TBI project.

Hello everyone,
I am in the middle of adding a Vacuum adjustable Fuel pressure regulator, 1" Throttle body spacer and injector spacer.
I want to make new fuel lines so that I don't have to tweek the original ones. Are there any adapters available to change from the stock fitting to a 45* flare fitting or a tool that can make the factory "flare," whatever it is called? I've done a search on this and have found nothing yet.
Thanks.

You can convert to stainless steel brake lines which give you more flexability and overall ease of use. YOU may want to vary your wrod choice when searching. Alos, search under z28boy. I belive he has a parts run down on his site.

Z28boys write-up is good. I had some problems finding a couple of the parts he mentioned. When I get a chance, I'll grab part #'s and pictures of mine.

You know, I have been to z28 boy's site before. I just never got to that article. That should do the trick. With some aluminum tubing I should be able to keep a stock look. Most of the fittings will be hidden anyway.
I kind of wish that I had found that article sooner. I bought one of the fuel pressure gauge adapters from CFM-tech, which is a great part, but I will have to mount the gauge remotely because it will not fit under my air cleaner because I have modified it so that it will fit without that spacer ring thingy. With the AN fittings I can mount it right to the fitting, similar to the way that z28boy mounted his.
Thanks for the link. I will start looking for all of the pieces soon.

I just found a tool that can make the factory flares. Check it out if you want. It is only $425.00.

I think I will stick with the AN fittings for now but it is good to know that there is something available.
