What Tank is that?

[Darkness]

I'd like a little advice: I'm thinking of selling a spare fuel tank. It is a steel tank and came fitted to a carby M900, but it certainly isn't from '93.
Can anyone tell me what distinguishing features I need to check to work out what it was intended to fit?

Well, as you know, the font changed to the type on that tank when TPG took over from Cagiva as Cagiva own the copyright to the previous font (hence why no current official Ducati merchandise uses it) so if the paint is original then it dates it to post the takeover but (as its for a carb’d bike) pre fuel injection.

Have you looked underneath? As often there is some kind of month/year marking.

[Jez900ie]

I can't tell you what year yours is but the Ducati decal on the tank is the same as a 2002 900ie.

Here's a pic of the underside of a 2002 900ie tank; if yours is the same then you will know the answer to your question!



The green line I have marked is so that you can reference the distance as a secondary point of comparison; if yours is an '02, the green line will be 230mm +/-

I am very interested in this thread as I have a tank I was sold as a 900ie, which does not fit! I'd like to be certain what it does fit before I put it up for sale, as I would not want anyone to be shafted the way I was...

Neither is the lefthand switchgear.

If it has the front seam near the clip its pre 97. My tank now is off a 94 m600.

[Darkness]

It looks like original paint, and there's no seam at the front around the tank catch.

And I now know it isn't for a 2002 900ie [Thanks Jez]' I didn't measure the width, but the step in the base is much further forwards::



It looks like an injection tank with 'Delivery', 'Backflow', 'Bleed' and 'Drain' connections underneath:



I haven't taken the filler out, but the pump gubbins must be pretty well hidden [Or absent]?

[Darkness]

Has no one noticed the wheelie bin in photo' 1?

[Mr Gazza]

It's difficult to see from the photo, but it does appear to have the early tank seam?
However it has the filler cap with the larger bezel which I think is unique to the steel tanked injection models... Larger to allow the fuel pump to pass through.
The plastic tanked injection models had the pump installed from below and so had a smaller filler, as I think, do the carb models?

The decal is the later font, but it looks wrong to me. out of level and too low?

The fuel level sender plug will have two cables for a carb model and four for injection.
You may be able to get an endoscope in there and see if there are "C" clips for a pump and filter, otherwise it's the tedium of removing the filler cap to see.

The radius where the front of the seat fits could say if it's early or late. About a 10p radius for early and £2 coin for a later one.

You might possibly find some numbers stamped in the side area covered by the seat.
I think my 2000 tank has 00 stamped there both sides.. it's hard to see under the thick paint!

[Darkness]

It doesn't have the seam Gazza, and it's my photo' that's out of level.
The underside is different from an eBuy S4 2001 one:

That looks more like your M900ie one Jez.

Lots of bikes it isn't, not yet sure what it is for though?

Its a bloody nuisance! The one I have that I'd like to sell, is exactly the same as that one in your pic. I really want to know what bike its from though can you confirm it works perfectly on a M900 carby?

[Darkness]

It works fine, though I don’t know what’s been done with the plumbing inside?

[Mr Gazza]

Okay it's definitely an injection tank, but the cut out for the aircleaner box and battery is much smaller than on a 900 or S4. That could mean that it is from a 620ie, but not sure if they had steel or plastic tanks?

look on the grey Ebay tank, zoom in on the seat cut out on the first picture and you will see two digits stamped. There is a definite 1 and another vague figure.
What does your tank have in that area?

Pretty sure it was only the 620 'Dark' models that had plastic tanks- I know JMo's 620 definitely had a metal tank.

Some 620 plastic seem to be red too, but you can’t always believe what the vendor says it’s off. Ricky seems to be having a similar problem.

Its only a partial bin so hardly worth mentioning

[Darkness]

Looking at the parts books, I notice that the 2001 M900ie still had the vertical mounted battery [As well as injection], whereas the 2002 M900ie introduced the horizontally mounted battery that necessitated the larger tank cut out.
Could that mean my tank is from a 2001 M900ie? Can anyone here confirm [Or deny] my suspicion?
Thanks.
