Anytime, my pleasure.

It's been a few years, some of my sources are long gone, but I still
speak fluent Aztec (when it comes to maintenance).

AP of LH is a good source for oddball Piper stuff. They were the people
to go to for years for engine instrumentation issues. Piper changed the
sender/gage vendors multiple times. APoLH use to fix me up with new
sending units (and calibrated my existing gages to those sending units)
during engine R/R. We always replaced sending units and performed gage
cals when hanging engines.

Regards;

TC
