When I bought it was just a hole with the return line Loosely gong into the Tank. All I did was used a piece of vacume hose a Inch or so and Ran the line through it and put it in the hole of the Tank. That plugged it up. You would never know it even looking at the pic. you might now that I told you what to look for

Clemsonfor just stated he leaves his cap loose which i new of the Pressure build up problem if the tank is not Vented. Thats why I used the old ATV fitting to prevent that from happening. I actually could see bubbles coming out and then I realised where the Fuel was coming from esp. when it had a full or nearly full tank. I'm From WV. and Ohio and know the Climate and IMHO you need to set up your TS. I can show you my On Cheap setup that works great. One of my Better Ghetto Rigs. Trust me there's some that I not so proud of :laughing: All your expense will be for the Igniter if its not there. If it's not all your have to do is remove the Bolt and screw it in and run power to it which can be done alot of different ways. When I first set mine up I just used a wire straight to the + post on the battery. But when I found out how well it worked you can see I ran it Through my Ign. Switch.
