For quite some time now I am trying to understand where is located my fuel transfer pump on my engine.
I read all the manual for Hercules engine D3000/D298 on which my engine is based and the manual mention a fuel transfer pump, either mechanical or electric that pumps fuel from tanks through filter and to the roosa master injection pump.
However, I checked, rechecked, and checked again, and I cannot locate any fuel transfer pump on my engine, neither mechanical nor electrical.
Is it possible not to have one???
For what I found, my setup is fuel line from tanks going to tank selection valve, to fuel filter to roosa master injection pump.
This another mystery I am trying to solve
