I had an Echo chainsaw that was missing a gas cap. I ordered a 1 x Cap - Black (P021011590) from the website. A few days later a package arrived and the gas cap was nicely packaged inside. I proceeded to pull the 1 x Cap - Black (P021011590) out of the packaging. I placed the saw on my workbench with the mouth of the fuel tank facing upward and carefully added a few ounces of non-ethanol gas. The next step was to pick up and screw the 1 x Cap- Black (P021011590) clockwise approximately three turns until it was snug.
I then picked up the saw and placed it upright on the workbench and no fuel leaked! The 1 x Cap - Black (P021011590) performed to spec. Project complete and mission accomplished. Thank you eReplacementparts.com! We did this together!
