So I bought the Holley fuel regulator, however, I've been driving around Phoenix trying to the correct fitting (Checkers, Autozone, and NAPA), and no one has it! I need a 3/8" NPT to 1/4" hose fitting. Looking at a bunch of your guys' setup you are using these, but where the hell do you get them?

I bet that Napa is just out of them. But 1/4" hose? Is that for the return? You also have alot of speed shops there, don't you?

3/8 x 3/8 is what you're looking for. I know it seems odd but NPT regards the pipe inner diameter.

just went through the same deal last week. Advance auto sold me the regulator but didn't have any fittings that fit it. After some searching around, autozone ended up having some in the back and charged me only a dollar for each one. I guess I got lucky that day and came across somebody that actually took the time to search.

I tried the 3/8 to 3/8 but the hoses that are on the car now don't fit it, they're just barely too small. Maybe the previous owner replaced the hoses with something smaller? Has anyone else used a 3/8 hose connection (implying they have a 3/8 hose) on they're first gen RX7 for the fuel delivery?

im using -6AN (essentially 3/8")for my feed to the regulator and -4AN for fuel return.

for feeding the regulator you can use a strait 3/8" barbed fitting and connect it w/ 3/8" fuel line. as for a 3/8"npt -> 1/4" fitting , im not sure where to get'em, you might have to buy an adapter.

i wouldnt reccomend doing it, but if you gonna try to clamp a 3/8" hose to your 1/4" return, ide suggest that you put a fat bubble flare on the end of the hard line to lessen the likelyhood of a fuel leak

go to a hardware store and go into their brass fittings section. I found exactly what I needed there. 3/8" NPT x 5/16 hose barb. 5/16" fuel line fits best over the factory return. just be warned, it's a bitch to get the 5/16" hose barb into 5/16" fuel line.

go to your local parker store (they make hyd hoses) they should have any fitting you need to make it work
