A few weeks ago, we had a very hairy experience in a rough sea resulting from engine failure caused by blocked primary fuel filters, resulting in us being rescued by the RNLI and towed for 3.5 hours back to Lowestoft.
The filters had only been changed a few weeks before, so this all points to crud in the tanks. Having now inspected the tanks, the amount of sediment etc really isn't that bad, so I am thinking of installing some fuel purifiers from MLS that we saw demonstrated at the Southampton Boat Show; here is their website link. http://www.mlsystem.co.uk/fuel/index.html
Has anyone come across these or had any experience with them?
