Hello,
1992 Ford Ranger Supercab with 2.9 V6.

Does anyone know what inner/outer diameter and AN size fuel line for my truck?
I'm troubleshooting something. It's very old fuel line.
Looks like there might be newfangled connectors on the market compared to the OEM ones I have. Any recommendations ?

IDK exact diameter, but it's 5/16 and 3/8 nylon. Whatever those measure out to. I think those are the inside diameter.

Factory nylon lines were 5/16 which doesn’t really equate to AN. Technically it would be a -5AN which doesn’t really exist.

On my 89 Choptop Bronco II the fuel lines got replaced with -6AN braided PTFE for the pressure and I used it on the ends of a long run of 3/8” aluminum line for the return. Think the EVAP line ended up being 1/4” Ni-Copp because that’s what I had the right size.

On my 00 green Ranger I did -6AN braided PTFE for everything except the EVAP. My only complaint was dummy me trying to do it piecemeal instead of all in one go. Blew the old line remnants about a half a dozen times before I just tore it apart and did the rest of it.
