Things that I think contributed to the solution:
1. Siphoning the yuk out of the bottom of the tank
2. Straightening the pickup tube - previous damage to the tank had resulted in a slight bend in the tube and the end of the tube punching through the mesh filter. The gap between the end of the tube and the bottom of the tank might have been pretty small.
Suction on the new pump may have been good enough to lift up some of the larger pieces of junk in the tank to completely block the intake. The old red motor mech pump may not have sucked hard enough to lift the rubbish up? Not sure but either way it's working now.
Thanks everyone for your help.
Cheers
Paul
