Digital panel meter under $10 with shunt on ebay. Need to custom mount.

Hey! That looks like it might be the ticket!
Is there any idea what the maximum current draw might be for the in-tank and high-pressure fuel pumps?
current in the motor will drop, ONLY if the hot pump has an open circuit
a hot pump 'Stall' with out open circuit, will Increase current drain
and the pump motor will get hotter
Yes, I would assume maximum current would be at zero RPM (stall). So one would need to know the proper operational range of current draw.
Since the RV runs properly most of the time, I should be able to easily determine the normal current draw using the above gauge or a clamp-on gauge.
So now all I need to know is the stall current for the pumps, so I can use an appropriate gauge and/or shunt.
