That may be true but you can still get the information you are looking for by looking at the TCs for the engine which you have cobbled together. Most Lycoming fuel injected engines (but not all) use a diaphragm pump. That depends on the machining of the case. Continentals use gear pumps. Find out what model of Bendix (Precision) fuel servo you are using and set the pump pressure to what is called for that servo. That can be found by looking at the TC for the engine or airplane which uses the same servo or go to: http://www.precisionairmotive.com/servpubs.htm This is not rocket science. What ever you come up with still must be an approved modification.This thread is about 180s and 182s installing the Bendix fuel injection system. These airplanes came from Cessna with Continental O470 engines. So, the question was directed to owners who had performed this mod and was trying to determine what mechanical pump was being used. Thanks for the link to the feds, but being an STC mod, the information is not going to be on a TCDS.
