i think its coming from where the neck goes through the chassis.
Thats technicaly impossible - the chassis in your car is the subframe, you mean "where the neck passes through the body" right? If the cap is not sealing properly the tank will leak from the top of the neck (99% of cases). If like you say its leaking from lower down the neck (unlikely) the tank will have to come out, be emptied of all petrol and petrol fumes, filled with water and then re-welded.

yeh those stains are becoming a nightmare. does anyone know if john has one like steve at brickworx does?
Even if he does it will not solve your problem as you've got twin tanks. The rover ones are available in LH side only. The things to watch for are that the top of the neck is straight and flat and that the cap has a sound thick (petrol proof) rubber gasket that creates a tight seal.
