Just to close this discussion, the bike is all sorted, a while ago to be honest. Been putting alot of hours in work and forget to reply.
The pump was bad, alot of rust/muck in the fuel/tank when drained. The inside of the tank had scales of rust.
Soaked the tank in Evapo-rust , then finished with Por15 three stage kit clean/prep/seal.
Managed to get a nice looking second hand pump. I took it apart to inspect the strianer and condition (seen a few youtube videos). Frankly the pump looked nearly new , lucky there I reckon.
Everything seems good now, cheers for everyones help/advice.
