hi iv got a mk1 gti, n its bin parked up for about 8 months, finally got it up and running and put in a full tank of petrol n went 2 my mates n i could smell petrol leaking, i looked under the car n the drive was wet, i think the fuel lines need replacing, ne1 hav a rough idea on how much this will cost, also is there fuel lines running on both sides of the car underneath?
