TECH: 2017 CAN-AM X3 DRY-BREAK INSTALL
2017 CAN-AM X3 DRY-BREAK INSTALL
Fast and safe fuel By the staff of Dirt Wheels
We recently caught up with Best in the Desert race series competitor Rick Smith who has been racing a 2017 Can-Am X3 with some light modifications suited for racing. While competing in the 2020 Laughlin Desert Classic in Laughlin, Nevada, Rick explained he lost a lot of time in the pits while fueling.
The issue was filling the stock fuel tank with traditional fuel cans. His pit team tried using a high-capacity fast-fill fuel can thinking it would save some time. However, fuel can only enter at the same rate the air can be purged out. The stock tank has a very small vent system.
Therefore, when using the fast-fill can, the air purged out the fill neck, thus causing fuel to backsplash. In order to eliminate this, the crew had to pour the fuel at an extremely slow rate. It ended up taking longer than using the traditional fuel cans. Trying to fill a tank too quickly is wasteful and extremely dangerous.
We determined that a fuel dry-break system could be the answer. After many hours searching the web to get information on a dry-break install with no luck, Rick contacted fellow racer Chris Blais at Blais Racing Services. Chris had just completed a new race build on a 2019 Can-Am X3 where he installed a fast-fill system using the stock tank.
After getting some ideas from Chris, Rick went to the drawing board and designed a system using off-the-shelf parts that are readily available. Next, we determined what parts were available. Then, Rick decided to contact Hunsaker USA located in Ventura, California, and discussed some options that might work.
After making some calculations, Rick decided to order a Redhead 2.25-inch female dry-break receiver and a Redhead male dry-break probe, as well as an 8-gallon Hunsaker quick-fill, can.
The first task was to completely drain the fuel from the tank. Since there isn’t a drain on the tank, the use of a transfer pump was necessary.
Depending on the vent system you choose, consider removing the fuel tank and fuel pump. This will give you full access to mount the vent and remove any debris that might enter the tank. It is important that you place the discrimination valve where it will not interfere with the fuel-gauge float lever on the fuel pump. Otherwise, the fuel gauge will never indicate it’s full.
Removing the fuel tank will also allow you to test your vent for rollover-stoppage by adding fuel and tilting towards your vent, making sure there is enough fuel to enter the vent system. You can also secure your tank to a level surface and test your fill rate and check for leaks.
