Topic: fuel line

What diameter is the fuel line used for the float bowl drains and where might I get some cheap?  It's for 750k.

Thanks!!

Try Ace Hardware. The clear vinyl tubing is cheap, and doubles as a float-level indicator, if you have carbs with drain-screws like K7-8 750s. I believe you need 1/4" ID tubing, but I'm not sure..

for 78 750k carbs

If they are hard, you can simmer them in wintergreen oil for about 20 minutes.  It might be cheaper.  Mine were very hard and splitting as I was putting them back on.  Afterward, they slid on very nice.

I actually did that to my carb boots with good results, but figured I'd just spring for new fuel line.  Couldn't be all that expensive, right?  Just don't know where to get it other than OEM.

I do not know what the drain line size is but that stock fuel line (5.5) can get expensive since they want to sell you something like 20-48 feet instead of what you need.  I have read that the clear line will yellow and that line may not hold up as long.  Since they sell in such bulk, wintergreen oil might be cheaper.

Just go to a decent hardware or autoparts store and buy what you need cheap. Fuel resistance should not be an issue since unless you have a leak not much fuel will ever go through them.

Went to Autozone, Ace Hardware and Home Depot and couldn't find anything I was happy with.  Autozone doesn't stock fuel line that small, but never thought to ask about other types of hose like windshield washer!! 

THANKS!

Agree with all the guys here. OEM is nuts to pay that price for drain hose. I took a float bowl off and went to my local hardware store to size it. Be sure you get enough for all 4...

  If there's a place near you that sells snowmobiles you can try them. That's where I've bought fuel line before. They sell it by the foot...1/4" i.d.

I got my fuel line here.....it's a shop that caters to race car builders, hotrods, aerospace, and the like down on Gasoline Alley near the Indy Speedway....

I never would have thought to go here to get anything, but another guy I know who rebuilds and restores 2 stroke dirt bikes gets his fuel line here and referred me there as well.  I don't recall the name of the line, but it is very rubbery (like silicone) and is bright yellow/green.  The stuff stays flexible and will not harden like the cheap clear stuff and won't dry out like the black rubber stuff.  I used the 1/4" for my main fuel lines and it works great.  Another buddy of mine also got the smaller size (1/8"??) for his overflow tubes and it worked great for that purpose.  I don't see the line listed on their website, but if you call them and just describe it, they'll know what you are talking about.  They sell it by the foot.

Good luck.

Why not, it looks correct and again how much gas will go through it more than once a year.

Well, since you ask.   
The vapor from the fuel will attack the rubber.  It's just not as fast to dissolve as with direct fuel content.  It will still break down/break off at the carb attach

The drain hoses are 3.5 mm I.D.  1/8" is pretty close.  Get some Tygon.  Hobby shops that deal with R/C air planes usually have that size and it is good for gas contact.   Don't get the type rated for glow fuel, as that is a different composition.

Um, Have you tried MC shops.  I think a lot of Japanese bikes used it.  Try some of the other dealers.

Cheers,

Tygon 2075 and 2375 are fuel resistant. The others will degrade.

Quit asking for fuel line.  When you ask for that any good clerk will bring you fuel line, and that is not what you want.  Fuel line is thick reinforced stuff made to take pressure and not burn through (very quickly) if exposed to flame or high heat.  All you are looking for is some flexible black tubing of quarter inch ID, any rubber hose will work just fine and 'windshield wiper hose' is near perfect for the job if you want it to look stock, other wise you can go to any pet store and buy some aquarium tubing (also sold at Lowe's and Home Depot).  If it discolors over time replace it, the stuff only costs about a dime a foot.
