 |
|
I have complied with the instructions to replace the fuel pump, installed a fuel pressure sensor. When flying at (at)5000 rpm I am showing about 4.2 - 4.7 psi with the electric fuel pump on. When I turn it off and rely solely on the newly installed mechanical pump the pressure drops only slightly. But other times when I turn off the electric pump it fall below the 2.7 psi alarm I have set on my EIS. The engine continues to run fine. Anyone else had similar experience?

Hi Stan,
Do you have a re-circulation line? These new pumps new them.
