Just FYI: the 97-3 info was all superseded and incorporated into the TCM Manual M-0, available as a pdf from the TCM tech pubs site.

Hello Everyone,

First thanks for all your help. It was infact a bad mechanical fuel pump verified by my AME and the pump is getting rebuilt as we speak.

Make sure you have firesleeve on the main fuel line coming from the gascolator (sp) or the elect boost pump to the fuel pump and the return vapor line to the fuel manifold. I am learning this the hard way. Joe S

Circling back to some other comments, make sure your mechanic has the pressure gage assembly, SID and the IO-360 overhaul manual (M-7) to adjust the fuel pressure when you get the pump back - The pressures for the N/A IO-360 are not in the SID - it tells you to look at the overhaul manual. Its required and when I got mine back from QAA, it was way off and needed significant adjustment. If he does not have that capability, it would leave you stranded or require you to call in a mobile A&P.
