Decided to not use the copper 1/8" line for the primer system and read up in VAF on what other builders have used. Three camps, Copper, Stainless Steel, Braided SS Tefllon. I decided to go the Teflon Braided SS hoses and talked to TS flightlines on the best way to run them. Put together a quick picture and ordered the AN816-3 fittings and manifold block before I measure for the two hose lenghts.
