Oil pump

It doesn't mater if the motor is running as I remember. You are also correct that the tank takes a while to fill and it isn't obvious that it is filling. You have to be patient.

Looked at my wiring diagram and it jives (as you mentioned) with what you were saying. The manual switch has it's own ECU entry port and it looks like the switch grabs a ground through the 10-pin connector.

What I don't know is the programming built into the ECU. Meaning... if the tank is full, does the ECU interpret that signal such that it will nullify the signal from the manual switch? Just thinking outloud there... Best way would be to physically try it, I suppose.

Again, using logic, if the full signal was stuck on for whatever reason but the tank ran low, you would want the manual pump switch to work. It's easy to check, pull the sensor, turn it upside down, activate the switch and the pump should fill the tank. Of course the battery switch has to be on but the ignition does not.

Makes sense. I'll have to give a try next season - just for kicks!

I will try to do the test also in the spring.

I also noticed during winter layup that it appears that some of the oil is leaking out of the main tank sender cap when the motor is tilted up.
I have had this occur before and was able to fix it by just cleaning the surfaces of the tank lip and the sender cap. I have seen where some folks pit a tie wrap around the outside of the cap. I may give that a shot in the spring.

I guess it's just the rubber cap getting old and stretched out? Yeah, if there's enough room for a zip tie, that sounds like an easy solution. Another idea, since the cap really isn't removed all that often, is to put a coat of something like Merc's Perfect Seal on the lip of the plastic to help seal things. That stuff is fantastic - never hardens up, but makes a seal against all kinds of fluids.

I'll keep that in mind. Thanks
