Default Fuel vent location?

Finished the wing paint and want to get all the little things finished, looking for suggestions for the tank vent location, I have seen others install the vent closer to the drain but I was thinking of this location, any suggestions?

Aww, good point, these vents have a screen on the ram air side, and a smaller opening on the back, in the event of ice or bug blockage they will still vent. Even tho I did complete 90% of my IFR training, ( had a family and had to postpone) I am going to stick to a good set of rules that one posted on here, no need to fly into IMC or known icing conditions, no flight ( for me ) is so important that I need to be any where that soon. My (plan) for this machine is day night VFR, Bad weather, stay home. O shoot, no night flight, OK maybe touch and goes......

That looks like a dandy way to drain off fuel if you park somewhere with a wing down and tanks near full (or less, depending on slope). That's why Van's has us go to the trouble off routing the drain into the fuse where a big whoop-t-do trap can be located.

I think the Harmon Rocket guys do it this way and I don't recall any complaints from them.

If you are going to vent near the wing you are better off using a naca type vent like the big iron, preferably slightly aft of the spar. No need for heat to prevent icing, less drag, and you can use very small holes to keep critters out.

Mine is going to be attached to the bottom of the wing intersection fairing.

Yes I have looked at where the vent in the tank is located, past 90% full, the vent tube is under the fule level, bad design in my eyes, but in any case of vent location, when the fuel expands, where is it going to go, is there enough volume in the fuse vent routing to accomidate this or is it still going to vent, just trying to figure this out,(havent got the fulse kit yet)
