Well. about 24 hours running, with and without the motor power, the paper & plastic fuel filter cartridge is turning pink, not so much on the paper pleats, but the plastic! Including the output nipple which should only be seeing filtered water. But no color in the tank or hoses to/from the motor. I had forgotten that the vfd is programmed to hold up the low speed torque by feeding the motor up to its FLA rated current below 1500 or so revs, so its idling when it gets hot, run it up to 8 grand and it runs about 2C above the tank. I've tape type stick on lcd thermometers on both. So maybe the motor is getting adequate cooling as long as its above 3 grand. But the flow is not improving either. > Cheers, Gene Heskett Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
