using rubber fuel line with aeromotive FPR
 

I saw there was a previous thread about this, but I like the way the one in the picture is set up because of the 90* barbs. I'm having a hard time finding the adapter the barbs are threaded into. Anyone know where the guy got them?

this link is the closest thing I could find, but it says #6SAE not -6AN
.. is it the same difference?

#6 SAE/ORB x 3/8" NPTF Female (Steel)

could this be moved to the tech and performance section, it doesn't have to be 2nd gen specific i wasn't thinking...

That is an AN to NPT adapter. Summit Racing, Jeg's, Racer Parts Wholesale, and other similar online stores will carry it. Technically you are supposed to use an ORB fitting, so an AN isn't exactly correct.

Assuming your FPR ports are -6AN:

If you can't find an ORB to NPT adapter, then you may be better off using AN ORB fittings with AN barb fittings like this:

The standard AN fitting into the regulator wont work, there has to be an o ring seal without the tapered compression seal on the end. If not the fitting the screws too far into the regulator... Correct?

I haven't tried it, but that is probably correct. Even if the depth worked out OK, I would be concerned about not having the intended o-ring in place.

You pay out the ass for these, but here's the easiest solution.

You may have to grind down the flare on the -an side though.

Thanks for the help Evil Aviator.

If buying that adapter regardless of whether I grind the compression fittings down or not it looks like I'd need to get a set of fuel resistant o-rings. luckily I have some on the fittings that were in the used regulator, but I try to help others, I hate it when I find a helpful thread that only 90% delivers. For the people that see this thread and do not have the o rings laying around where is the cheapest source for them?

I'll probably go that route.. anyone know for shits and giggles if #6 SAE and -6AN are the same thread? It's been bugging me..

Besides cutting down the end, you would also need to turn the fitting on a metal lathe and under-cut a slot for the o-ring. I think you would be better off just continuing to try and find the correct ORB to NPT or ORB to barb fittings. Are you sure that the FPR in the picture actually worked without leaking?

Also, are you aware that the stock fuel rails will work with AN lines?

AN is a 37deg flare fitting. There are many different SAE specs. The 45deg SAE fittings are definitely not compatible.

well after doing some more searching if I'm understanding this correctly according to what I found these 2 links verify that -6AN 3/8 hole size uses a 9/16-18 SAE thread
http://www.gre6.com/ansize

and according to this. http://www.inserta.com/PDF/AI-STR-THD-PORT-DIM.pdf

SAE -6 (or "#6" according to suppliers web sight) thread is indeed 9/16-18

so IF those sources hold true, the original fitting I posted is the correct fitting, the fitting that would require no modifying.

ya I'm aware I could go that route if all else fails.

ill just have to order the fittings and find out through trial and error I suppose.

that thread size you found sounds right. I have a Parker hydraulic hose/fitting catalog and I believe that's it.

just a confirmation, i have received y fittings and yes the #6 SAE/ORB x 3/8" NPTF Female from the company in post #1 do fit wonderfully, so do the #8 and #10 model.

now all i need to do is buy the brass fittings. then the regulator portion is complete.

ps. just a heads up when ordering from that company you must purchas an order of 20 dollars before tax and shipping. i ended up having to pay 28.50 dollars after shipping.. but have enough for fittings for 3 regulators..

nice. just linked this information in a single turbo section thread: https://www.rx7club.com/2nd-generation-specific-1986-1992-17/using-rubber-fuel-line-aeromotive-fpr-904963/

old thread but i just was looking for the same thing and ordered it from grainger..

Also, you could walk into any local hydraulic store and walk out in 5 minutes with all the fittings you need. :)

For the record, you need -6 ORB to whatever-NPT adapters. Standard items at any hydraulic store.
