SERIES 60

The Detroit Diesel Series 60 is a heavy-duty, inline-6 diesel engine commonly used in Class 8 trucks, buses, fire apparatus, vocational equipment, and some industrial or marine applications.

A FASS may help Series 60 because its electronic unit injector system depends on steady, clean fuel delivery, and many older Series 60 engines

SERIES 71 & 92

One of the most produced Class 8 engines ever with millions of miles still on the road.
The
Detroit Diesel Series 71 and Series 92 are classic two-stroke diesel engine families used in trucks, buses, military equipment, marine vessels, generators, and industrial machinery.
A FASS may help Series 71 and Series 92 engines because many of these older two-strokes are running with aged tanks, older fuel lines, mechanical unit injectors, and contamination-prone fuel systems, so improved fuel polishing, water separation, and steadier supply can help reduce injector wear.
