The lift pump in Diesel911's post looks like the one on my "M" pump but maybe those were fitted to some "MW"s as well. I've never been into one as I cheated and bought a replacement for my previous MW. I recall it wasn't too hard to remove and I'm thinking I used a 1/4" drive set to do so. The sockets are pretty thin walled and it seems like they fit OK. Been a few years so I might be absolutely wrong there......
