Yeah, good advice about the cleaning - but new (around) 5 years ago and nice shiney plastic Tek-tanks (which are an engine out job to fit - one of the reasons I compromised on no curtains when buying )......of course does not guarantee not full of cr#p now, but I keep 'em pretty much topped up and always filter my fuel in (something I picked up from me old man, annoys some of the fuel stations as it slows the fill if a biggie - but they ain't cleaning the tank out or bleeding the engine at sea ).

Ricks right. I came at it from a different direction, Each tank holds, assuming the tank dimensions are internal, 121.03875 litres.

I get 121 litres per tank
Which equates to 26.6 Imperial gallons per tank
or 32.0 U.S. gallons

(double for total capacity).
