1988 7.3 IDI

[Brian Williams]

Could someone tell me what the little square relay looking thing that is laying on top of the engine near the number one injector is? It's about a 1 inch cube with about four wires coming out of it. Can't find it in any wiring diagrams.

Water in fuel light relay.

Thank you. How does the 7.3 detect water in fuel for the light? Did they come with a different type of spin on filter than the WIX?

Yes. There was a bowl that would spin on to the bottom of the filter.
