Today, I changed the two fuel filters on my wifes 85 300D for the first time. I filled the big filter with Red Line and bled the system. It fired right up,and after the temp came up I ran it pretty hard for ten minutes or so. Alot of black blew out the exhaust and it really runs better.

However, I still have two small bubbles visable in the primary filter. One at each end. I tried to pump them out,but to no avail. I had fuel coming out of the pump but no air out of the bleed nut,so,I buttoned it up and she runs fine.

Am I O.K.?
