I think there is a possibility that your original breakdown was caused by the fuel pump but you now have a problem that is more likely related to it not being piped in correctly, it is very easy to get the hoses crossed and this gives your "gurgling" noise, don't ask me how I know that. If you have a steady 58psi at the injector test point when the pump is running the fuel system is fine......it could be the crank position sensor??? Bunny does a replacement CPS kit by the way.
Gomog, please don't bother researching the Discovery V8 EFi pump failures, that is what I did several years ago and found out there was a problem with the Discos as well as our M3W's. That is why we developed the Walbo kit and produced all the detailed replacement instructions. The Walbro was a popular replacement for the Disco owners and it isn't a massive difference in performance to the standard pump but is more reliable with the same power consumption and is readily available. It has been proven by many M3W owners to work.
