I know a lot of people drain their tank, and purge their fuel lines, all sorts of stuff. I just try to get it as close to empty as possible and then fill up with the 85. I’ve never had an issue. Just curious. I’ve about got it down
yea i pop off the return and run the pump till it gurgles then after about 2 fill ups i read 85%e. the first one is like e70 theres always some u cant get
