Random Fuel Smell

[etperez22]

Hello All,

I have a 92 4Runner V6 with approx 223k on it. I am noticing a random fuel smell in inside. I will then go for a drive and the smell is still there. however next time I start the engine and go for a drive it I don't smell anything. This happens once every three weeks or so.. I am still using the same fuel in it.

There seems to be no leaking of fuel anywhere. any ideas?

fuel smell

get a good light and the next time u smell it on the passenger side look behind the Plenum, the fuel Reg is there on the 3.0. they all do that when there old.When its running if its clean u might see it . problem is if u cant see it dripping but smell it , and in fact thats the location of the leak..... it might b so small that its vapor by the time it leaks.my truck had a visible leak. also the seals around the injectors get hard and start to flood out but this usually makes the truck run or start up bad.

It has been a while since the fuel smell, but it is back and I did look on the passenger side. I saw some sort of drip, most likely fuel. it was dripping by an exhaust pipe, but not on it.. is there the right location???
