Hi Steve, it doesn’t really show the oil pan connection clearly … one drawing on the Mistral website shows the return point to be almost 1/3 of the way down from top of oil pan … I thought this was too low and therefore used the oil metering pump connection on the front aluminum housing, well above the top of the oil pan, but this requires relatively long oil return lines in my installation.
Is the Mistral return point above the oil full level of the oil pan?
I would consider welding or brazing a fitting near top of oil pan to shorten the return path if location to oil level is not so critical.

You can see it in the picture. Slightly aft and down from that black plate cover on the PSRU is the oil return line. Mistral found that the size of that line was too small and has since retrofitted it with a much larger line. The line goes directly back to the oil pan.
