Default Stock 7/9 fuel lines to AN underhood

Honest I searched... And could not find a definitive answer except for fuel rails.

Has anyone used an adapter fitting from the drivers side under hood hard fuel line to AN?

It looks like the fitting is a M12x1.25 bubble flare compression, like a brake line..?

The closest I could get to an adapter is this GM TBI fitting: https://www.jegs.com/i/Russell/799/640800/10002/-1
Russell part number 640800

I would assume all 7/9 and even 240s may have the same under hood fuel line connection and that there would be an adapter available???

Any insights are appreciated.


Thanks!

I'm pretty sure that's a ½"-20 SAE (45°) flare fitting. I don't think there's an adapter made to go directly to AN.

How much of the fuel system are you replacing?
Are you fixing a leaky junction?

Let me check the threads for 1/2"-20 tonight. I figured metric and it did line up with 1.25 pitch like a glove.

This is for using the stock supply line for a LS swap. On the LS side I can easily get to -6AN, but looks harder on the Volvo side than I ever imagined.

At worst I can tube cut the flare off and then place a compression fitting on there to get to AN. But I would rather not cut it up if I don't have to.

Huge Thanks! I thought this would be easy, but no.

The fuel rail inlet tube will survive cutting. The compression fitting size that fits the tube is 5/16 inch. I cut off the fitting and installed a tee fitting and a Schrader valve. Installed the end fitting back into the inlet of the tee fitting using compression fitting hardware.
