best bet would be to park the car for a while and see if you get a pool of fuel under your car somewhere and see if you can work out where it coming from, from where the pool is. Or have a look under the car for any wet patches etc def sounds like a leak to me though!

only when its running, im pretty sure its not a leek, as theres no mark on the drive, and the peretrol doesnt drop on gauge when its off, it just seems to use a lot, even when driven slowly.

um i think the tanks ok, ive been under car a fair bit recently and didnt notice any obvious trouble there..

a;lso as i dsay no sign of petrol leakage on the drive, could the engine just be over fueling for some reason?

dont necessary need to have a patch it may not leak to that extent. if it was overfuelling it would have black smoke coming out the exhaust

The fuel wont come out if its leaking and the car standing still cos the fuel system is only pressurised once the engine is running so if it was leaking it would show up with engine running, i had this and it was worn injector seals
