Is there a pressure difference between the Inlet and Return sides of the 017 FD? If so, could this be a reason for the engine stalling when the engine is hot?

rockreid,
The
CSV is both connected to the main fuel delivery line from the
FP for the above
FD's. Are you sure you have
FD 0-438-100-017? This is not the right
FD for your engine. The inlet pressure is higher and the outlet pressure is the low pressure for the return fuel. This is applicable to all Bosch fuel distributors
0-438-100-xxx configuration used in
CIS. You have mis-interpreted the
FD configuration for
FD-004. The
CSV could not be supplied by the return line because the
CSV needs high pressure fuel (system).
Do you know your system and control fuel pressures? The problem you are having is not attributed to the pressure differential of the FD but rather to the system and control pressures. Please post the numbers for the fuel pressures. Thanks.
