Oil Pressure Sender
Discussion
I have a new one of these waiting for me at the local Royal Mail Sorting Office (thanks Joolz) and I hope it's got some instructions with what to do with it in the package, but just to give me some extra help has anyone got any pointers that may make my weekend go a bit smoother, I don't even know what it looks like or where it fits 
Just fitted a new sender myself. Assuming your engine is similar to my own (4.5 serpentine) here goes...
The sender is located on the bottom of the engine just in front of the sump. You need to raise the front of the car on ramps so that you can crawl underneath. You might get away with simply jacking up the car, removing a wheel and reaching underneath, but ramps are easier.
Remove the electrical push-on connector attached to the unit. Use an open ended spanner to undo the old unit. (Check the spanner size on the new unit)
TIP - Have a piece of blue-tak or plasticine handy so that you can plug the threaded hole when you remove the old sender otherwise oil will drip/run everywhere. Put some papers under the car so that you don't oil stain the garage floor.
Before fitting the new unit wrap some PTFE tape around the thread. This will ensure a good oil tight fit. I didn't the first time and under pressure oil p**sed out everywhere when the engine was running.
Reconnect the cable and start the engine, hopefully your oil pressure readings are now normal.
Finally, when the car is back on the level check the engine oil level via the dipstick just in case you lost more oil than you thought.

Cheers for that, it's a 4.0 Pre-Serp but I can't imagine it being too different
I imagine Joolz has packed the unit with similar instructions but not even knowing where it was, I was dreading the first line to be 'remove the dash top' as this requires a call to my alarm fitter as they kindly fitted something somewhere that causes me a bit of a headache
Anyway, sounds simple enough, cheers for the heads up about the blue-tac, currently serching the office for some to steal

Just been thro the same process, changed the sender and still reading 60 to 90so had to change the gauge and it now reads 35 to 40 when running. Before I changed the gauge I coupled up an oil fed gauge to check what the exact pressure was (it showed 40) so I knew to go for the gauge and not the engine.
