+x Sonia Johal - 7 Nov 2022Thanks Dick,I’m planning this engine maintenance contingency for a five year circumnavigation and cannot guarantee the quality of my fuel. In particular, I anticipate lots of fuel can usage and low fuel levels, risking potential impurities, bugs and/or condensation.So to clarify, I ask for feedback with regards to best means of saving budget, including this PBO magazine engine maintenance contingency. My Betamarine engine already has a dual system pre-fuel filter (water-separator) as standard, annually I use RNLI recommended fuel bug solution and I always filter whenever pouring fuel into containers and especially into the tank. However, I would feel safer with a more preventative fuel bug / impurities system / additional water separation system, as extra maintenance contingency.Please would members share their opinions with regards to this PBO design, with any additional tweaks and ideas.Grateful for your kind consideration and generous advice.Fair winds,SoniaSY Salacia
