Fuel Filters

Advanced fuel system technologies such as common rail enable mtu engines to deliver more power from less fuel – with lower emissions. These technological advancements use high injection pressures to achieve target performance levels and emissions standards, placing extraordinary demands on fuel quality. Any potential contaminant that might lead to abrasive damage at the high injection pressures must be controlled.

FUEL FILTER REPLACEMENT

A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration. That’s because enough fuel is getting through around town, but when you need more fuel for speed, enough just can’t get through the filter. Obviously, that could be dangerous if your car or truck can’t get enough power to get you out of harm’s way.

For just that reason, fuel filters have a bypass valve. When the filter is severely clogged, some fuel can bypass the filter all together. Of course that means that dirty, unfiltered fuel is getting through to be burned in the engine.

This dirt can then clog and damage your fuel injectors. Now injectors are not cheap to replace, so you don’t want to cause them damage just because you didn’t spend a few bucks to replace a fuel filter.

You know, in a way, the fuel filter can be the poster child for preventive maintenance. It’s a little part, it’s simple, and it’s cheap to take care of. But if it’s neglected, it could lead to thousands of dollars of repair bills.
