Dual fuel sending units

[Rick Fisher]

Hello


I have a 25 foot rub with a 48 gallon Aluminum fuel tank. It has 2 x sending units that are new.
One sending unit is at the front of the tank and one at the rear.

The Guages are Evinrude Icon Pro and one guage reads both sending units. The idea is that if the boat is in rough water it takes a reading from both ends of the tank.

The system worked fine for years but failed. I changed the senders but it turned out to be a nema wire.

Now I have 2 senders .. 2 pink wires 2 black wires an ADC wire which need to connect to a red and black Nema Wire.

I'm stumped.

Anyone done this?

What wires do you have going to the tank senders? Are they single wires both connected to a single feed to the guage?

The senders have a pink and black. There is also an ADC wire. The nema is simply a red and black.

My feeling was to attach the pinks to the red and the blacks to the blacks .. but the ADC wire has me confused ..
