  • My Stihl BR420/420C has after 15 years developed a gasoline leak. I fill tank with gasoline. Next day it’s empty. I removed tank, cleaned it up and inflated the tank with air compressor. Tank holds air without air leaks. Cleaned fuel lines. So no broken areas.
    Can someone advise me on where to look and what to replace? Submitted on 1-12-2021 at 02:11
