Still a slight smell of petrol coming from the rear of the S3 despite overhauling carb and checking all pipes. Oh dear. Then I fill up the petrol tank to 2/3 and smell gets even worse. Oh deary dear. Probably got a crack in the tank. Better take it into the garage and get it up on the high-lift so we can have a look.
"What seems to be the problem then?" So I explain and we spend a good 15 mins rummaging around and eventually find a damp patch on top of the u-bend shaped bit in the middle of the tank.
"Well, I reckon you've got a crack in the tank, then." Genius. "Way I see it is: you've got 2 choices. You can either replace the tank, or never fill it over half-way." Had I been paying money for this advice I would have been less than enamoured with the depth of Dorset insight. But as it is only costing me a beer I am dutifully grateful for the dispensed wisdom and trundle off home to look up tanks on Paddocks.
Now I come to the problem. Apparently there are 2 types of tank on LWB rear-fill S3s. One with a 'six-screw sender' and one with a 'metal-clip sender'. However, because the bolts holding the tank up are really rusty, and so is the tank, I will probably damage it in removing it to have a look. And Paddocks don't stock the six-screw version any more, so I would like to be really certain before I replace it.
Does anyone know how I can tell which tank I have without taking it off the vehicle first? Or, does anyone know where you can get the six-screw version of the tank if I need that one?
TIA
Dan.
