Ethanol effect on fuel filters
Posted: Wed Jun 09, 2021 10:37 pm
This is just a wee warning to anybody purchasing fuel filters for their machine.
I have been using the little square plastic fuel filters manufactured by 'MRC', as they fit neatly out of the way in the confined space on the Yamaha SRX twin shock and Monoshock that I run. I have also fitted them to the '74 450 MKIII and a Moto Morini 125H. The latter uses 'SuperUnleaded' because of it's 11.5:1 compression ratio from the use of the "Heron" cylinder head.
Both the white filter from the Duke and the blue filter (was green!) from the Morini, show deformation of the filter element, so that it is no longer effective and the resulting contamination of the fuel may also be affecting the running of the engine.
I attach a couple of images that demonstrate the problem.
Good health, Bill
