Instead of doing that use a 1.5bar check valve at pump return line. Actually the return exit is just for this purpose to bleed the system. And some excess pressure when engine is unthr .
U must by pass the mech lift pump at all cost. It reduces flow a lot.
Nevertheless u might find a good solution irespective of what i'm saying

Ex: 525tds 130kW, C250TD 160kW, E320CDI 200kW, ML400CDI 230kW, A6 R5TDI 130kW
Now: Q7 V8TDI 240kW, 320d 150kW, 335d 210kW
Would not do that.. spent fuel which leaks trough spill ports is hot as fuck. So if you drive on low power there is lot of it and temperature builds up quite fast. Same goes for VE pumps, there is tiny 0,15mm orifice with spring loaded plunger for even more recirculation at high revs.
