Gas tank venting

So here's a good one. I may be missing the "Big Picture" here, But here goes. If I vent my fuel tank through the fender on my VS won't the fuel just splash out and leak on the pavement? Personally I would like to keep as much fuel possible in the tank and running to the engine.

The overflow tube needs a check valve (one-way valve) inserted so that air can enter the tank, but fuel can't exit. The ones I use are white plastic with a barbed fitting on each end. Blow through it first to ensure the proper mounting direction. Mount it so that you can't blow through it in the direction of fuel exiting the tank. Mount it close to the filler neck so that you get as much height as possible. I think it is a 1/4" barbed fitting that is a pressure fit for 1/4" fuel hose, or whatever size hose fits on the filler neck overflow fitting. Regards, Jim

Correct me if I'm wrong.....

If you use a check valve and gas does spash over and fill up the vent hose won't the air have a harder time getting in?

I was advised to loop the hose so a 180 degree bend is higher then the filler cap. Kinda like a upside-down p-trap on a sink.

That's how I have mine vented. The hose runs up as high as I can loop it before going back down and out. By the way, I still need to get the check valve. Yes, I do smell a little gas everytime I have a near full tank and make a radical right, which is too often. I know, I know, I should have that check valve in there. :)
