That is how mine functions. But, as an important cavet, you need to be careful that it does not flood the charcoal canister. The kit has you relocate the charcoal canister to inside the passenger rear wheel well. I noticed that I was getting a strong fuel smell at times. Working with Walt, we figured out that that charcoal cannister had been flooded and then clogged with dirt. It resulted in a lot of pressure in the main tank -- manifest when opening the lid when at altitude. Just watch for this issue if you have been "cycling" fuel from the primary tank back to the secondary tank when forgetting to turn off the pump. I had to replace my charcoal cannister as it was totally clogged.
NOTE: I ended up relocating my charcoal cannister away from the rear tire well.

My 12. 5 gallon tank did not have me relocate the charcoal canister. I believe the instructions have you relocate the charcoal canister air filter to the right rear wheel well and plumb it inline with the filter supplied in the kit. Another mud member (maybe radman?) said you can delete the charcoal canister filter altogether and that is what I did.
