I watched videos and read many articles on this subject before I attempted this on my Honda EM5000SX gasoline generator. Turns out it was 90% studying the concept and 10% doing it physically. Took me about an hour with 21$ in parts from the hardware store. Add about 25$ for the propane hose®ulator because I already had a spare one. So it’s a max 50$ project and it works 100%. The beauty of this is you keep the use of the gasoline. So it become a tri-fuel generator. Follow the instructions in the video. *IMPORTANT: PLEASE SHUT OFF YOUR GASOLINE VALVE WHEN YOU WANT TO USE PROPANE OR LP GAS AND YOU MAY WANT TO RUN THE ENGINE UNTIL IT DIES TO MAKE SURE THE CARBURATOR BOWL IS EMPTY* **REMEMBER THAT IF THE ENGINE DIES THE PROPANE WILL KEEP FLOWING SO ALWAYS USE THIS SETUP OUTDOORS**
