I have a 1997 GMC 6500 series dump truck with a CAT 3116 6.6

Customer Question

I have a 1997 GMC 6500 series dump truck with a CAT 3116 6.6 liter engine. It's been stalling out. I've cleaned the water separator filter by the tank and replaces the fuel filter by the engine. I want to know if there's another fuel filter or screen between
the engine fuel filter and the injectors.

Thanks for asking your question. I will try and help you out.

No. There is not another filter. The engine only has the 2.

Can you get me the engine serial number? Cat makes a mechanical 3116 with a governor and an electronic 3116 with a computer. Just want to make sure I know which one you have.

Thanks for the information.

When you say stalling out, could you elaborate? Is it shutting off at times?

Customer: replied 1 year ago.
It's shutting off slowly like the engine is starving for fuel.

Does the yellow or red engine light come on when this happens?
