I'm wanting to put a set of Fuel Rails on my car, I know there are a couple of companies that make them. Some say you need adaptors, etc. What is needed? Are there any that come ready to bolt on an LS1? I know there is:
LS1Speed
Aeromotive
Nasty
Any others?

FAST also makes fuel rails. They do need about $150 in fittings.

Sad but true - most of the time the fittings/SS hose runs the same price, if not more than, the rails themselves. :eyes:

Nate @ Nasty Performance has a nice complete fitting/hose kit to go direct from your stock metal lines.

Do you have a closer picture of what your rails look like? What colors can you get on them?

Has anyone dealt with the trick flow fuel rails. Will these be a direct fit.

They are polished but I can powder coat them any color you want.

How much extra to powder coat? Will these affect my mileage, not that it really matters, at this point just curious.

Not trying to hijack the thread...but what's the limitation on the stock rails?

Nasty N8

Stock rails will feed about 600rwhp. These rails will not change milage. and most colors to coat are $15

Why should I buy one over the other?

They are all pretty much similar in design and I think all use the same internal fuel passage diameter. So your choice pretty much depends on price, and finish options available that are what you want...

I went with the Fast Rails, I had no idea that the fittings and hoses would run approx $150 as davered00ss mentioned. If you know someone with left over #6 and #8 braided lines you can save a little since they only sell it by the 3ft sections. you'll only need 8 inches of each.

this maybe a dumb question and sorry to hijack but can you gety a fuel pressure gauge on stock fuel rail or do the braided steel line on stock rails?

I just purchased the fuel rail kit & install kit from LS1 Speed.

Everything bolted on okay enough, and I got all the braided lines/fittings assembled.

My question is tho, the end of the fuel rail, on the pass side/front.
The end of that rail kicks up right behind where the bracket is for the Throttle cable & Cruise control cable.

I was supplied a plug, which would 'barely' make the whole thing fit in that area.

But if I wanted to (and I do), attach a fuel pressure gauge, and other kind of fitting would interfere with that bracket.

Any tips?

Never heard of anyone having that problem? If you look up to CompTA's FAST fuel rails you can see that he has a FPG installed using a straight fitting and it clears the bracket. I want to use a 90 deg fitting so the FPG can be read from the side of the car.

Unless the LS1Speed rails are different? Allthough I can't see how they could be to far different as they still have to line up with the manifold mounting points and the injectors?

Some gauges will not clear the area...and mine is actually pretty close. We tried one or two different ones before we got that one to fit properly.

FAST should be selling the gauge that you see in my picture and also the install kit for the rails very soon. I suggest giving them a call sometime this week and asking. I'm not sure if or when it will be available, as I'm not on the sales side of things. :)

The LS1 rails line up okay enough with the fuel injectors and 4 bolt points, no problem.

But I think the rail itself, is just longer enough (longer than stock) where it comes so very close up behind the bracket.

In CompTA's, it looks like his rail is actually more towards to outer edge, and clearing the bracket easier.

Maybe I can modify the bracket to get some more room, for right now, there is no way I could get a straight adaptor in there.

if you look at my pics I used a I used a fitting that allows you to view from anywhere on the car- its facing up. This setup would allow you the option to mount a larger guage and clear the throttle cable.
