Otto, My 98 Suburban with 454 V8 has one of those filter indicators. I need a new one. It's labeled Donaldson who also make big truck air cleaners. Many KW and Peterbilt trucks I drove had dash gauges for both the air filter restriction and fuel filter restriction. The fuel one saved my bacon more than once, especially in winter. We carried a spare fuel filter in the tool box.
