Fuel Polishing question - Injector Failures

Tammy Anstett - Thursday, May 05, 2011
A common question we receive:
…“One of the worst problems we face with the reliability of our engines is the effect of bad fuel on the fuel injection system. This is true for most diesel engine manufacturers that make use of the latest technology in their electronically controlled engines. Although the manufacturer specifies water separators as primary fuel filtration (10 microns) and a 2 micron high efficiency secondary fuel filter system, we still have issues (even using the fuel they recommend) due to the quality of the fuel that is standard in our environment… We find that even with the best precaution methods, injectors have premature failures due to free water that bypasses all the systems in place. What else can we do to reduce system failures due to fuel?”
– Application Engineer

Answer:
We understand your problem and agree that today’s high-tech engine fuel systems have an Achilles Heel - Water.

Our fuel polishing systems, utilizing Separ Filters, remove up to 99.9% of all water and particulate. The best way to illustrate the need for and success of these systems is to showcase the following case. This photo below is from the U.S. Embassy in the UAE taken by Embassy staff.

Their problem was similar to yours in that they had fuel deliveries that were badly contaminated with water. This water destroyed several Cummins injection pumps and countless injectors. The picture (below) is the before and after just one (1) pass through our fuel polishing system. Since they started using the Portable Cart system, they have not had a single fuel-system related failure.
