Fuel line for Dax kit

    I either didn't get a fuel line with my kit - or I misplaced it somewhere. Either way, I have to get a new one.

    Can anyone tell me what size the fuel line is? Also, is it just the surgical tubing, or does it need to be specific fuel line? Perhaps Home Depot has some replacement line for a lawn mower?

    Any ideas would be appreciated - Thanks!

    Here's what I'd do, depending on how quickly you want to get going. First of all, you really want a fuel filter. So if you don't have one, order the filter + tubing from thatsdax.com.

    Now, if you have a filter, and want to get going /now/, then order the tube from thatsdax.com, and go out and buy surgical tubing. Use the surgical tubing temporarily.

    good luck

    The fuel line from Dax is certainly offered cheap - but I would like to start the bike tomorrow if possible.

    Anyone know the size of the fuel line?

    you have a petcock (valve) & a carburetor, right? is there any chance you could simply go match some up and let us know what you used?

    You can get fuel line and filter at Home Despot.

    Don't buy the clear yellow tubing from home depot...its just a tiny bit too big for the carb and filter but not on the petcock

    The yellow tubing from Home Despot works fine on all of my bikes. I do use a small zip tie on the carb to cinch it a bit so it doesn't leak.
     
  8. Your local auto parts store (Auto Zone, Pep Boys, Advance Auto, Murrays, Fisher Auto, Etc...) should be able to help you...Just bring the carb or tank so they get the proper size line for you.

    Good luck...Oh....as others have said to try to use a fuel filter too.

    Hey all -

    I don't mean to "threadc**p" on the original poster, but this seems like a relevant location to ask a question of mine. Also, I keep seeing reply posts to people who started new threads for already-addressed topics, asking them to post on an already-existing thread. So here goes.

    I am the proud owner of a Dax 70cc kit. My Schwinn Skyliner is on order from Walmart.com. I figured I'd get a few essentials in the meantime, before the bike comes in. I needed a fuel filter, fuel line, 2-stroke oil, and a chain-breaker.

    FUEL LINE:
    I went to Home Depot and picked up some Watts-brand 3/8" x 1/4" clear vinyl tubing. It's much sturdier than the latex tubing they had, and I think that, when used in combination with zip ties, it will provide a good, solid fuel line. Any word on gasoline reacting with vinyl, though??

    FUEL FILTER:
    First I looked at thatsdax.com for the fuel filter, but they are currently (as of Nov. 6, 2007) sold out. I couldn't find any fuel filters at Home Depot, so I ended up heading to Autozone. All they could offer me were two different types of in-line fuel filters. I could really use some input here. Because they were cheap, I decided to buy both kinds. They're made by Maxpower, and are product #4286 ("for engines without fuel pumps, for 1/4" fuel line, replaces Briggs & Stratton #298090) and #4283 ("for all air cooled engines"). Any comments on whether these will do the trick? I also went to Walmart and found a fuel filter that looks very similar (maybe a bit larger?) to the Dax-recommended fuel filter. It is a Fram-brand G2 fuel filter. Also cheap, so I bought one. Any suggestions on which, if any, I should use?

    OIL:
    Autozone only had marine-grade 2-cycle oil. I assume that marine-grade is still compatible with our bike engines? Anyway, I ended up with the Pennzoil Marine Premium Plus 2-cycle synthetic blend outboard engine oil. TC-W3. Has anyone else used a similar "marine" oil, and do you think that it will be ok?

    MISC.:
    Walmart also had a Bell ChainMender and FloTool measuring/mixing oil funnel that will probably come in handy.

    Thanks a ton for reading this far, and for your help!

    do not use marine grade 2 stroke oil. this oil is designed for marine outboards that are cooled with a water flow and breaks down at much lower temps.
    I personally use bel-ray h1r 2 stroke oil. It is synthetic and very good...also makes less smoke. You can get it at any place that sells motorcycles, except perhaps a harley davidson dealership. As for the fuel filters... try them out and see.

    Thanks for the comments!
     
  12. If you are close to an auto parts store you could ride down there (pedal!? AARG HA)
    and get everything you need with one stop....fuel line (make sure it is fuel line not just rubber hose), filters, clamps etc...probably the smallest automotive line would work.

    likearock111,

    Either of those filters will be fine. I use the red one on my bike with no problems.

    The vinyl fuel line is ok but it will eventually get stiff and brittle with exposure to sun and fuel. It will probably last at least a year though. I like the latex surgical tubing the best for short runs like we use on these bikes. It stays nice and flexible and, if properly sized, stays put without the use of clamps.

    I would advise against using zip ties as fuel line clamps. The area where the tail goes through the ratchet does not apply pressure to the fuel line and can therefore actually cause leaks where none would have existed without a clamp. You're better off with a full circle type clamp. The type that you squeeze with pliers are good. The lawn and garden (lawn power tool) section of the hardware store or home improvement store usually has them. Worm drive type hose clamps are no good either for the very small fuel lines.

    Good luck and have fun!

    Yeah - that's what I thought, too, but AutoZone didn't seem to have much selection at all as far as two-stroke oils or air filters. Maybe a trip to Napa is in order. Thank you!

    Good job on posting in an existing thread, it's much appreciated. You sound like me in the sense that these filters seem too cheap to be any good (I think) but you're just trying to keep any little trash out and the paper filter should do a fine job. I have a 2cycle Lawnboy Lawn mower so I used the Lawnboy 2cycle ashless all season with preserative and broke my bike in on that. I worked that lawnmower hard in hot dusty rough Texas summers so I trust that oil. I think the rule of thumb is no synthetic untill it's broken in, but I'd look into that to be 100% sure since I'm not.
    Good luck.

    I use the 5/16ths neoprene clear line (the same used in racing carts). I have used zip ties but you have to tighten them to the point where the soft line gives in all the way around the fitting. Works great but why not buy a 1/2" hose clamp. Well now that I think about it, the hose clamp has the same flat spot on it as does the zip tie. Maybe because you can get more pressure from a worm gear than a zip tie.
    I got 5 gas inline filters for 7.00 on Ebay and you will probably want a lawn line shut off valve, also cheap on e-bay.
    If any of this helps, GREAT.

    Today I asked the AutoZone people for fuel line, and they came out with this really beefy, thick black stuff, so I'm thinking I'll go for that. Also, they had some clamps specially made for the fuel line, so I bought some. Many thanks for all of the helpful responses!

    Can't wait go get STARTED!

    I spent a fair amount of time looking for the right sized fuel hose after the one that came with my bike hardened and started to leak. And what I found was that the inside diameter is indeed 3/16". I went to Walmart, Home Depot Kragen, Ace Hardware and probably a few other stores. The best advice that I found in this thread was where someone said to take either the fuel tank or the carburetor to an auto parts store and see what is the best fit. Not wanting to take my gas tank or carburetor off I just unscrewed the gas supply nipple (for lack of a better term) and took that with me. I measured it and found it to be 3/16" as I said above. One thing to be careful of is that the reinforced fuel hose (black usually) has thick walls and may be difficult to install on the nipple when the nipple is attached to the carburetor. Anyway, I did find what I needed at Kragen Auto. Ace had a sample piece on a price/spec board but didn't have any in stock. And they didn't have the right size in the non-reinforced hose. I installed my new hose when I got home and it was nice and snug with no leaks. Finally!
