Default Fuel tank size
Does anyone know if Van's ever offered a 17 gallon fuel tank for the RV-9A. Just bought an RV-9A and builder swears it has 17 gallon fuel tanks but I have only seen the 18 gallon tanks.

Stock tank is 18 gallons. Maybe he adjusted his tank fuel pickup tube to make 1 gallon unusable.

Previous owner swears he installed 17 gallon tanks when built in 2007. All I have ever heard of is the 18 gallon tanks. Guess I will have to drain them and refill them to be positive. Thanks

Well, in all probability they are the standard 18 gallon tanks. That being said, I modified mine to 21 gallon tanks.

I am very interested in how you made that modification!

Not sure of his modification to get 3(x2) extra gallons but what you CAN do is install a 7-7.5 gallon tank directly behind the seat back protruding just a bit into the baggage compartment.

I know this works because I supplied Marvin (at the time) of Smoke Systems Helpers (I think that is the name) with the dimensions and fit tested them to 6/7/9 tip up and slider combinations.

I have 2 installed in my RV6 tip up.

I extended outboard a bay. Not an EZ process, especially for tanks already built like mine were. Somewhere in the bowels of this forum, I detailed the process along with photos,,,maybe 3 or so years ago. Not for the faint of heart.

Calibrating my tanks, they held something like 18.1 gallons and my unusable fuel was literally a few ounces.

Check out what Sky Designs offers for the RV10 & 14
https://www.skydesigns.aero/products

For the RV9, you would have to fabricate your own extended tank skins, rear baffles, mounting hardware & shorten the outboard leading edge skins.
Customization - a nasty word for some...
