Thinking of going back to the lift pump because of WMO~

I'm surprised your having problems. I'm using the same Carter pump w/70-30 wvo blend, with no heat and no problems.
Pretty sure the Carter has a screen in it--might want to check that.

You might be right Dennis......Now that I remember......I stuck a lose sock on the end of the sending unit (inside the tank). That might be my problem!!!! I will check the screen as well. I did filter the WMO down to 2 microns before it hit the tank. I'll check that sock......
