[Mgs] First drive of the year/Fuel smells

Further to Barney's notes:   if the metal line going forward to the adsorbtion cannister is clogged, pressure can build in the un-vented tank and push vapors through any of the hose connections. Bob

 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.

 The only thing really wrong right now is that my trunk smells of gasoline. Not a lot, but it’s there. The tank is new (one of those Canadian made nickel-plated tanks), but the plumbing isn’t. I suspect the filler neck is cracked. Any other likely candidates? It’s not overwhelming, but it’s enough that if I leave a shirt in the boot overnight, it has to be aired out for a while before I can stand to wear it.
