I have been wanting to do some reworking of my return line setup (stock 12V setup) and it's just a little weird. Now my question is, do the 24V's have the return for the injectors going straight back to the tank or do they somehow end up back in the inlet side of the VP44? I don't even remember seeing any return line things on the 24V injectors so did I miss something or what? The 12V engine dumps the injector return fuel straight into the fuel filter, so the whole return line setup remains at inlet side pressures. The only return line that has no pressure (goes to the tank) is the one on the P7100 that dumps excess fuel from the lift pump. Basically I want to get rid of the injector returns going to the fuel filter and dump them straight to the tank instead, but don't know if it will cause any issues since they supposedly need that inlet pressure for some reason, though the 24V uses the same injectors (with different top part) thus getting to my question above.
