Thank you for all of your replys. My B20 engine is fitted in a 25ft River Cruiser and has the AC Delco ? petrol pump with a manual priming lever fitted. This might be an original modification by the boat builders, as is an external water pump driven off the camshaft. The reason for this type of pump being fitted is because boats often have long periods of not being used and so the petrol in the float chamber usually evaporates, so the ability to manualy prime the carb saves a lot of engine cranking. Many classic cars still have the same type of pump. I want to overhaul the complete fuel system now that the boat is back in the water. Hope that this explains my request.
