where does the petrol go?

[tdko Lurker Find all posts View Profile Close tdko]

I have a duel fuel system and where I filll up there are two outlets one for main other for sub.However I was curious where the petrol goes if it does go into either spout but just the incasing. Does it find its way to the main or sub or just lies in the body of the car. Could someone please let me know.

I've often wondered that too... but that's as far as I went with the thought

Re: where does the petrol go?

You really want to know?? Ok I'll bite

The front one fills the sub tank, that lives in front of the rear axle on the left hand side. The rear one fills the main tank wihch lives behind the rear axle.
the guage for the main tank is in the instrument cluster with the speedo and tach etc. the guage for the sub tank is next to the radio.

Amazing what a couple of letters can do to the interpretation of a sentence

I'm pretty sure it has an overflow pipe that joins back onto one of the main pipes, (had the interior off once to do some minor panel beating) can't tell you which one off the top of my head, but it doesn't just go into the body.

But you see people putting their fuel caps on, and then washing the area out with water (at least I've seen it many times). In which case that'd let water into your fuel tank... so I'd be guessing it just runs down onto the body. It's not gonna do any harm, exhaust is on the other side.

*shrugs* I was going to have a look again today, but it slipped my mind till I read this again tonight, lol. But I am almost certain it has an overflow pipe (unless I'm thinking of my 4Runner), although I can't imagine it'd just run down inside the body, or you'd smell petrol inside every time you had a spill outside the filler spout until it evaporated.

Re: where does the petrol go?

Just went and had a look at my 90,it will definatly not run into the tank or the body,more than likely if it runs away inside the filler door, it will winde up on the ground.Otherwise it will simply flow down the side of the car onto your foot.
