The problems continue

Project Blue is still giving me grief. I was left stranded in Saltaire with a blocked fuel filter. I called out the RAC (I get free membership courtesy of my bank) and the patrolman diagnosed a faulty fuel pump (they don't work when the filter is blocked!) and towed me home. I've since replaced the filter but the car still won't idle in it's own and a 1000rpm the car runs rough. I even removed the carbs, took off the float chamber covers (which I've been loath to do up to now) and cleaned the jets out. I'm going to have to face the inevitable and drop the fuel tank and clean it out. I can't see what else I can do. All I need now is some decent weather.
