When I have some gophers that need killin this is how I get r done. Items required: 4 wheeler bungee cord old rag canister vacuum extensions garden hose splitter duct tape (of course) garden hose gopher that needs killin Once the setup is complete I run on idle for 10 minutes, pull hose and keep hole covered. **Note** Some of you are probably thinking that a rag on the muffler will catch on fire. Disclaimer: Mine does not get that hot, yours might. Use something else that is non flammable. I also only use mine right by the house and in the garden where there are water hoses within a few steps ready to go.
