Need Fuel Line FACTS...

Kuips, thanks for posting those pics, it looks sick with the blue poly.

Thanks to everyone else who contributed. I think after all is said and done, I will be using the poly in the same manor as motorhead and kuips did.
 
I like the blue alot...nice job on the work.... :bump: ;)!

When I replace my lines I want clear or clear as possible to I can see where the gas is at. helps when starting them at the beginning of the year....

I did find some clear line before that still good as new that I ran on my jet skis. kinda like oem but can't remember where I got it...

Clear is just great... ;)!

Just so you guys know, that blue poly is okay but not as good as the stock lines. It too will harden and crack over time.

Personally I like fuel line from Motion Pro that is similar to what Yamaha uses stock. I would love to find a supplier of the exact same stuff Yamaha uses stock. This is about the best fuel line for a sled that I have found.

you are probably right, but the magazine reads as follows...

BLUE POLYURETHANE MATERIAL
-will not crack
-translucent
-won't harden from age
-not affected by sub-zero temps
 
Only OEM Yamaha line for this guy. As Ding said "it's the best". For under $50 you can replace every oil/fuel/vent/pulse (Yes these lines are made of different material depending on the job it does) line on almost any sled with OEM line.

I see guys use blue poly for all three jobs and and clamped with nyties????

And you thinks that's good???? Really????? You hold your sled together with nyties????

If you are buying line because of price or color you're buying it for the wrong reason. Buy line because it fits, because it's the right stuff for the job and because it will last WITHOUT ISSUES!!!!

I've been down this road MANY MANY MANY!!!! times with cheap line on sleds. ALWAYS ends up to be a problem, always. I wouldn't buy a sled with blue poly on it. I would be worried what else has been done to it that isn't right.

You guys buy/ride Yamaha because they are the best built, most reliable sleds out there and have been for most of their exsistance. There are reasons for this fact. The line they use is only one. Get a piece of new OEM line and compare it to new aftermarket. Give them some tests. Heat, cold, flex, kink, put it on the nipple and try to pull it off. Try routing that blue stuff in and around the things it should be going in and around.

OEM line will win every test you can think of giving it. Easily.

Get stranded out in the middle of nowhere once or burn up an engine because of a line problem and you will kick yourself. Hard!!

Yamaha doesn't put cheap line on their sleds. Cat and Polaris do. If you want cheap junk holding your sled together just buy a different breed of sled. It will already be on there.

OEM Yamaha line is the cheapest insurance you can buy.

Fuel line UPDATE--Read Possible fire hazard!!

Update. These lines didn't even last one ride. Started the sled today and fuel was pissing inbetween the carb nipple and hose with clamp. I found the hose was already swollen. 1/4 fits good on the fuel pump but alittle loose on the carb. 3/16 fits good on the carb but blows out on the pump. The line size HAS TO BE 7/32 for it to be trustworthy. Glad I wasn't out on the trail!!

I never had this problem 10 years ago when I worked on sleds. Must be this cheap CHINA MADE SHIT!?!? Sorry im alittle hot right now.
 
I'm glad you found out before you got stranded far from home. I have also found that oem is by far the best. It was always a challenge to find anything that would last on our old 440s and 540s. Every year when cleaning the carbs on the viper, I wonder how much longer the lines will be good. They are holding up suprisingly well. I don't want to badmouth others equipment but OPSLED is 100% right!
 
BTW, one time I "made do" with a piece of line to replace the pulse line on an SRV and it backfired and blew the line all to hell. Stranded-long cold walk home!

You know. ;)! ;)! ;)!

The rest can do as the please.

I look at other's sleds before I ride with them just to see if I think they may break down cuz I know I'll be the sombitch with the cold fingers when it happens if they are with me.

I'll bet your sled would pass the "ride with opsled" test.

So you are saying you like the oem lines??????...lol

LOL

fwiw, Polaris and doo use nice high quality fuel lines as well as Yamaha. Cat's I have not seen any issues on either. And if any will cheap out, it will be Arctic Cat.
 
I find the OEM fuel lines to be excellant, why would you think otherwise? Am I missing something here? I much prefer the Yamaha fuel line, to say cat or Doo's Polaris seems to last quite awhile too. Al

Just replaced all the lines on an '98 ZRT (rock hard, cracked them to get 'em off). Working on a '90 500 Indy with original lines that are still in good shape and are clampless. Hmmm.

I've used the blue polypro without issue on a lot of 4 wheelers, sleds, dirt bikes and PWC. Also, IMO - As long as the line size is correct and the nipple is barbed, using nyties in place of a worn constant tension clamp works fine. The clamp isn't there to seal, it's there to prevent blow off. Would I use them on a high pressure injected sled, no I'd use a crimp style Otiker with glass braided line. But with low pressure systems found on carbed vehicles nyties and polypro function well.

While I haven't had this issue with my Yamaha, I replaced the line on a '98 Big Bear last month and found the line glued to the carb and pet-cock. Maybe they use purple murple for assy but all the nipples had to be scotch padded to get the rubber off. Yup, it got blue polypro with nyties.

I'm the first to preach PM since I too have been the guy getting his hands dirty and cold fixing something trail side but in my experience nyties and properly sized blue polypro work fine. And for the record, the '90 Polaris pressureized lines lasted longer the '98 Yamaha Big Bear gravity line.
 
ive used the blue, clear and other lines, but i like how yamaha lines stay soft almost like silicone. they do not hold up to being rubbed through though :o|

Routing is the cure for rub troubles. Done right, shouldn't be an issue.

One really important point has been overlooked the brief couple times it has been mentioned.........

Yami bolts, Metric

Yami nuts, Metric

Yami bushings, Metric

Yamaha=Metric!!!

Cool Blue Metric fuel line would probably work better.......



just my $.02

just a oversight on my part, it snowed about 20" here and i wanted to ride so i rushed myself.
 
use what ever line you like just do not go smaller on supply lines! as for the use of zip ties use the ones for line there shaped different. personally i dont care for the oem hose clamps
 
The verdict is in: OEM all the way!!!

I installed the blue 1/4" line from Parts Unlimited, seemed ok, but was not impressed with fitment. Figured I take her out for a short run around the house to test it. Didn't even make it that far. I was tensioning the track and checking the suspension, lifting the sled up and down, working the suspension. Next morning I came out, gas everywhere, was leaking from one of the lines.

Good thing I had OEM lines on order for back up. I installed those and it was a night and day difference.

I am sold on the OEM lines and would never use anything else now. (sorry I doubted some of you)

I do realize I could have zip tied the Parts Unlimited line, but why go through the extra work, when you can buy the right shit first.

Lesson learned boys. (Just glad I wasen't 6 hours up in the U.P. just to find that out)

Have a good one, thanks TY Guys!
 
Where did you buy the lines. That stuff also swells up after a week of use. I fought with dennis kirk over the phone about it. The 5/16 was almost 3/8 after contact with gas. Such a waste. A few of the bends were starting to kink also due to the swelling.
