JPI Fuel Pressure Transducer

[timmccall]

Hopefully one of you really smart guys can answer this. I recently had a 930 installed and the avionics shop connected the wrong lines to the new i2s transducer. I have sorted all that out now (subject for a different thread) and know where the fuel pressure line will be tapped and connected but there is a differential port on the transducer. The IM does not stipulate what connects to this port, if anything.
I have a Turbo so does the upper deck pressure line connect or is it ported to outside pressure??
JPI Tech support is evidently closed for the duration of the virus.

Thanks!

Tim
