Diesel Brothers – Fuel Decontamination Specialists
Diesel Brothers are fuel decontamination specialists focusing on diesel bug removal, fuel polishing, water removal and fuel tank cleaning.
We primarily work with boats and marine fuel systems, providing professional on-site fuel cleaning for boat owners and marinas across Norfolk, Suffolk, Essex, Cambridgeshire and the Broads.
Our expertise also extends to heating oil tanks and on-site fuel storage, using the same controlled decontamination processes trusted in marine environments.
We do not repair engines or install tanks — our role is removing fuel contamination at the source to protect engines, fuel systems and stored fuel.
Specialist Fuel Decontamination Experts
Diesel Brothers are led by experienced marine engineers with specialist knowledge of diesel fuel contamination and fuel system cleanliness.
We focus on resolving problems caused by:
- Diesel Bug (Microbial Contamination)
- Water Ingress Into Diesel Fuel
- Sludge, Sediment and Degraded Fuel
- Repeated Fuel Filter Blockages
- Fuel-Related Power Loss and Engine Cut-outs
By addressing contamination within the fuel tank and system, we help prevent recurring issues that cannot be resolved through filter changes alone.

All fuel decontamination work carried out by Diesel Brothers follows controlled, risk-assessed working methods suitable for marine environments, marinas, residential moorings and on-site fuel storage.
