Primers? Why?

Issue was covered pretty good here:

Key points-

1. Primers may be very helpful in an extreme cold-start situation. But unless you plan to operate in very cold weather, you are likely safe to remove your primers.

2. Essentially, a reading of 91.213 (d) and 23.991(b) will make it clear that aux. fuel pumps are not required equipment on fuel injected aircraft:

23.991 (b): Emergency pumps. There must be an emergency pump immediately available to supply fuel to the engine if any main pump (other than a fuel injection pump approved as part of an engine) fails. The power supply for each emergency pump must be independent of the power supply for each corresponding main pump.

So yes, you could legally fly without an electric aux pump operating, but I would think only in a real pinch would you want to do so.
