converting inches to AN

I need to run some AN tubing/hose for my fuel system. My previous fittings are 3/8 and 5/16. Would it be -8 AN that would fit these?

 

AN = size in 1/16"

1/4 = -4
5/16 = -5
3/8 = -6
1/2 = -8

etc

 

1AN = 1/16 of an inch.

As in - 8an= 8/16, or 1/2.

 

OK, thanks guys. 8 was suggested to me, glad I didnt order before checking on how to convert! looks like 6 is my ticket.

 

the dash number is the size in sixteenths= dash 6 is 6 sixteenths or according to jr high math=3/8's.5/16 would be -5 which is not very common,but can be found.dash 8=8/16's[1/2 inch] and so on

 

-6 is 3/8, -8 is 1/2 and i think -4 is 1/4 and 5/16

 

man I'd be dead last in the typing drags

 

-4 is 1/4"...-5 5/16"...-6 3/8'...-8 is 1/2".

Be advised, "AN" flare is 37-degrees....SAE is 45-degree. You cannot inter mix these seat angles.

Most all AN hot rod stuff is aluminum. SAE is steel & brass @ 45-degrees. Now to really confuse you; "JIC" is also 37-degree, mostly in hydraulics ( industrial ) and fittings are steel.

If you're plumbing w/ braided stainless..use the Earls or whatever. However, in hidden
places you can use Stratoflex, Parker, or Gates or other truck shop style re-useable fittings & hose at a reduced cost. IE; hidden oil pressure lines, fuel lines,etc. The low-pressure fabric-wrapped, 2-wire hose is cheap.

Don't overtighten aluminum AN...or they will "gall" upon taking back apart.

Good luck

 

Going to do the "push loc" stuff whith a nylon hose. Not going far, from the factory location fuel tank to the back of my motor in my 61 f100, but need to run stuff that can handle pressure.

Thanks for the tip on the degree of the flare, that could have made a mess

 

Make sure you use hose that is designed for Push-Lok fittings. Regular fuel line won't cut it! Earl's Super Stock hose will work with push-lok ends. I try to stay with Parker hose when possible. I figure if they invented the stuff, it ought to be pretty good... Parker also offers a lot of colors of hose, so you can "code" the plumbing by what fluid is running through it.

 

Be aware that pushlock style stuff uses rubber hose & today's fuel will eat it up pretty quickly. Most SS hose on the market is made in China & you know what quality that shit is.

I suggest you look at using teflon lined hose for safety, because the alcohol in gas won't eat it up. I used this hose source: http://www.techafx.com/

Here's a good article on hoses & todays gas:

Sorry to disagree, but I've used Parker Push-lok for the fuel system on my Methanol fueled supermodifieds for over a decade. The hoses hold up just fine on straight Methanol, so I wouldn't see E15 gas being an issue...
