Garmin Auto Pilot Pumps

OK boys and girls, here's your Garmin autopilot pump lesson for the day.

Ran down to the R27 to install the new pump. Immediately hit a wall trying to thread the fittings into the valve body. Very frustrating, I used the exact same fittings that came out of the bad pump, threads looked correct, but I just couldn't get them started in. I finally got one started, but there was so much resistance I didn't tighten for fear of stripping out that valve body. I went home as a failure, did some snooping on the interwebs, and according to a Garmin tech bulletin pumps manufactured before 2018 were 1/4-NPT threads, later pumps went to ORB-5 threads. So ... got some SeaStar fittings on order with the ORB threads.

Man, it's just never simple, is it?
Yep, found that out last month. Threads are different!
