2000 V70R - AWD Fuel pump and ejector (Fuel pump 9470674)

Hello,

After some research, this fuel pressure regulator appears to be very similar to 960's, 760's one:
BOSCH 0 280 160 294

I guess that it will fit in the fuel line.

-How would you test the correct functionning of the left-to right fuel tank system ?

Just an idea: can you disconnect the crossover fuel line on the RHS fuel pump (have a pan or bottle to catch the fuel) and then activate the pump by jumping the relay? It will not be an actual pressure measurement but you should see if you're getting a good flow. If you're not getting good flow, then work your way upstream. Again, just an idea.

Hi, and thanks for the idea.
I think that, if I do that, I'll have no fuel return, as the left side's retuen fuel is used to pump more and more fuel from this side.
If I take my fuel tank down again i'll try...
