2002 Ecotec Fuel Rail - Hahn Billet Rail Adapter Installation
Saturday, September 24, 2011 6:44 AM
Hey,

I decided to purchase this adapter from Hahn in order to mount the AFPR on the rail itself. Bought the adapter and it arrived the next day for $65. I then decided to ask Bill Hahn if he could piece together the entire AFPR kit (fittings, gauge, hoses etc). Everything I would need basically to "bolt" it right on my fuel rail; he did. and charged $330.

I have a new Aeromotive regulator (Billet and Red). See my photobucket link below for reference.

I do not know what connects to the adapter and if I have to remove the two fuel lines that go into the fuel rail. Also, do I need a special crimper to crimp down the brass fitting on the 90 degree bends?

Can someone please help? As soon as I get info, I'll be installing it.

Thanks

Anyone? Bill sent me a diagram. It shows OUT from adapter to IN on FPR. OUT from FPR to IN on adapter. If that's all I have to do then easy. But, I don't see where I would use the braided line with fitting that connects to FPR and the thinner fuel hose. I would simply cut the larger diameter hose and use one from adapter to FPR and FPR to adapter. I want to use this braided fuel line from OUT adapter to IN FPR.

Thanks

The 90* fittings are push Lock fittings. The hose will be a little difficult to push on but once its on, its on unless you cut it off.

It does seem like he sent you more than you really need. The adapter will bolt to the rail, and 2 of the -6 an adapters will screw into it. mount the AFPR where you want it, add 2 -6 an adapters to the AFPR, run the braided line from the out on the adapter to the in on the regulator. Use the blue push-lock from the out of the regulator to the in of the adapter.

What you need is:

Aeromotive AFPR
Hahn adapter
4x -6an threaded adapters
2x -6an push lock hose ends
proper length push lock hose
-6an braided line

Maybe he sent you enough to use only the push-lock line, not using the braided line.

I could be totally wrong on this as Ive never played with an Eco fuel rail, but it should be the same no matter what vehicle.

Thanks DSM. I have the adapter with its fittings on and the 90 elbow hose fittings attached all pretty tight. I'm not sure if the braided line fits on the -6an adapters. Out of the other -6an fittings that have an o ring (meant for FPR I assume), 2 are bigger in size while the third is has a smaller end. This end fits on the braided line but not on the 90 elbows. The brass cap provided fits on this smaller -6an fitting. I was going to use this as an inlet and cap it as its not going to be used. Use the main 2 bigger -6an and put elbows on both, run hoses adapter elbows to fpr elbows (in and out on fpr).

The -6an(smaller) will be the feed from the adapter to the regulator and the larger -8an will go from the regulator back to the adapter. The return line is always larger than the feed to make sure that it can remove the excess pressure. If it were smaller than the feed, it would cause a resistance and increase the pressure.

The -6an smaller fitting screws in regulator but not on the 90 degree elbow hose fitting. Those fittings screw onto the larger -8an? fittings. The braided line also does not fit onto the adapter -6an threaded fittings, only the 90 degree elbow hose fittings.
