Who needs primers?
In the middle of installing GI-275s as EIS in my ‘77 air breathing G model and we collectively can’t determine the function of the primers. Equipment list shows them as A (auxiliary), not even optional. No normal or emergency checklist calls for their use. The fuel system and engine descriptions in the POH don’t mention them. Can’t dispatch without electric aux pumps, which we check every engine start.
We’re considering removing all the capillary tubing and the primers themselves. Any thoughts from the brain trust here on the issue? Can primers be removed?
