I am re-plumbing my fuel supply system and have concerns over the fuel return to tank line.
I have a Ford 2712E 80hp main engine, a 4.2kva Panda type generator with Faryman engine , 2 main fuel storage tanks and a day tank.
The engine and generator can draw fuel from any tank, I would like to return the fuel to the tank it was drawn from. I've sorted the plumbing and now have both return fuel pipes tee'd together and returned to the correct tanks, my worry is that when just one of the engine/generator are running, the non running engine will have positive pressure one the wrong side of the fuel return port. Is that a problem, could I end up with fuel flowing back through the injector pump and would it be a problem if I did. Do I need to fit non return valves, if so, what sort of pressure should they operate at.
Thanks
Nigel
