I want to add electric fuel pumps to my fuel system. Right now I only have the engine mounted mechanical pump.* I am concerned that I will have no back up if the mechanical pump failed. also having an electrical pump will make bleeding and priming the system so much easier when changing filters.
However I am concerned about vacuum gauges on the Racor fuel filters. It seems the gauges show how much suction is coming from the engine driven mechanical fuel pump.
*
If I install the electric pump it will be at the fuel tank and that will place the Racor fuel filters between the electric pump (which will be pushing fuel to the engine) and the mechanical engine mounted pump (which will be sucking fuel to the engine).
Will this cause the Racor vacuum gages to read incorrectly?
