This site is the best. I ve got foam coming out of the top of large fuel filter also. This explains the surge and then loss of power. Blagoi's (name of shop) have never led me wrong I think with all the brake line replacement could and did dislodge the gunk that was probably preventing the now serious leak that it is. Thanks again. Brent To add I did replace the master cylinder and lines to the front brakes. I am lazy, but I still have to get out.
