AN fittings for fuel....

[PSID6]

Does anyone know where you can buy AN fittings to our metric fuel rail and return out of the regulator?

Racetronix will have what you need. They are a supporting vendor on the board.

Thank you sir

Don't use the cheap blue/red aluminum ones. I've had two go bad within months and leak fuel. Will only use stainless from now on http://shop.hoseandfittings.com/cat...on_id=f4bd1c860bf35e2543bbeed490d5c871&LINE=1

On your regulator? We use the aluminum blue and red fittings all the time on our cars and do have any issues. Now if you crank on them like lug nuts you will ruin them quickly.

I had two go bad on my fuel rail. Just used them to attach the fuel pressure gauge. I was careful not to over tighten them. first one lasted a year, second one about a week.

So I went on Racetronix site but I still don't know what the thread pitch is? Should I be ordering the 16*1.5 or 14*1.5 thread
I am wanting to go from the factory supply and return lines right at the frame rail -8 from the supply to the fuel rail and -6 from the reg down to the return.

The fitting on the rail for feed is M16 X 1.5 pitch. The fitting on the regulator is M14 x 1.5 pitch. You might verify the regulator if yours is anything other than stock. If you have the stock return line right now, it is M14 x 1.5 pitch.

Absolutely SUPERB write up here from sakudog on his fuel line replacement.

Awesome thanks man

Sakudog doesn't mention the cost of all the fuel line upgrades and if I were to go through all that trouble and expense I would surely go to a 8an feed line not a puny 6an one.

I think I'm just not able to picture this... I'm trying to find a coupling from the rail to my new jegs fuel pressure gauge. So which thread pitch is referring to the threads on the rail?

M16 x 1.5 on the rail

Great, now reading it over, it makes much more sense

If you are talking about the test port on the rail (on the driver's side that has the schrader valve in it), it is -4AN. I'm just assuming that's the one you're talking about because that's where many install a gauge.

If I had it to do over again, i would run a hose from the test port over to the fender well to mount my gauge and FP transducer in order to isolate them from vibration. That may very well have contributed to the failure of your previous gauge.

If that is the part of the rail that you're talking about, i know casper's sells an adaptor fitting that goes from -4AN to 1/8" NPT. I got one from there once and stripped it during install.
