Redbay 7.4 Cabin fuel tank????

Evening...........
Im just wondering if anyoe knows what the fuel tank capacity is in the Redbay 7.4 cabin rib? Ive got a sticker on mine that says its 150L but the Redbay folk told me its a 170L? I know its only 20 litres but I just need to know so that I can work out my biocide calculation.
Cheers

Well, if you always calculate on the basis that it is 150, then you will always be safe from a touring perspective.

PS What's biocide?

Diesel Bug Treatment. 150L seems very small for this type of Redbay. My old 6.5 had a 180L and was a little older. Of course, the diesel rig probably had a better range with a smaller tank...

Excuse my ignorance, Willk, it is just that IOM diesel is sooo clean we have no use for such a product and, indeed, have never even heard of it.

Well if the IOM ever changes to bio-diesel like everyone else is you will be hearing plenty about it in the future...

So, is this bio-diesel stuff the same as diesel mixed with a bug reducing chemical? I have heard some places are even pre-mixing the chemical into the fuel.
How would I know what sort of diesel I am putting in my tank?
I just put in whatever the various ports that I call at supply on the assumption that it is "OK" for my engine.
Maybe some of them are already supplying bio-diesel.
They all seem pretty samey and anonymous to me, and, indeed, are diferent colours.
Am I bothered?

Diesel Bug: Bacteria that lives on the water/fuel interface in wet diesel.
Biocide: Kills above.
Biodiesel: Fuel made from vegetable or animal oils/fats. I take it from Siochar's post that biodiesel is more conducive to bug growth - makes sense.
Currently it is legal (here) for oil companies to mix a % of biodiesel through the normal petrous diesel. The amount is supposed to be OK for fussy automotive engines, hopefully OK for Yomamahas too.
Biodiesel can be spotted as it gives the normally clear automotive fuel a slighty greeny yellow tinge, somewhat reminiscent of the urinary product of a heavy night on the shant.

Hope this helps

Aha, so Siochair's quote makes real sense now.
Thanks Willk and Siochair!

Sorry, I should have made my post clearer but wilk is spot on in that bio-diesel is a bit of a breeding ground for diesel bug. There are quite a few marina's making an issue of NOT selling this stuff. Make sure you have good filters and check them often.
