The inside diameter is very close to 1/4" on my '81 XS so I used 1/4" fuel line. The only problem is that the original hose clamps(Springs) would not fit the increased outside diameter. I found new hose clamps(marked Fuel Injection Hose Clamps) at Pep Boys. They are the perfect size and are very secure. I didn't like the thought of a fuel line coming loose on the interstate and gas running over me and my engine.

I tried 8mm on mine, but it came on a bit too easy, so I bought a 7mm hose... a bit too hard to get it on... well... didn't try it yet to tell the truth. But it sure as hell won't come off

Officially it is 6.5mm id. But at 25.4mm per inch it comes out to 1/4"

As a note about tubing. Motion Pro sells Vinyl tubing but I have been using polyurethane ether based black tubing with EXCELLENT results for low flexibility apps.

I too am looking for the perfect hose. Will let you all know when I find it.

I prefer not to use clamps. It makes things a lot easier when you have to remove the tank. They never leak -- knock on wood!

1/4 inch, no clamps, no leaks (yet), lines haven't come off (yet)

I have used all the different type material, of fuel line(s) , that are shown in the "DennisKirk. " catalog, and shown in
the "Chaparral" catalog. Except the Gray Tygon; ($66 for 25 feet of the 1/4 inch).
I buy 'em in rolls, when they come that
way; and I buy all the different sizes from 1/8" thru 5/16" .
I , long ago, stopped using the "black rubber type", CUZ I want
to be able to see thru my fuel lines. I feel secure , to be able to
look at "the octopus", and today see if there are any polywogs
swimming around, air bubbles, water bubbles, or fuel. All my lines have see thru glass filters (4), and inline fuel shutoffs, just
in case my petcock gasket/seals have decided to take the day off.
I've used the nylon reinforced (it'll harden within a week);
The clear vinyl is about as bad. And you gotta use clamps to keep
'em from leaking. You gotta use clamps on the "black rubber", or
anything that the heat or fuel makes to get hard. The vibration
will get to 'em, eventually. Unless the line, inside diameter, wuz really too small, when you crammed it on, when it was fresh.
My favorite, is the Blue polyurethane. You don't gotta use clamps, when you feel it go on snug. Easy to work with, cuts real clean, with a jimdandy pair of snippers. When it's 2weeks old, or a year old; and you pull it apart, it's still the same to work with. Instead of the lines that would turn hard. You can stick it back together; no clamp necessary, unless you reuse it on a different smaller size item. Also, you can make a tight bend with the "BlueLine", and it won't kink.
BTW; the real octopus , that has been made without being miserly with fuel line, should be held in place (not snug) with the"plastic 'handcuff type' ties". Kind of , like, "guided" .
Couldn't have done it , my way, tho, with the standard airbox.
My jimdandy vacuum piston diaphragm, is clamped to the frame in front of the battery.
A marvel to eyeball.

Yeah Tygon is the way to go for sure. It seems friendly in every way.

......well, I think I'm also addicted to the color of the
BluePolyurethane; a few days after the fuel and heat have been
exposed to the new line(s), they turn a neat jade green turquoise color. AND , I'm really spoiled , to be able to see thru
those lines.

?????? Can you see thru the Tygon?

There is a seller on Ebay with a good assortment of fuel line, colored, but is still see trough.

One of the auctions IS HERE!

I go with the 1/4" yellow Tygon, too. Yes, you can see through it, and it doesn't harden. I always use clamps, though. Just in case. I think you can see the lines in my avatar, if you look close. I like the color contrast.
