[Mgs] First drive of the year/Fuel smells

[Barney Gaylord]

Check the filler pipe rubber connector hose first.

Late model MGBs have fuel vapor recovery 
system.  This includes an expansion tank high 
inside the RR fender (in the boot)  with a flex 
hose between the expansion tank and the fuel 
tank.  This hose appeaars to connect to the boot 
floor near the filler pipe.  If this hose leak it 
will spill a bit of fuel into the boot, especially just after filling the tank.

There is another connection to the expansion tank 
going forward.  If this one leaks it can 
contribute fuel fumes into the boot space.

The later model MGB also has flat top fuel 
tank.  These tend to rust out on top like Swiss 
cheese, then will spill fuel from the top surface 
with the tank is filled or near full.
