WOW. You sure have the illustration thing nailed. Nice Job.

If you have sufficient resin to perform the repair. I say no to more resin equals more pressure. Pressure is a result of force applied on a substance weather static or dynamic and in the case of our injectors, the inside diameter of the of the tip seal is a factor as well.

Now if you do not have enough resin in the injector to allow constant contact with the injector plunger in the pressure cycle, you will not be generating any pressure and therefore may not completely fill the break.

To much resin on the other hand is just that a waste. I use the old style glass dropper pipets and like to fill it to just slightly past the radius at the tip. On the rare occassion I have a chip that likes to drink I unscrew the injector in the pressure position and add resin as needed. Then reinsert the injector plunger in the vacuum position and carry on. I think point points A & B on your illustration was meant to be the channel for a UV mini shield.

Take what I have said with a grain of salt as I am surely not a fluid dynamics expert. I am sure Brent can expand more on the design of the injector and seal.
