Could be correct depending on sensor location. Several of us have Schrader values installed at a high point in the coolant loop. Mine is at the top of the engine outlet. Very helpful for purging air after a coolant change. It also makes it easy to pressurize the coolant system, verify pressure sensor and do a leak down test

Wow, looking at that 20B on EBAY....Isn't the velocity a 4 place airplane? Imagine 200 MPH on 10 GPH!!! My 13B has yet to fly powering a draggy Acrosport 2 biplane, but I burn about 1.5 GPH just at fast idle.

I am wondering if my water pressure sensor is functioning...My system is EM3 EC3 Rd1C. On ground runs my water temp can show 180F but no water pressure..is that proper?, just expecting some pressure to develop when flying? I tried to test the system charging it with a leaky squeeze bulb (air) and did read about a 3PSI increase so am hopeful the system is working.
