I’m hoping someone can guide me here. I’m working on my mate’s Series 2 Land Rover, it has a supplementary fuel (petrol) filter before the carb, this is the transparent disposable type, lying horizontal. Air bubbles enter the filter until it is empty although there is enough flow to keep the engine running. I’ve filled it with a syringe but it slowly empties. I’ve replaced the petrol hose, remade the joints and fitted new clamps on the suction to the pump. The mechanical pump diaphragm seems intact and it pumps ok with the priming lever.
I’m working on the basis that any leaks on the discharge side of the pump would leak petrol not suck air.
Is it possible air is entering the pump somewhere? It is the type with a glass filter bowl on the side of the casting.
Any help or ideas would be gratefully received!
Chris
