Audi 100 Quattro Petrol Tank Replacement

[mortcars]

the petrol tank on my barginous Audi 100 S4 is a gonner, it wont hold over a quater of a tank and then its fumes all the way so the petrol evaporats.

ive sourced a second hand tank but the local gaurages are quoting a min of 600 and a max of 800 to do the work. which I cant afford.

aparently the cost is due to having to remove all the rear quattro system that the tank sits over.

so what do I do???

cut my losses and sell it on or save to repair??
