It's been well over a week since I swapped the filler and many more since I last spilled any fuel (a month) so unlikely to be residual stink from that. The smell is strongest from the back end of the car so I'm starting to wonder if it is the facet pump itself that is defective but no real evidence to support that.
Running out of ideas now as there's no sign of a leak anywhere
I had exactly the same problem. Mine turned out to be a jubilee clip that was not quite capable of clamping the tube tightly enough to make a seal.
Sounds daft but have you tightened all the screw type connections on the pump/filters?
What connection do you have in to your tank? - this could be your problem as presumably the threads were cut in the soft aluminium by Marlin and may be too large? PTFE tape might help, (or whatever is required to work with petrol.)
What thread did you screw in to it?
