Would any Members possibly direct me in relation to the size of the '' bearing '' inside the '''plunger'' on the below image . Top right in the image provided . Brass plunger has a hole in the base , which enables the bearing to ' swim ' whilst fuel enter other holes , on its outer sleeve allowing fuel to enter , hence in between strokes , the bearing settles , then seals the hole in the base ..Well I assume that is how it works ..One can just see a dark spot at its top just under the cap , so the pin can be driven out to remove cap and expose bearing .
