Has anyone experienced fuel leaks from the front of their Tuscan? I seem to have developed a leak under the radiator area which seems a bit weird as I didn't think any fuel lines went that far forward!

From memory, I think there is a fuel vent pipe at the front of the car, that vents fuel if the tank is too full. When I bought my car, the dealer told me to only fill the tank to the first 'click' of the pump nozzle as brimming the tank would cause this.

^^ Yes, the vent is from the "carbon canister".

The device takes vapours from the fuel tank and when these condense, allow the liquid fuel to purge back to the engine. Overfilling the fuel tank 'overwhelms' the function of the canister and has been known to cause poor running/engine down on power.

So - not unusual....but indicates too many brimmings of the fuel tank.

This happened to mine after i filled the car up on a warm day. Must of been a bit of expansion in the fuel tank and pushed the petrol out of the carbon cannister . Mine is on the drivers side of the car behind the headlamps

That's relying on a +/- 2% accuracy on a TVR fuel guage......I tend to take it to "about" 50 and no more biggrin

Thanks all, great relief. I'm usually very careful when fuelling but must have over fuelled. I'll return the large wad of cash to the bank!

...this just happened to me yesterday in my TVR Tuscan - although my circumstances were a little more complicated.


The boot catch had not been working properly for a few week and unknown to me I have inadvertently not closed the boot after parking the car over night. The result was a drained battery due - I suspect - to the halogen lamp inside the boot being on. ...Halogen lamp since removed.


I jump started the car and warmed and it for a hour. I then filled the tank to the first click on the fuel nozzle and took my daughter for an ice cream. The weather was scorching yesterday and I left the engine running for about 30 minutes after refuelling when, suddenly whilst idling, the car started to cough and splutter - then died.

My attempts to restart the car were interrupted by someone telling me: 'er mate, you do realised your car is leaking petrol from the front bumper??!!'

Quite a lot of petrol leaked onto the road and this resulted in a fire engine turning up with siren on and blue flashing lights.


When I opening the petrol cap a lot petrol came gushing out - fortunately I had a large towel ready to absorb the leak before the petrol dripped onto the hot exhaust pipe below.

Trevor ended up on the back of the recovery vehicle and spent the night in the garage (my garage as its Easter weekend).

This morning i syphoned 6 litres of petrol out of the tank and ran the car for an hour in the garage - revving the engine like a 'nutter neighbour from hell'. There were no further leaks so I'm putting this down to over-filling the car on a really hot day.

This forum was really helpful to me - I was quite worried about a leak from the front bumper and though it very odd - until reading this post. Thanks to those who contributed.
