Granby "Rhino-Tuff" tank (similar to Roth) but with cast aluminum connections

Is there any issue with connecting the incoming metal pipe to cast aluminum threads? Does it require special fittings to prevent galvanic corrosion? There's a galvanized steel fitting that attaches to the cast aluminum threads.

Since it is for fuel oil it must be approved for that purpose. I would install it in accordance with the MFG instructions.

I'm getting bids for a tank replacement, and just didn't know if that would be an OK design to consider.

Granby sells a lot of tanks as does Roth. I wouldn't be concerned.
