Updated: Aug 7

July 30, 2022


Diesel fuel tank system contamination is a BIG PROBLEM; however, very few people understand it because the unintuitive cause is complicated and its effects are mostly hidden from sight in the tanks. "Out of sight, out of mind", right? Or at least until there is a problem and then all hands on deck.

Our 2015 Leopard 44 catamaran has been profoundly effected by both disruptive and expensive damage caused by microbially induced corrosion (MIC) which has been and we hope that with the knowledge presented in this and future videos that you will help you both diagnose and fix the any issues caused by MIC and most importantly keep it from ever happening.

WARNING

If your boat's fuel tanks are currently leaking diesel fuel, no matter how small the amount, this needs to be stopped immediately as the force from a wave under passage combined with the weight of freshly filled tanks, could knock out a plug of corrosion, filling your bilge full of diesel fuel and putting your boat and lives at risk.
