Stainless Sender in Aluminum Diesel Tank?

Howdy all!

I'm installing new aluminum diesel fuel tanks in my boat, Yay!

The only electric sender units that I can find are made of stainless. Can I use these dissimilar metals below the waterline? Does anyone know an aluminum product? I can only find Moeller units made of stainless...I'm thinking of purchasing:

Moeller Marine Electrical Reed Switch Fuel Sending Unit
Moeller Marine Electric Dash Mounted Fuel Gauge (33 to 240 Ohm's)

These seem to be my only good options at this point.

P.S. - I also installed stainless water tanks that will come within a few inches of the aluminum fuel tank end to end - any comments / potential issues here?

Normally, senders are separated from the tank by a gasket. And if you use a sealer on the screws it should seal them from the aluminum. But I've never seen a problem with dissimilar metals on diesel tanks. Diesel creeps everywhere and would most likely insulate the two metals IMHO.

And why not go plastic with your water tanks?
