Where the dissimilar metal thing seems to come in is when there is some grounding of the metals involved. The tank would be grounded but the fittings are sort of floating out there, generally with rubber fuel line on them.
This isn't scientific, but the tank on my 27 is aluminum and over 20 years old and has had brass fittings on it the whole time, with no electrolysis. Also, in the marine business I was in it was very common to install brass barbs and shut off valves on aluminum tanks, and I don't think we had any problems from doing that. Use the yellow teflon tape and that even further separates the two metals.
I don't think it is something that you need to be concerned about.
