I recently purchased a 1986 Chris Cat with twin 3.0 Pro Maxs'.
The dashboard has two Livosi electric fuel pressure gauges but not being used, what would be a good place to place the senders and get an accurate pressure reading. Never owned outboards before.

After the fuel pumps, but before the injection.

Thank you, thats what I thought just didn't know if the outboards were different.
Thanks Ron
