MD2030 fuel bleeding screw size?

Hi! Planning to go on my boat to do some maintenance. Any idea whats fuel bleeding screw size? This time trying sucking fuel rather than using that thumb killing pumping. Need to fix sucking aperatus and long way to my boat.

I don't know the size of the screw, but I have a inline squeezy bulb fitted in the fuel supply hose between the tank and the filter. Works a treat.

You can get filter heads with a built-in pump, my D1-30 has this and it makes things easier.  The "thumb killing pumping" can be minimised by turning the crankshaft until the thumb lever has the maximum effect.
