Speaking of the new tank vent....
 

I searched before posting, and didn't come up with much....

Why is the darn filler hole not in the side of the fuselage, like I think I saw on one of the prototype RV-12's?

Then we can rule out all of this talk of the fuel crazing the rear window, etc.

I'm sure there must be a great reason, but I have yet to figure out why it ended up, way up at the top? Thoughts?

Which do you suppose is more prone to splashing fuel on that new tie you got for Christmas...

- A tank with the filler hole oriented laterally and only 6 inches above the full level of the fuel in the tank?

- A tank with the filler hole mostly vertical above the top of the tank?

The yellow prototype was almost impossible to fuel with some fuel trucks because they could not be made to pump slow enough.

Potential window damage was only one of the reasons (and not a primary one) for adding the vent line

Thanks Tony, good information, what is the cost?

Hal picked up the kit at Van's and I think he told me it was $54 w/o shipping or sales tax. If you have some of the items, it looks like one could make the kit up for less.

Vent Mod
 

is the fuel tank vent mod a SB? I thought I saw someplace on the forum a picture of the install of the fuel tank vent?.but of course can't find it now. Can someone provide link to the installation picture. Thanks.

The 12 Tank Vent Mod is not a SB (yet). It is a plans revision see: http://www.vansaircraft.com/pdf/revi...Section_37.pdf

Any one got a part number for the fuel tank vent mod kit? I can't find it on Vans' web store.

Shirley,

There is no part number as yet, and it is not yet in the web store. Van's will accept orders for the "12 Fuel Tank Vent Mod" by phone.

Thanks Tony.
