can anyone help??

bought a standard 4x4 sapph a few weeks ago, it runs really well, but i can smell petrol fumes quite badly!!!

its not leaking out of the tank, ill probably be getting it set up soon, but can anyone tell me why this is happening??

 

Try checking the seal where the petrol filler neck goes through the body in the boot ? mine smelled of fuel till i sealed this, now its fine.
