I'm installing dual P-mag's in my RV-4 and thinking of the best way to get the manifold pressure. I'm thinking of installing a DISCHARGE NIPPLE AN4022-1 in cylinder #3 or #4 primer port, and use a AN FITTINGS AN824-2D TEE to split the pressure for both ignitions. Or is it better to give the ignitions manifold pressure from separate cylinders, use both #3 and #4 and skip the tee?
But what about the fluctuates in pressure? Will they affect the ignitions? Can the discharge decrease that effect? Is there an alternative and better place to get manifold pressure on a Lycoming 320 with Marvel carburator?
