My fuel rail's been leaking so I'm in the process of replacing it as I type. (yes my keyboard is now filthy)
I was reading a previous post that was archived and not available for comment so here's a new one:

I've been through so many pages to find this one that I lost track of the post in question but it spoke of the updated fuel rail and its new mounting and retaining system.
1. There are two indented slots on the injectors above the connector. It said to slide the retainer into the slot of the fuel injectors nearest the 'tail'. What tail? There's an inlet, an outlet and a connector. Now one slot is a complete ring around the body of the injector. The other is a pair of slots down either side. As it seems I may not get a reply before I have to reassemble, I will assume the slots nearest the connector (is the wire what is referred to as the tail?) as they seem to be the best fit.
2. Two of the fibre washers on the nozzle end of the injectors popped off. I found them but they both cracked whilst snapping them back on. Problem? For now, I'm just putting them back in.
3. Lube on oRings? WD-40? Motor oil? Lithium Grease? None?
4. Are oRings available seperately?
5. Is there a book for the 96-98 940/960's? I've not been able to find one.

Thanx for any and all info.
