Out Amel 54 is 10 years old, and the fuel tank has never been cleaned. I noticed today from the dip stick gauge that there is a coating of sticky sludge at the bottom off the tank. I have no prior experience of treating this, and am reluctant to try while we are on a mooring buoy. I would appreciate ny advice on a) if this should be addressed urgently and b) how best to do it.
