Re: smell of petrol inside car
Ah ... South African pump attendants...
One of them (at a Shell station) tried to lever out the restrictor that prevents a Leaded petrol fuel pump nozzle fitting into an Unleaded fuel filler neck - they had no unleaded and he thought I wouldn't mind leaded instead.
Good job I spotted him before he wrecked my (catalyst equipped) hire car but the point is, don't take any notice of those ****s.
If you have a smell, you have a leak. Period.
If it does it all the time it's likely to be at the tank, or in the lines to the fuel rail. If it does it more when the tank is full, and less when the tank is empty then it's at the tank or filler end.
Check the lines, particularly those in the engine. The standard fuel pipes may be perished
If the pressed-steel clips on the hoses have been replaced with Jubilee/Terry etc. clips then these may be leaking. They seem to come unscrewed with the pulsing you get in the fuel line. If the fuel line isn't hard plastic - if someone replaced a line with a softer (for carburrettors!) line, these pulse more.
Turn the engine on and get in the bay looking for seeping at any of the joints.
Continue searching.. under the car back to the tank. There's only a few joints. If the engine is running, the fuel leak will be more obvious as the system is being pressurised but you'll be surprised how little petrol makes a big smell.
Check the joints around the tank - particularly the fuel filler pipe as that has several joints.
It's unlikely that the tank itself will be leaking but what about the cap?
My money is on the sender unit. It has a rubber gasket sealing a big hole in the top of the tank. The cover is probably held down by bolts... they'll be loose I'm sure, allowing the fuel to leak. You'll just have to re-tighten the nuts and glue them locked. I don't know where it is in the GTV - I suspect access is under the rear seats (hence the smell in the cab). Again though...smell would reduce when the car is "closed" or when the tank is empty.
If there's a leak behind you, you'll notice the smell more when the windows/sunroof are open. It'll go away when the windows are shut.
Anyway, it almost certainly isn't an "air-lock" in the tank!
