Topic: Replacing fuel lines

[RainCityRider]

Hey, What is the right size and best fuel line to use on my 78 CB750K's? Mine is gooey and crumbling. Do I need to get one that will work with ethanol gas? The Gates stuff looks good.

2 years ago I got Honda gas lines from the dealer.  He cut me off all that I needed.  Fits just like the original and so far todays fuel has not caused any problems.

I buy yellow Tygon lines on hebay, dont remember the size now.

I get clear ethanol-safe stuff meant for snowmobiles. 3/16" size.

[rocs]

I go to sears hardware and buy whatever length I need for like 33 cents a foot.

5.5mm is the proper size. 3/16 wilil cram on but is too small. 1/4 fits but you'll need a clamp.

The dealer OEM stuff s/b 5.5mm, but sometimes they shortcut it with an american size above.

IF you use American it should be 7/32"

Seems that online snowmobile places have the proper size 5.5 with different colors. Dealer OEM is all solid black.

Motion Pro from the MC store (1/4" + clamp)

 I've had 1/4" leak even with a clamp. Not worth it IMHO.

Dealers should have the right stuff or it's on ebay. Don't use vinyl or silicon, they degrade rapidly in gasoline. Tygon makes a lot of tubing types, only a few are good with gasoline and some of those are not very flexible: make sure you get fuel safe type and that it's flexy enough for you - hard to do when buying online! They don't seem to have any 7/32 - 5.5mm fuel tubing though.
I would stick to the OEM black tubing.

Like Steve and Bodi said, save yourself a bunch of trouble and get the real fuel line from the Honda dealership. They will bring out a big spool and cut off whatever you need. I think it was $1.72 a foot. You'll only need a few feet and you won't need to worry about it again for years.

Agreed. My problem with that is the last time I bot fuel line from a dealer they cheaped out and only stocked the 1/4", rather than popping for a roll of the good stuff.

MAny threads here on this. We bot some minimum orders (25Ft I thnk) from a snowmobile place then sent it to forum members in shorter lengths. Marked up a tad to cover the freight. Win win. Had colors too, gold and clear, in 7/32.

I have been using Tygon for years. Easy to route without kinking and is self clamping. I buy it from a small engine shop since leaf blowers and other small motors use it a standard. The roll they cut it from should say "Fuel Line". I have a K8 also and getting a clamp on the fuel inlet is a #$%*. With the Tygon you spit on it, slide it on the inlet, on the petcock side and you are done.

What honda dealers do you get the fuel line from? No one near me carries 5.5mm. I need more too!

Glad to see it's not just me getting stung by the dealers.

This is the place from which we did 2 group buys:
https://www.alssnowmobile.com/PRODUCTPARTS.ASPX?pn_deptid=304
Scroll down to 5.5 / 7/32 fuel line.

Somebody (me and someone else) bought a $25 worth plus the mandatory $15 S&H. Then sold it off to forum members for cost plus. Only a few stamps to mail a few feet here and there.

Very little else makes you feel like you've done the job right than 5.5 mm fuel line. I prefer clear cuz I like to see what's going on.  Black is better for orig repros, granted.

The clear or yellow? Looking for the regular black stuff

The someone else was me.  I bought bunch of yellow and blue and sold to forum members

Yeah goldarrow.

Tews: we were dealing in clear and tinted. I have some black I think I got from Yamiya years ago. But I don't see them listiing any right now. I don't think i have any to spare. I'll check late tonight.

There is some black on ebay right now, pushing $4ft for short sections. Stings at first, but you'd love it.

[goldarrow]

I could probably try to run the fuel line operation again if enough members are would want them.  I know member Hush asked couple of months back.  Need to do math again to see if selling price would justify the cost

just to confirm, the 5.5mm is the ID, correct?

[MCRider]

Keerect. I noticed in my browsing there is a size for R/C hobbyists that is 5.5OD and something smaller ID.

Ours is 5.5mm ID.
