The Aznew Diesel H2O Alarm provides a water detection alarm for the lifetime of your car.
Common Rail Diesel systems run at huge static pressure. The diesel, fuel temperature, water and high pressure combine to create corrosion, very quickly causing oxidisation of metal in fuel rails, injectors and creating contamination throughout your entire fuel system.
No amount of filtration or 'water traps' will protect your system from water. Water is a liquid like diesel fuel and will pass through all of your filters, carried quickly through the system by the high flow rates.
Repair bills from water damage normally start at $5000+. Install a Diesel H20 Alarm and feel confident that if there is water in your fuel syetem you will know about it.
