FUEL TANK LEAKING PETROL....

From what I understand is the ethanol evaporates rather quickly and builds pressure in the tank causing it to warp. I also use Star Tron OR Stabil marine grade. They don't rid the gas of ethanol but help in combatting its effects. I may not always use the stuff because I'm refueling every week, so there is not enough time for the ethanol to evaporate. Winter storage though is imperative. Some folks just open the fuel cap to alleviate any pressure that might build up. Use the bike often enough to not have to worry so much. 8)

Surely the tank breather would allow any such pressure to escape...?

One would think. I've heard of this happening to the Ducati's long before I purchased my Norton. I've also heard the problem was addressed and corrected with the Ducs as well as being told same with Norton before I purchased my 2013. I haven't had the problem nor have most owners so I can't really have an opinion to share.

Sure would, I also work in the industry as some may know, and have not heard of a tank in the UK in recent years being affected....

What would constitute an affected tank? There are some reports on this forum that appear to fit the bill. When I was at the factory recently I saw two bikes where the tanks had expanded and the plastic was butting up against the oil filler neck. Normally there is a reasonable gap there. These were pointed out to me as expanded tanks (ie not just badly positioned).

It feels like the "industry" is in denial, something I have experienced with a number of different manufacturer issues over the years.
 
FUEL TANK LEAKING PETROL....
.

Anyone had any dealings with this alleged solution? , seems like some special magic sacrificial little lump of tin/galvanic type metal ???

The fuel diamond is very simple to use, simply drop the fuel diamond into your petrol tank via the filler pipe. The fuel diamond reduces the risk of the petrol in your fuel tank going stale over winter lay offs infact if you have a car or motor cycle that you do not often refuel due to little use the fuel diamond would be ideal for you to use.

  • It stops the what can be a rapid drop in octane
  • It stops the change in fuel colour
  • It stops emulsification
If fuel becomes stale in your tank it can make starting difficult it can block fuel lines carb jets fuel pumps etc. Now there is no need to drain your fuel tank during lay offs which can allow moisture to enter the tank and fuel system.

The fuel diamond is guaranteed for 5 years it will treat a fuel tank of up to 60 litres refill after refill after refill. If your fuel tank is larger than 60 litres simply put more than one fuel diamond in your fuel tank.

Richard , My advice is that you treat every gallon of fuel you put in the 961 . If you are traveling , then of course wait until you get back home ! How do you get the fuel diamond out of the tank when used up ? Take off the tank and shake it out ? I would be afraid of it getting caught in the fuel pump .

Well Tony as u know I’ve done around 19,000 miles & at say a Conservative 40 mpg , (know I’ve had 50mpg often ) that’s 475 gallons have gone thru that little tank , countless spils on paintwork & the tank touch wood is still in one piece with no paint peels or loss of shape , never put an additive in,always gone for dearest fuel at every gas stop , think 2016 was a good year for 961,s

Would a large lump of lead solder have the same effect?
 
All they have to do is submit their product to a reputable testing lab for testing and final proof.
If it works as stated, the owner will be the next internet billionaire.

Roger that . It is more corrosion prevention with the internals of the fuel system that worry me. If the bike is driven continuously and fresh fuel put in frequently , then everything will be just fine.
 
I use Statron and/or Stabil blue marine grade. Then again, with pop up joce weather, a tank never lasts me more than a few weeks.
Anyway, heard through the grapevine fron a few boating buddies that Startron has been known to gel and screwed with a few fuel systems. Haven't researched and confirmed yet. I'll get back on that one.
 
I was able to isolate my leak to the fuel cap overflow line where it travels through the tank. Looks like Norton used a threaded brass collar to pass through the tank. Repaired it on the inside of the tank with plastic fuel tank repair kit back in Septemder. Still no leak. I thought it was the fuel pump "O" ring but it continued to leak after I replaced it. Continued to investigate and found the the fuel was leaking from where the overflow line exits the tank under the tank. It was just running to the lowest point which was the area of the pump.

Good troubleshooting ! Are you on the list for a Alum tank if that ever comes to pass ?
