Carbon fibre fuel overflow tank for 998 - does it exist?

Great Ducati gurus, I call upon Thee!

Some time ago I saw a very neat fuel overflow tank made of carbon fibre for a 748RS.

I'm not sure it's actually called a fuel overflow tank but I guess you all know what I mean.

It was mounted underneath the main fuel tank and there was a fuel line running between the two tanks allowing the smaller tank to catch fuel spills from the main tank.

Do any of you know if such an overflow tank would fit a 998? And if so, do you know where to get one? And perhaps a price guesstimate on top of that?

Thanks!

Respectfully yours,

Polar

The one on the 748RS is a coolant overflow tank.

I doubt the 748RS one will fit the 998 because of the injection/airbox difference.

I just took a look at the 998RS fich and it does not have a similar tank.

Thanks for helping me out, Jason (as always)

I really thought that was a fuel spill reservoir. Strange, really. I even believe the owner said that little tank worked like some sort of an expansion chamber connected to the main fuel tank but it it doesn't matter as long as it doesn't fit on a 998.

So the question remains... what do I use? Any suggestions out there?

For a coolant overflow? Where is the stock one? Is it missing?

LOL

The fact that you constantly keep referring to the coolant system makes me realize I must have gotten it all mixed up, Jason.

As far as I understand it's got nothing to do with the coolant system. I'm on thin ice now but I believe the 748RS had a little carbon fibre tank mounted underneath the petrol tank. I also think the petrol tank was non-vented and that the carbon fibre tank collected any petrol spill from the main tank caused by increased pressure etc.

I also seem to remember something about a one way valve placed somewhere along the fuel line between the main petrol tank and the little carbon fibre reservoir but as I said I may be wrong about all this...

I was wrong once last week, so there is no telling if I am wrong now

But.............

I just checked the 748RS fich and the tank you are talking about is labeled as a water tank................and is in the cooling system "box". So I am pretty sure that tank is for the cooling system.

Well... up against a pro and a micro fiche it's no longer a question of who's wrong. Sorry, mate!

I didn’t want to weigh in on this because, seeing as how I’m just a few years younger than dirt, my info can be somewhat dated at times... but don’t you vent the fuel tank to the atmosphere, or do tracks require a catch system for that too now?

Signed, the old "local nag".

One question I have, Jason - does anyone make a replacement for the coolant tank behind the headstock? I think mine split again. it's not expensive, but it's a pain in the ass. I'd like to fix it once and for all.

Any reason why Ducati couldn't pull their heads out of their asses and have the supplier grind a little metal out of the mold....or make it out of glass-filled plastic?

The second question is rhetorical.

There is the Corse one that sits in front of the headstock, I have not seen one of those get split. I think they are about $100 though. And you need to run on the 23.5 setting or shorten up the steering stops a lot to clear it.

I have seen a few guys run aluminum tanks, but I don't know where they come from????

Nothing to be sorry about, there is no such thing as a stupid question, unless..................

It's about what oil to use

I have never heard of it, I'm sure the California guys will be the first to know

The 748RS carbon tank has two chambers that recycle water and just catch fuel. There are five hose fittings, 1 for water in/out, 1 for water vent (like stock), 1 for fuel drain from cap, 1 for fuel vent from cap and 1 to drain the fuel from vent tank which has a drain plug. The 998RS tank (also two chambers) is part of the front airbox. Sten, you should be able to use the 748RS one on your 998R.

Hope this helps.

The carbon fiber tank you are thinking about does mount where the stock coolant overflow tank goes. It has 2 chambers. One is for coolant overflow and one is for some sort of fuel venting or overflow I have not got it figured out yet.

The coolant tank that goes in front of the steering head that is non plastic is the old corse part. From the early 90's 916/996 vintage bikes, they went to plastic in the late 90's. It is a stainless steel part with a sight glass from an 888 right side case. It takes the stock filler cap. Very nice part if you can find one. I think it was made from stainless because at the time they were trying to add weight to the race bikes.

Mark & duc1036, thanks a bunch for clearing that up!

My wording was clumsy and on top of that I didn't know the tank could hold both coolant and fuel so it wasn't easy understanding which part I was referring to. Unfortunately I don't know all the correct terms yet, but hopefully I'll get the hang of it sooner or later.

Does this part in some way replace the standard coolant tank mounted at the steering head or does it complement it in some way?

It does not replace it. This is an overflow tank if the system overheats. It is also a vent/catch system for the fuel. You still need the tank by the steering head.

Hmmmmm....Maybe I'll contact Paul Jr. at OCC and see if he can gin me up something out of nice heavy steel - to go in the stock location....
