Transducer Mounting
Just went through this with Electronics International, whose installation instructions clearly state... do not mount their pressure transducers directly to the engine, or to a manifold, but remotely, using flexible hoses. I consider the manifold prohibition unresolved, however.
I will add that restrictor fittings located on the engine have been long been recommended on this site for the engine hose feeds to the transducers, reducing the risk of catastrophic failure if the hose or transducer fails in flight.
