Fuel leak woes
Right... I will try to explain the best I can. Car been stood 2 years in garage. POLO 6N 1997
Did a new build during that time, painting engine bay etc.
I turned on the ignition to check fuel supply is working and yes it was. Fuel pumping through into a can and the return line working aswell.
I then smelt petrol. Looked underneath and saw fuel pee-ing on the floor form under the tank. Turned off fuel supply and the leak stopped. Tank is
almost full.
I then realised the leak was coming from back of the tank onto the anti roll bar. I believe this is where the fuel filter it.
I then switched on fuel supply and again , as soon as I switched it on. Urinating down on the floor.
The pump is within the tank. The only thing that is external is the tank it self and the fuel filter.
Why would car being sat for a few years cause a fuel leak. I'm sad because I can't move the car during the engine build, can only get
stand jack in from one side.

It's probably a hose broken down,the ethanol in modern fuel destroys the hoses.

Seen more than a few alloy bodied filters corrode through as well as rusted fuel lines , 97 may be plastic ? Best bet is to get under the car and
check but don't get petrol in your eyes or even worse your ears.

I hope these exploded diagrams help
also I think you can get the pump out of the tank in-situ from above. (but as you say its most likely the filter or associated hoses )

Thanks for much. I will give these to the fitter who's coming around to replace the filter. I had a look at the top and the pump is fine and the
hoses at the top also.
I think the tank feels plastic there for must be filter that must be corroded.
I can do job myself but i'd rather pay £40 than get under cars to get drenched in petrol.
