Does anyone know what the thread pitch/connectors the stock Fiero rubber fuel lines have on them? Working on a swap and for the life of me can't find how to connect to these stock lines

These are Parts of fittings that use Viton O-rings to seal.
Your "fixes" are...
1. Get other side on old engine & splice that hard line.
2. Remove the rubber side & use another fitting w/ hose barb.
If hose sections are iffy, Replace it. Needs same length and type.
To cut crimp bands use "dremel" w/ "heavy duty" cut wheels.------------------

That's what I was about to say. Nothing about those lines is "push on".
fliphone... take your hard lines that attach to the fuel rail to Home Depot, and check out their fittings. You should be able to find a match in the brass hardware section.[This message has been edited by Raydar (edited 09-04-2023).]

those won't match home depot stuff. they are "Sawginaw" aka "metric O-ring" fittings. I don't remember the sizes though. I used to have adapters to adapt them to -6 AN, if I can find them, I'll send them to you for whatever the ride costs. ------------------

Sort of that... Any standard plumbing parts won't fit not just parts from HD.
Many think they are some type of "flare" joint but the "Flare" is strain loaded only w/ the O-ring does all sealing.
The "nut" in top post has smooth bore in the middle just for the O-ring.
Is also used in other places like Fuel Filter for Fiero and some other models. TBI for Dukes have this too.
I don't know how GM size these... Don't count on Metric sizes either because vehicles made in late 70's and 80's often have a mix of SAE and Metric parts and tools needed to work on them. Example: Some S-column parts and mounting hardware is Metric but tool to pull tilt pins are SAE threaded.
I think the hard lines are 3/8" supply, 5/16" return and the hard line is Part of your fitting and use different size O-ring.

If you still have the hard lines that connect to those from the fuel rail you can cut them with a tubing cutter and use Dorman 800-135 to adapt them
to the nylon (plastic) lines if that's what you're using

Thanks for all the responses guys! I'm thinking what i might do is cut the rubber lines off, and flare out the hard lines to just run the rubber lines from there. I also thought it was a fitting i could probably swing through home depot and snag. ------------------
