HSR Fuel Rails

I bought a HSR setup off the forums here and my fuel rail just has a large threaded hole on the back of it. Does anybody know what size it is so i can order an adapter to make it -6 an? Also what size is the fitting going into the fpr?

Here is the stuff im ordering so far.
EAR-306006ERL 6ft -6 an earls autoflex hose "is this enough or 10ft"
991954ERL Earls Performance 14mm to -6an adapter
991955ERL Earls Performance 16mm to -6an adapter
RUS-624260 Two Russel 120 degree -6 an hose ends
SUM-800260 Fuel Gauge
HLY-26-69 1/8 in. NPT Male, 1/8 in. NPT Female 90 degree fuel gauge fitting

Re: HSR Fuel Rails

Just looked up the Holley 534-185 fuel rail instruction manual. It doesn't say what size they are. All it says is the parts are called an inlet fitting and a regulator return fitting.

Any help would be appreciated.

Re: HSR Fuel Rails

I need to know this info, as well. It's probably on this forum somewhere. Just gotta search for it.

Re: HSR Fuel Rails

I just got an email from holley. The factory part numbers are 9906-127 for regulator and 9906-122 for fuel rail. Since 89fbirdformula's parts seem to be 1/2 the price I think ill be going with them. Thank you 89birdformula.

Re: HSR Fuel Rails

I ordered this for the rail and it works great
http://www.summitracing.com/parts/EAR-985006ERL/

I ordered this for the Regulator and it doesn't want to thread in
http://www.summitracing.com/parts/FRA-499206/

It looks like the threads on the adapter are too fine to fit into the reg. I didn't try to force it because I didnt want to cross thread but I tried for quite awhile. It looks to be the right size but just wont thread. Any ideas? Did I order the wrong part?

PS. I just tried the rail fitting in the reg and it wont thread in either.
