Fuel Tank Issues

Stopped by dealer today. Bottom line- no fix yet. They acknowledged the problem and narrowed it down to this little check-flow device that is apparently a government requirement now. The valve is actually inside the aluminum shroud in the picture, I didn't think about snapping the photo until it was put back together. Their theory is that backpressure from escaping air as the tank is filling is closing or restricting that backflow device enough to trick the gas pumps into thinking the tank is full and therefore shuts it off. They said I could remove it but they aren't allow to for liability reasons. I haven't gone that route yet, figured I will give them some time to get a response back from their technical inquiry to Skiers Choice. Short term fix is to fill the last 10 gallons with gas cans...Ugh!

These things can go bad. Just have them replace the valve...

You can see the check valve in this pic. I removed the aluminum shroud when I pulled my fuel tank.

This pic shows the vent setup.



What you can't see in these pics, is the charcoal filter that these vent lines go to. It is under the driver's side gunwale behind the tower mount and in front of the gas fill. Between the small combined vent and the charcoal filter, the displaced air takes awhile to escape the tank. The previous years did not have the check valve and charcoal filter. That is why gas would shoot back out when filling at the pump. So they fixed that issue, but now it takes longer to completely fill the tank at the pump.

I think I would probably replace the filter with something that breathes better so air can escape faster. Seems like a simple fix.

I actually removed mine and it barely helped. Venting is just too small.

I was at the lake this past Tuesday and the fuel gage needle was resting on empty, not even bouncing. When I filled it back up, I set the handle on the slowest locked setting to try to prevent as much sloshing in the tank as possible. It cut off at 35 gallons. I have a '16 Craz with a 49 gallon tank. It took me about 10 minutes of feathering the pump but I got 48 gallons in it. This is a pain, especially when you have a crew waiting with you to get to the water, but if you take your time and have the patience, it will get full. The needle was completely on full, not even bouncing off of full with the rocking of the boat and stayed that way for probably an hour of wakeboarding and surfing before it began bouncing off of full.

Managed to have everything set just right at the pump,we ran the gauge to e as well and it was there for a bit , and with no mods to the fill system managed to get 47 gallons in the tank, using the same method , there have been times where depending how the boat is sitting at the pump that even with the slow feathering method we only seem to get it 3/4 full , but for the most part the above mentioned method seems to work well for us as well

Thank you for the thread, it explains what I'm finding. We recently got an 2006 Outback and it was frustrating trying to fill it up. We manged to get probably 3/4 full but then gave up.

Another option could be to fill the last 5-10 gallons from a can. Still annoying, but maybe it's better? (Use a siphon to make it easier, just don't overfill because those are moving lots of liquid very quickly. https://forum.moomba.com/showthread....ecommendations)

Thank you Greg for the advice, I'll start with one can for the top up and see how how far the gauge goes. I guess this is trial and error but hopefully not too much error.
