Smells like unburnt fuel
 

So today I let the car go past E, filled the car up and now I've been smelling unburnt fuel for 20 miles and hasn't gone away yet.

I have an aftermarket fuelpump and injectors, didn't smell any fuel from the engine bay but smelling fuel near the rear. Anyone's guess?

make sure the gas cap is on, if it is turn it counter clockwise a hair until you feel the cap lid loosen not the cap itself. Or remove the cap slowly to remove any pressure. Check all around the fuel system for drips.

It could be an issue with your evap system. Is the CEL on? Have you checked codes?

CEL's not on

Oh, maybe it was soo thirsty, that when you filled it, some gas spilt over the filler tube and that's what you're smelling.

I wouldn't worry about it unless the smell persists or you get a light...:)

<_< I feel like I'm being trolled here

I'm sorry you feel that way. That's not my intent ...... sometimes, I just joke around a bit ...... ;)

Please let me explain, if you overfilled the tank, either by forcing fill past the click off on the nozzle or the pump just malfunctions and doesn't shut off ...... some fuel can slip past the filler tube into the fender well area. Gasoline trapped in there can take a while to evaporate and can smell for some time, especially in colder weather.

PS - I don't troll people ...... sometimes I pull their leg or yank their chain .... but do not troll ..... :)

Ah, gotcha. I'll update you to see if the smell goes away I got a diffuser stuck down there so kinda hard to check if fuel is leaking around the pump.

smell the fuel again, this time I see fuel leaking rear driver side

a little information about the car, I do have an aftermarket fuel pump and injectors.

Check fuel lines, injectors connection and fuel pump while engine running

all fine, I just turned my car on without starting it and noticed a huge ass leak like a liter of fuel dripping out of my car as I moved it down the hill.

Somehow I'm convinced that all is NOT fine... find that leak! And be very careful.

My dad used to find gas leak while smoking, talk about safety

checked all the lines, also brought it to toyota as well to check, couldn't find a leak but they could definitely unburnt fuel. The leak only happens on cold starts and right after I fill up my tank.
