Hello once again, this time I want to bring to your attention a problem that I found out the hard way. On one of our previous trips to Dumont Dunes, my son had the great opportunity to roll his Hisun Strike 250 at very low speeds, no damage to him or the vehicle and it landed up right as well. but one thing we noticed was that fuel had poured all over the passenger!!!. Once we got back I looked at it and found the fuel tank vent was of such poor quality that it broke at the fuel tank. Not sure if it was from the roll over or just from being made from poor quality plastic. Well, I found a great long lasting repair and wanted to share it with you all. It is something that is found is pretty much most off road race vehicles. I installed a roll over valve in place of the fuel tank vent. I am including some pics to show you. In the event we roll it over once more, the vent valve will automatically shut off the flow of fuel. It has a ball valve in it and when upside down, it blocks the flow of fuel so that it can't pour out all over the persons in the vehicle and have a potential fire! It is gravity controlled. The valves are low cost at about $15 or so. Cheap insurance when it comes to safety for sure. I cleaned out the hole where the previous fuel tank vent was. I removed the fuel tank pump/filter assembly. I then drilled out the hole just smaller than the ball check valve. I was able to reach into the fuel tank to catch any plastic that the drill might push into the tank as well. I used a fuel resistant sealant on the threads as well. I used a 1/4" NPT thread fuel tank check valve with a 5/15 hose barb. This is a much better product than the OEM product. I would recommend every one install one of these for safety if they get a chance. Or at the very least inspect your fuel tank vents. No one wants fuel leaking on them in the event of a roll over.
