Squirters may be the right size, but you may need to play with the CAM or the position (#1 or #2) of the pump cam.

I played a bunch with mine, to get a good duration shot that wasn't too much / too little using the LM-1 as the "eyes" to see what was happening. Only takes a little time in a parking lot or at the track.

I actually found that the cam / cam position was worth the most change. I found that the actual squirter size was a fine tuning measure.
