Responsive Engineering says it has the solution

Water contaminated diesel fuel introduced into Common Rail Diesel Fuel Systems spells disaster for the fuel system causing all metal components to rust.
Responsive Engineering explains it does so very quickly – almost instantaneously due to heat in the system – and this is then pulled at high pressure through all the components of your fuel system, causing extensive wear and damage to components that require very accurate and precise fuel supply rates and pressures.
Responsive Engineering explains that research has shown that a fuel-water separator has the ability to detect emulsified water and remove free and dispersed water as well as particles with greater than 98 percent efficiency.
It explains Original Equipment Manufacturer (OEM) vehicle fuel filters are sedimentation and coalescent types, containing a water trap, which does not cope with providing water entrapment at the high flow rates experienced in a CRD system (for example, 60 Litres/Hr for a typical three Litre engine) and thus rust and debris is continually cycled around the fuel system.
Further, it states extra secondary filters can cause a restriction to fuel flow in Common Rail Diesel vehicles because the filter medium is a physical barrier designed to trap particles.
It further states that in high pressure fuel systems typical of common rails, mechanical filtration (filters) is unable to remove all water, as dispersed and emulsified water cannot be completely captured by even the most advanced filters; such as factory fitted OEM filters or secondary filters.
Responsive Engineering states this is why water in diesel contamination has become such a significant issue for Common Rail Diesel vehicles.
It states genuine factory fuel filters are technologically very advanced and fitted with a restriction alarm, but they often prove to be unable to protect the CRD vehicle from water in diesel contamination.
Responsive Engineering says that if you try adding an aftermarket filter before the OEM filter and the restriction, it can cause the vehicle to go into limp mode. And installing an aftermarket filter after the OEM filter will bypass the restriction flow sensor in the OEM filter – but that doesn’t mean the restriction in fuel flow won’t cause damage.
The company explains that its Diesel Water Watch fuel-water seperator was invented and developed in Australia in response to the fuel contamination issues that were being experienced on the introduction of Common Rail Diesel to Australia in 2001 (CRD had been released in Europe much earlier).
The design focused on efficiently removing water from fuel without causing any restriction within the fuel system and providing the operator with a warning alarm to avoid damaging the expensive fuel system.
Responsive Engineering says it was quickly found that Water Watch also removed particulates and any other contaminants that are heavier than the diesel fuel flowing through it.
Diesel Water Watch is a verified “Australian Made” product that is specifically designed to protect Common Rail Diesel Systems from water contamination.
Responsive Engineering says “the cost of the Diesel Water Watch is cheap insurance that really does protect the diesel fuel system. If you think about it – filters are designed primarily to remove particles – not water!”
