I use -6 an for all my fuel line needs

IP supply line woes

6 an and 6 jic are not the same, they do not mix and match. They use a different flare angle and the only way they will seal will be by mushrooming the sealing surface area which renders both fittings useless with their correct female/male ends.

From everything that I could find said they were the same except that AN is held to a tighter tolerance on the threads, they both use the same 37 degree flare.

Thank you Phillip, saves me from posting.
To the OP I have lots of those fittings in stock If you cant source them.
IP inlet is -5 ORB . That is what you need to tell the hydraulic shop or you may get a 1000 yard stare if you have an inexperienced counter person.
Filter head is 1/4 NPT .
I like the pushloc marine approved hose and related fittings.

interesting, so it’s actually the jic/an that share the 37* and sae is the one with a 40* flare, interesting to note that they specifically say that jic and am are built to different specifications of strength and that the difference are in the threads not the flare, except the jic fittings which use an o ring with the 37* flare, the an threads are 30-40% stronger than jic, but the angle of the flare is identical. Learn something new everyday, I still wouldn’t make it a habit to mix and match.

sae is 45, dont know where they got 40
A little explanation/history. Way back in the beginning of hydraulics, there was two common flare angles: 30 degree (Europe) and 45 degree (North America). The Joint Industrial Council decided to "split the difference" and make 37 degree flare the standard.
SAE remains a standard at 45 degree flare today, it is a lower pressure rating and it's used primarily in brass for airbrake where steel fittings cannot be used. 37 degree JIC is far more common in steel hydraulic fittings, and I would state that in North America, it is far and away the most common connection for hydraulic hoses and tubing.
Although there are two different flare angles, several manufacturers make a dual seated fitting where a 37 and a 45 degree angle are machined on the female sealing surface, making it so this female can be used on an SAE or JIC male spud. The exceptions to this "interchangeability" are sizes -6 (3/8") and -12 (3/4") sizes, where the threads on the connections are different.
AN fittings are interchangeable with JIC, but they are aluminum, and over the years have become more expensive than their steel industrial JIC counterparts. I would also say that JIC being steel and being generally rated to higher pressures are far more robust and harder to damage when over tightened versus AN.
JIC is a common and very available hydraulic connection, and you can flare tubing to mate to it pretty easily, so this is what I would always default to for low pressure connections (less than 500 psi) based on performance, ability to fabricate/flare on tubing, and availability.

Why wouldn’t he use a 3/8 fitting ? thats the fuel line size on my 94 IDI.
