I just installed an oil pressure sending unit and gauge on my D1-30 Volvo Penta. It only had an alarm originally. To facilitate installation of the sending unit I had to use a 90 degree fitting. I used brass and this is screwed into aluminum casting. I've later read that brass and aluminum is a no-no but also read that stainless fittings screwed into aluminum is not much better. I also read that it would be OK and to just paint the fitting and attachment point with a high zinc paint.
What should I have done to reduce any issues associated with dissimilar metal corrosion? The oil port that I used had a carbon steel allen head plug in it originally. Any thoughts on a better solution would be appreciated.
