My apologies, Amazondean, I automatically assumed all P80's have the same fuel pump/sender access point. It was not my intention to lead you astray. I guess we have Volvo to thank for the complexities on the AWD/XC system but clearly the chief design officer was away on holiday when they signed off on the AWD/XC. Surely they could have placed an access panel there during manufacture of the XC...?
I don't fancy you butchering your lovely XC so luckily, albeit time consuming, RobertDIY also goes in the correct route:
What a pain in the nether region
