Hi Tim,
Search for my name and rear pump.
I can't post the link due to connectivity here but somebody posted the proper testing procedure for the fuel pumps and it makes a lot of sense. It saved me having to buy another one and yes, cavitating the rear pump when the front one is off is normal.
I replaced my two relays with the ones from the dealer (better quality than the URO ones I had there) and it resolved my problem (I also splitted the power supply to the relays so it goes through 2 fuses and not only 1, there are write ups on this here)
Good luck
