Stock FC fuel line= -??? AN
OK I am going to buy a perma cool fan for my car, and I am going to buy the right fuel line for my car, since I am running fuel line that is not recomended for fuel injected cars. But I believe the stock size is 3/8 if it isn't that it is 5/16, but I can' remember, and I am going to buy braded fuel line, and the only size ratings the have is
-4 AN, -6 AN, -8 AN, and -10 AN, can anyone tell me which one of these fits the stock RX-7 fuel hose size, and what that sizing stands for??

You cant exactly run braided line without braided fittings. You should just buy standard 5/16 (factory) high pressure fuel line to replace. Unless you want to unload some serious money for fittings, just use black rubber line, and if you want something shiny, get a sleeving kit for it.

No the kind I found doesn't need fittings (or at least I don't think so) I am pretty sure that all you have to do is get radiator clamps.

it's -6 but you can't clamp braided line to a the regular hard line clamp end. you;ll need to get some steel -6 fittings, ( you can usually get test bench fittings for freefroma local hydraulic shop ), if not performance improvments is the only place out side of a few hydraulics shop that would have AN fittings in stock.
the typical fiting you'll get is a steel -6 to 3/8 NPT male/male fitting, cut off the NPT end, file the backside flat , counter sink the back side with a 3/8" or 1/16" larger drill, then simply braze the counter sunk end to the fuel line hard pont end, you'll need to do this 4 times for the return and the incomming lines, plus you'll need to get an AN filte as well.. I've done the same thing with both m PS pump and my oil cooler lines if you'' d like pics of what it looks like done let me know I'll send you some or post them..
