Tapping The Fuel Rail For Fittings

This is kind of a DIY for the easiest way to thread the rail.
I just got done tapping my rail for a 3/8" NPT fitting. 3/8" is the perfect size to do it because it's just slightly larger than the rail opening, so it takes no effort to thread it. Then you can just screw in a 3/8" NPT to -8 or -6, whatever fitting your regulator will take.
The tap is pretty big and does NOT come in any normal tap and die kit that I've found (Sears, Home Depot, etc.). I had to go to a specialty hose/bolt store to find it, and they charged me $18 for it.
But in the end, I spent $18 for the tap and $6 for the fitting. That still comes out a hell of a lot cheaper than the "fuel rail adapter kits" which run $30 and more!
If you want, you can send me your rail, and I'll tap it for you. Just pay for the shipping which shouldn't be too bad. It's really an easy thing to do though.

Hah, I found your post finally.
LOL
While that's not a bad idea, maybe you should just go get some fuel rails, tap them and offer different sizes to folks?
Anyways, guys, don't forget how important it is to support the people making new parts and such for us.
With the APE kit, you can go back to stock with no worries.

I think it looks WAY cleaner than using those kits, but whatever........

^^^Werd. It's just the crankcase hose. I pulled it back for the pic.
Only the main feed line before the filter. And it's not that restrictive. It'll probably support 450hp easy.Some Hondas run 600whp on stock fuel lines. DSM's almost get that too. But I mainly want to get rid of the rubber fuel hose patch job. I tapped into the stock line for nitrous, and the hard line gets in the way a lot. Kind of makes it safer too.
I'm replacing the main feed line when I get my tank and pump setup done. Soon.......... fing02.gif

you are still limited by the tiny stock hard fuel lines though, arent you?

Huh? You're gonna need to explain what you want a bit better.
I have a pipe fitting on the other end of the rail. Then a hose that connects that to an SX FPR. Then a barb fitting with a fuel hose running back to the stock fuel return line.
