Lightbulb Fuel tank leak? 🤯

Hello fellow RV-flyer:

I would like to tap into your experience building an RV12 since mine is SLSA. I noticed some fuel smell in the cockpit a couple of days ago and found this today:

Could you share your opinions about the root cause and possible remedies?
Thanks a lot in advance!
Felix

Likely from overfilling the tank and fuel leaked around the rubber hose. Happened to me on my iS too. I replaced the standard worm-gear clamps with these.

Makes a much better seal. Youíll have to run this mod past Vanís though since yours is an S-LSA.

Could be overflow spillage during refueling, worn or damaged rubber connector hose, or loose hose clamps. My first step would be to clean up the leak area, snug up the hose clamps a bit, and then monitor area for any new leakage.

Dumb question from me: have you tried tightening the clamps?

Disassemble and apply EZ Turn (fuel lube) to the mating parts.

wrong answer, if he is smelling fuel in the cockpit the solution is to find the source and fix it. never fly with a know fuel leak, especially in the cockpit.

That worked for ours as well.

I'd also remove the rubber collar and inspect the inner surface. On one of my annuals, I found the rubber has partially deteriorated where in contact with fuel. Easy, cheap to replace with newer more flexible one. (and check the tightness of the clamps)
