2016 Civic - Capless Fuel Filler Question

this is probably a stupid question. but i went for a car wash today (petro season pass holder) and right after, i went to fill up the gas. When i opened the fuel filler door, there was quite a bit of soap in there. Is this supposed to happen or should the fuel filler door be sealed and shut tight? (It was definitely shut tight when i drove into the carwash). Also, every time I fill up the gas tank on this civic, it almost always overflows. Shortly after the gas pump clicks back because the tank is filled full, the gas overflows. This has not happened to any other vehicle i've owned so I'm wondering if this is just an isolated civic problem. Lastly, there's a small hole under the fuel filler. Does this lead to the actual fuel tank? I.e. any overfill flows into this hole. I'm curious because I'm assuming that it would be a bad thing given that there was soap, water and other debris there.

It's a civic. Don't keep your hopes high. Honda today is nowhere near what "H" emblem used to represent. Just trade it in for Elantra, before it gets worse.

It’s normal. The cap less filler has a cover where you insert the pump into the tank, it should seal tight enough to keep things out. The actual fuel door (that you push to open to get to the filler) is not sealed tight, nor is it on any vehicle really.. I wouldn’t worry about it.

To answer your other questions don’t take the gas pump nozzle right out of the tank when it clicks off, just wait a couple seconds and then pull it out. That should solve most of what you’re seeing overflow.

Also, that little hole is there for the sole purpose of draining excess fuel that might spill out. It’s so that the gas doesn’t run down the body panels.

The Elantra is a piece of junk, Hyundai shill.

where does the excess fuel from that hole drain into though? in the gas tank? or just eventually somewhere on the floor? if in the gas tank, doesn't take cause an issue since water, soap and debris (like sand and dirt) also get into the hole?

It drains to ground somewhere. Not sure where, but it definitely doesn’t go back to the tank.

Same issue on my Ford. After a car wash the actual fuel door is wide open, probably due to the powerful blower fans that dry your car.

I had the same concern, the filler can collect dirt and dust. And when you fill the tank it washes down into the tank.

I use a plastic cap and cover it, keeps it clean

Never happened to my Explorer in the 3yrs of ownership.

Are you the type that likes to squeeze every dollar you can into the gas tank even after it has shut off?

Detergents are great for keeping your engine clean. It's a bonus.

You mean jiggling the handle in the filler so the last bit of fuel doesn't drip on your paint?

no. i'm not. as soon as it clicks, i stop. I'm not the type to round to the closest dollar since I pay by credit anyway. problem is that as soon as it clicks, it overflows. In fact, it sometimes overflows right before it clicks.
