MG MGB Technical - Smell of gas in the boot (trunk)

Looking for some ideas on where to start tracking down the cause of the gas smell in my trunk. 79 B with a brand new gas tank/sending unit/gaskets...etc. Recently rebuilt ZS carb that seems to be working well. Desmogged per Twist but all vacuum lines to absorption cannisters still intact. Can someone point me in the right direction on where to start.

Frank-
Start in the most obvious places: recheck the fuel line connections at the fuel tank and the fuel pump, then the hose that connects the fuel filler and the fuel tank, then the vacuum lines connections at the fuel tank.

After checking what Steve S. told you;
When I had this problem on my '78 B, it was from the fuel pump diaphragm leaking and fuel exiting via the hose that goes to the passenger side rear inner fender area (US spec). Took me a while to find it, but I was most gratified to have a new fuel tank and lines, etc... after viewing the Swiss cheese look on top of my tank; as I've read here before, keep the fire extinguisher handy!

Regards to all,

I had a similar problem on my 80 roadster. The cause ended up to be the rubber hoses which lead to the vapor canister in the right rear. The hoses were somewhat brittle and there was a small crack near the end of one hose. I cut it off and reattached it but the gas odor remained. I guess there was another crack - it seems that the gas vapor can seep through the smallest cracks. I ended up replacing both hoses and the smell went away.

Should the hoses in the trunk to the vapor cannister have clamps...mine are simply slip over without any clamps on the rubber hoses on both sides of the cannister. BTW the fuel pump is new (solid state).
