Re: Dare I…ask an Etec question here?

I really don’t know. I’d just do it as a gallon of the minus 50 is usually less than 5 bucks at wal mart or any auto parts store. I just put enough thru to see pink out of the water intakes. I use a Camco RV hand pump to put it through. Also, make sure to use a set of ear muffs on the water intake if running out of water, as the rear flush attachment is made to be used with the engine not running.
