Aftermarket fuel rail options?

Are there any aftermarket fuel rails available that are made to accept the stock injectors? Thinking of replacing this ugly cumbersome unit. Already have an afpr. Thanks.
 
You know...I do recall that conversation. But vaguely. In any event, that may be too much of a hit and miss. I'd rather if I could get one CNC billet machined. Ah well, a guy can hope.
 
This company should be able to sell it to you separately if they still sell these.

Awesome find. I'll check them out and see.
 
I just received my fuel rail from rzcrewgarage. I will have to compare it to the stock fuel rail when I have a chance. It is nicely crafted cut out on a CNC machine with a 12 mm fuel chamber. I even got in anodized black for not much more. It comes with two set of fittings for both ends (both sides look to be 3/8" npt for rail side). The other end is 6 AN or 1/4 nipple. It does not have a fuel pulse damper and I'm not sure how important that will be with the larger than o.e.m. fuel rail. I did come across a how to build your own fuel rail using this:
https://www.sbpartsdirect.com/product_p/sb-rmr-019.htm (this is one is a 1/2" diameter fuel rail). The same company sells an 8 dash one also which I believe is 5/8" (too big I believe for our small engines). The 1/2" one is the same part as a member was selling on here. If I were making the part the time I would have to put in and the cost for the fittings would be higher then his cost.

However, the rzcrewgarage was nicer made and powder coated for a similar cost. It has a slot built in for adjustment and it was available. The down side is it is slightly smaller at 0.472" and takes over a month to get.

I'll take a look at the o.e.m. fuel pulse damper to see if can be removed and added to the aftermarket rail. I did read a few post that a return style fuel setup had less to worry about fuel pulsating, but Suzuki engineers included it. I'll compare the stock fuel rail diameter with this and make a judgement call on if I think it is needed. I'll post a picture of the rail when I get a chance.
 
hey GT4LIFE.
I know its a couple of years old post but I'm wondering how you got on with the fuel rail?
I'm interested in getting one but concerned about the lack of fuel pulse damper! Any help or advise would be appreciated

Thank you
 
I never installed it. I have the rail in a box, and never test fitted it. I actually forgot about it until seeing your post. I have a spare gti manifold with stock rail in costco toat. When I get a chance I can test fit it to make sure it fits. I found this video by Holley to really help explain dampers. I didn't realize that Holley sells fuel pressure regulators with built in dampers. I know that the two Holley independent dampers would screw into the after market 6-an fuel rail. I don't remember off hand know how the stock fuel damper is attached. I can check to see if it is at all possible to switch over. I doubt it. The Holley ones are expensive at $100 to 150.

 
Thanks for the update and info.
Please keep us up to date if you do get around to fitting or testing. Info on these cars is so hard to find so it’s much appreciated 👍🏼
