Yes the squirter is on the left if looking from the front of the motor.  If you are working with a stock parts, the piston has an arrow on its top giving the direction also (the arrow points forward and is located on the piston's top in the forward most location).

FYI: In the manuals, the convention is to look at the engine from the back when assigning right and left.  So using this orientation the squirter would be on the right and the numbers would be on the left.
