I was poking around in the shop tonight, wondering what to do next , and started examining the fuel injection system. All I have done to this point is install the fuel servo and the mechanical linkages on the servo for throttle and mixture. I was looking at the spider, or flow divider mounted on the top of the engine and noticed a fitting with a plastic cap. As it sits now, there is one firesleeved line coming up through the cylinders on the right side that appears to be attach to the fuel divider, then the lines out to the 4 cylinders. Looking down from the top of the engine, the fuel line is at 3 O'clock, and this capped fitting at 2 O'clock. a quick search through the literature that came with the engine and a visit to Precision airmotives website didn't offer any answers. What is this fitting for? It's only capped with a plastic cover, so it must do something. Where can I find this info
TIA
