One of the problems is that the Üro relays look identical to the Porsche ones and it would not be a total surprise to find some dealers selling Üro as OEM ("Shall I get rid of that box for you sir?) I have bought some Porsche OEM ones from a reputable parts dealer in the UK who also sells the Üro ones at half the price. He said that the Üro ones are not advised for the fuel pump. I have sent a message to Wehrle asking if they still have Porsche round pin relays, made in Germany. I used to use an aerospace spec relay on my Ralt F2 car for the HP fuel pump. If I am still having issues, I will cannibalise a dead 5 pin relay and make it into a plug for the relay socket and fit an external 25A aerospace relay. I will use 5 core trailer wiring cable.
