I have been running 2K miles on WVO blend, and finally have clean primary filter for last 300 miles.....
But last nite I started loosing power and at idle Tach was down to 500rpm, and stalled once....
Checked the primary and pumped manually, and it looked as if the fuel was draining back into the line...and the filter wouldn't stay full.
I am guessing this is why I was loosing power, I checked the hoses and they look strong; tightened the clamps up..but still get a little extra air pocket in the primary....
Anyone have a clue what is causing this ???? What to check for???

**One thing I did notice was the 2 lines that come out of the tank on the passenger side have a rubber stopper gasket they come out through; This felt worn and soft.....
