Hello Jesse, Thanks for your input. JF has a TCM (Teledyne Continental
Motors) IO-240 engine in his airplane so factors relating to either the
Lycoming fuel injection system or a carbureted engine do not apply.

Hello Tim, Thanks for your input.
JF has a TCM IO-240 B_B engine. I don't know the specific dash number.
He does not have a leak problem like yours, but an apparent pump output
problem according to the authorized mechanic.
JF is in Germany so he is a long way geographically and communication wise
from the TCM factory and apparently has access to only limited local TCM
support.
