Default Fuel selector

I would like to install the fuel selector FS20 type7 instead of the type2 suplied by Van's. The type7 is much more ergonomic than the 2: left tank on the left, right tank on the right et OFF on the rear.
Before to order the fuse kit I would like to know if somebody has already made this installation.

Looking at the -7 part, I see no reason why you couldn't make it work, but there are two problems. First, the fuel lines specified in the plans will not work with it as the -7 part has a different orientation of in and out ports. Second, the orientation of the mounting flange is 180° around from the -2 part. You will have to rework the mounting plate as well as make up fuel lines on your own.

I looked at it and preferred it for the same reason but if I recall correctly, plumbing is harder and not nearly as straight forward as this type. I figured I will get use to it. Time will tell.

Would a Type 3 valve be easier?

The type 3 has also different orientation of the ports and I guess that it'll be more difficult with the right entry on the front.

Luc---using a 7T valve in the RV14 'can' be done, but it will take some creative tube bending to connect the wing tubes to the valve. The 7T with the 90* elbows facing aft are at 45* to the tunnel sides. That means that the 'original' designed wing tubes would have to be changed to matched the new valve configuration. Its pretty tight in that area.
The bend after the flare would have to be very close to the aft side of the nut to clear the sides. An "S" bend back to center the aft to mimic the original design.

Grab some extra 3/8 tubing to make some patterns. Eat lunch first, you may be there awhile! Best plan is to stay with the 2T valve that Vans supplies.
