2007 S80 3.2 fuel pressure sensor removal

[coded9]

So I've made an few attempts to change the fuel pressure sensor, but there is so little clearance between the screw holding it on and the engine. I tried an slimmer offset screwdriver, but no dice there. The only way I've even been able to get the bit on is using my bare fingers, probably 2 mm at best after the bit. I wanted to know how has anyone managed to get the fuel pressure sensor off on an 3.2?
