As said std ford wiring is crap, like a lot of the other bits on cossies, a rewire is a piece of piss and a must, can be done in 30 mins making your own loom for around £5.
4wd sapphy/escos tanks still available new but not 2wd.

ps a new 4wd tank is £34.66p, but ford sell you a new hose(about £41) as it has a much larger fitting for the turbo return feed, or you could just make one ?
