I'm getting tired of this problem. Is there any reason why I should not put a low pressure pump in the line?

I know the AC pump works on suction supply which would be redundant but the outlet has a pressure control to stop excess flow to the carbs. The problem seems to be getting fuel to the pump. Even with a separate supply pipe it isn't being sucked through by the pump.

I've bought a new pump. A Standard Vanguard pump XP4602 which is almost identical on the bottom half except the rocker arm is slightly longer and I will transfer the top half if I cannot connect the inlet pipe (faces towards the engine block) up.

But in the mean time my daughter's wedding is now just weeks away and it's an immovable feast so my Bristol must be moveable in time!
