Does the Pump itself seem to run at a constant rpm.
The pump seems steady enuff but when I bypass it the pump and. reg. maintain about the same pressures.....like if I set the reg. to 8 psi, the pump shows about the same WHEN bypassed but the minute I plug the bypass, both gauges peg to 15+ psi.
Does anyone know what that pump is suppose to put out at max pressure... I would think that it should be well above 15 when dead headed
