Thanks for the suggestion, i followed the fuel line until i found a
banjo bolt and undid that instead of messing with the connection at the
tank, fed the line through and that gave me enough play to remove the
hatch. I replaced the pump with no problem and now hear the soft buzz
which i couldnt hear with the old one. Ran the car for about an hour
today (quite hot) and it went beautifully, also fixed up a little bit
of chugging at idle, guess the fuel pressure was too low.
