Updated April 4th 2014:

It seems another large number of fuel leaks have occurred since the last update in September 2012. I expect we should be wondering why Yamaha has not done a recall to cover the 2002 left side dry-break, and also the fuel tank outlet Filter Assembly for the slipping-nipple that could spell disaster for any of us. I'm not wanting to be a 'mixer' I only want to document what's happening so we can continue to point Yamaha and it's dealers here when appropriate and when beneficial to safety.

Many members continue to point members here to this thread when we see they've posted about a fuel leak hoping that eventually there will be adequate data for Yamaha to perk-up and pay attention. We might be getting there. So if you have NOT yet reported a fuel leak on your Warrior here in this thread, please chime-in with the details and particulars, and especially please include your bike's model year. Its important we avoid duplicate reports so please check all the posts to be sure you have not reported prior. Then see Post#2 (below) for the places Warrior owners have reported fuel leaks.

This update includes Item# and Part# so we can visualize and locate the subject part much easier using either the Parts Manuals or using the Star Motorcycles disassembled views available on Yamaha/Star MC's website and also on many Yamaha/Star Dealer websites. All these parts are in the 'Fuel Tank' disassembled view.

Leak in Main Fuel Tank elsewhere: 1

--------------------------------------------------------------

Additionally, a forum search yields fuel leaks due to cracked fuel pump 'nipples' over the years, regardless of model year.
Its a great idea to keep the area around the fuel pump nipples clear, same as stock, to avoid this trouble.
Note the 'links' at the bottom of the Original Post (above).

Leak in under-seat dry break (maintenance/operator error): 7
Leak in under-seat auxiliary fuel tank itself: 0
Leak in a fuel hose 'clamp' (maintenance issue): 1

2003 Warrior.

Rear tank bracket fractured on the spot welds, had it welded, all ok.

About a year later, suffered a stress fracture in the skin of the tank on the underside (right side, from above the tank). Welded that it, but it fractured further along a few months later. Bit the bullet and bought a new tank.

All info on problems in my posts.

02, bottom plate near seat. About where it would leak where they did the recall and replaced the pad. Took it to yamaha couple years ago. They said the recall was done on my bike and they were not responsible. They said probably corrosion, I say bs. corrosion maybe, but caused by vibration of the undersized pad.

My response was that the damage was already done, it just took a few years to fail. They still said no. Ended up buying used black cherry tins here an changed from imperial red. like the new color but still feel jilted. Still have the original leaking tank.

Mine was operator error. One of my fuel lines behind the left side cover didn't get tightened on enough, and would spray.
I feel pretty lucky after seeing recent posts that I didn't catch fire, because I didn't notice mine right away. It wasn't until I was done riding and saw fuel dripping down the side of the bike. God must have been watching over me there.

02 w/12k miles leaks at the underside rear bracket and at the seams around the edge in multiple locations both front and rear. Fixed it with KREEM tank liner - no welding.

It seems mine has developed a leak around the fuel filter. Its a slow leak, maybe a drip per minute. I noticed the puddle in the garage this morning after having the tank off yesterday. I took the tank off and took the filter off and then put it back on tight. It didn't look bad, but I think that's where its leaking from. Just enough to ruin todays ride while I figure out what I'm going to do about it...
