

Do i need to buy and do the Fuel Line Conversion kit that JDP Sells or will the holley fuel kit move the fuel line off the intake??

Has anyone installed the Holley kit and if so how hard was it and will i need to do any fabricating??

The directions say this: P/N 534-211 - Adapter kit, required when directly connecting Holley fuel rails to GM factory fuel line quick-connect. Includes (1) 3/4-16 O-ring port plug and (1) -6 to GM quick connect adapter.

Those look pretty sweet. I think I found out what fuel rails I want when I get heads/cam.

Yes, but that part number (534-211) is an "Optional Accessory", so it will ordered separately from the fuel rails.

Yes, that is my interpretation. You will need P/N 534-210 & 534-211.

Do you have a picture of that? I'm just curious myself.

OP what you're lacking is a fitting to get you back to the aluminum fuel line (near the frame rail). Not sure what 534-211 includes or is but essentially what you need is something like this



The bottom 'U' shape unscrews. You slip that under the bottom of the lip on the factory fuel line, slip the threaded part over, and tighten. Now you have a -6 fitting to screw your -6 straight fitting on to from the other kit.

And a word of advice to anyone making fuel lines for these fuel rails...tighten it as much as possible before it makes its way onto the car. Once it's on, if it's leaking, it's tough to get a lot of travel with a wrench back there to go any tighter.

If i get this and the P/N 534-210 & 534-211 then this should be all i need? Will i need a fuel rail tool to help disconnect the fuel lines?

I was reading somewhere about braded fuel lines leaking gas a bit... is that true??

Yes, go to my thread and learn how I eliminated that concern.

You will need to finish the lines, and may need some extra line to fabricate the line from the factory feed to the rear of the rail.

It's not hard to do, all I was saying was to tighten them as much as possible before going on the car, because once the rails are on they are a lot harder to get to. Just take your time and do it cleanly and you'll be fine. We custom make our fuel lines for almost everything and they don't leak.

You will have to remove the intake manifold from the car anyway....just to get the aft bolts out of the factory fuel rails. So...while it's out, just install the new fuel rails and put it back in as a complete intake assembly.

So i will have to remove the whole intake to do this?? Is that a tuff job? I looked at the install directions and it didnt look like it said to remove the intake.

Neb, you need to start on page one of my thread and start reading. My whole purpose for the thread was so that it would be a reference for all members. There's a video in it of how to make lines. There's a link to a step by step on how to remove your intake. I also did research on what lines to use that won't emit gas vapors. If after you've gone through it, if you have any further questions, let me know and I will be glad to help.

It's not difficult! Trust me as I didn't know any of this before I started.

Nathan

There is a black cap on the driver side front end of the fuel rail. Unscrew it and press the Shrader like valve. Put a rag under to prevent fuel spillage.

If you make the braided lines correctly they shouldn't leak.

I made braided fuel hoses for my car, and they don't leak a drop. Also, this would be a good time to relocate those heater hoses that go up over your intake. Maybe your car already has them relocated, I know GM switched to different hoses at some point, but not sure if the 11's got the new hoses or not. Tech AFX has a great illustrated instruction "book" that covers removing those hoses and removing the intake too. If you do have the hoses that go up over the intake, I would suggest replacing them with the later GM hoses that should be available from the dealership parts dept.
