Help... new to me 21 HP has a couple hiccups.. the Speedo and water pressure gauge not working. I think its this sender (mechanical to electrical). The Speedo has a pressure rating of 200 psi and the water pressure at 30 psi. What are these called and where can I buy them.. no numbers, just psi stamped into them.
Tested the two gauges by adding direct ground, which pegged both (independently), so I think that means the gauge is good and sender is bad?
