Hi all.
(Honda civic, 2004, auto)

I’ve never been more confused. I topped up the fuel, nearly full tank. I drove about 15min to the shop, as I was walking back up to the car I spotted a large puddle that looked like petrol (it was raining so was very obvious what colour the fluid was - pretty sure it’s fuel).
I got in a car drove back home. Parked the car, straight away see a same iridescent puddle under my car and a trail of spots on the road where I was parallel parking.
The fuel indicator showed there was only a bit more than half a tank left (which is way too much for the journey I made).

Haven’t drove the car for 24 hours and just went to have a look. No obvious signs of leakage at this point. Put the key in ignition and the fuel indicator shows about 75% full.

I am very confused as to why the fuel indicator is showing more fuel today than to yesterday and obviously I am concerned about the actual fuel leak. Should I just go for it and drive it before I get it properly checked out or could it be something very minor that’s quite common? Or maybe something that would be expected after just topping up the fuel?
Like I said the weather was very wet so the puddles might have looked like huge puddles of petrol when in reality it might have been just a few drops.

many thanks

do it smell like fuel?

In all honesty I did not smell anything, but I wasn’t really leaning over the puddle to smell it. When I had a brief look under the car I didn’t smell anything either. I did however smell fuel in my car while driving a few days earlier but it literally stopped within a minute so didn’t think anything of it.

first, check if it is really fuel.
second, inclines affect the fuel gauge (not in the quarter differences, mind you)

Check for cracks in the top of the sending unit, I think the tank is plastic on 7th gens, if it's steel check for it leaking at the seam halfway up the tank
