Thanks Scott.
Unofficially, I calculate approximately 50 more minutes of fuel endurance for the 912is RV-12. That's figuring both tanks have a capacity of 20.2 gallons. |

The official capacity of the tank in the first version (912ULS) was 19.8 Gal, so the new airplane has almost an extra 1/2 gal.

It varies.
Some times just a couple, and other times (as in this case) up to 5 at some points.

Thank you.
Recalc in progress!
. . . . . . . .
New numbers . . .
Unofficially, I calculate approximately 55 more minutes of fuel endurance for the 912is RV-12. That's figuring old tank capacity and new tank capacity, at cruise fuel flow.
In my humble opinion, I'd say that is significant for the RV-12. |

Anybody know if the new tank can be used with the old fuse?

Filler neck not in same location - more underneath window. In fact, looks like more difficult to fuel from handheld cans because location is more over center of wing.

Yah... right now I can put a furniture pad over the top of the fuse, set the can on top and let it fill the tank. With the new location I'd either need to pump it in, develop better biceps or work out some sort of hose arrangement... not sure how that would work out. Probably more convenient if you fill up from a gas pump, but a lot of us schlep it in 5 gallon cans.

Use a "jiggle tube" directly to the new fuel port.

Looks great, love the electric flaps and the center console, I really wish they had moved the fuel to the wings, still the only item on this aircraft I don't like.

I figured an iS powered -12 must in the pipeline a couple years back. The economy gains along with less maintenance and carb fiddling is clearly what the people want these days. The time will come soon where no more carbed 912s are being produced.
One of our Rotax vendor shops no longer builds custom 912s with carbs any more as of a couple years ago. They work so much better with EFI.
Glad Van's was listening. I predict more sales as a result, despite the higher price of the engine.
