I'm confused, why would you need to use this? I'm using -6an size lines and fittings with the Earls adapters for the fuel rails. Bottom of this page http://www.fc3spro.com/TECH/MODS/FUEL/fsystem.htm .

I'm confused as well. Both Russel and Earls make an assortment of metric adapters for -6 AN. You need M14 x 1.5 for two of the connections, M12 x 1.25 for another, and then you can tap the secondary rail for either M12 x 1.5 or (better) M12 x 1.25 (closer thread pitch, more bite in fewer threads). Then use standard fittings...

Ummmm...
I feel kinda dumb now...
.... dunno why he kept asking me about 6-an banjo fittings with the stock thread size..... Other than maybe its cheaper than buying the adapter and the hose end..

wow very cool! I've never seen that on fc3spro before! I'm going to do this with my rebuild. Anyone that has done this before, how much does this cost in total and did you replace the lines all the way back to the gas tank with stainless lines?

I have always used the the 12mm x 1.25 -6an that comes with the aluminum crush washer on the fpr side. (if memory serves me, it's been awhile) Should be a direct fit.
Its found here for 6.95

S4 has many benefits over S5. The threaded fuel rails is only one of many. 
Now, for S5 rails there are several choices:
1. Cut factory ends off, weld on new fittings. Can be tricky if you don't have a source of steel AN/flare fittings (hint: hydraulic store)
2. Cut off factory ends, braze on standard aluminium AN/flare fittings. Easily done with no special tools, and aluminium fittings are easy to find at any speed shop.
3. Retrofit S4 rails. There are some fitment issues as I think the primary fuel rail is taller and thus hits the manifold runners. Also the secondary fuel rail doesn't fit at all.
4. Make new fuel rails. It's not as difficult as it sounds. You can use a pice of square tubing, make injector bungs yourself (drill press and round bar) or purchase them, and then weld on the fitting of your choice (you can even get NPT bungs and then use the easy to find AN - NPT adapters).

I'll be attempting to convert my S5 secondary rail to steel weld bungs soon, hopefully this weekend. I'll post pictures and information afterwards.
I just ordered half of the parts yesterday, should arrive tomorrow.
