I've got most of the hoses needed for the valley hoses and heater hoses replacement, but reading on the X308 forum, it seems I am still missing a few parts. Before I proceed and buy those parts and begin disassembly of the supercharger and hoses, I would like to know if it is necessary.

1. Do I need to remove the charge air coolers to remove the supercharger?
2. What are the part numbers for the throttle body elbow gaskets and bolt seals?
3. What’s the part numbers for the supercharger gaskets?
4. Can I buy off the shelf hoses to replace the hoses that go from the throttle body elbow to the charge coolers or do these have a weird bend that necessitates buying the specific part? There's two of these it seems.

 

Searching through SNG Barratts catalogue, I came up with these parts. Can anyone confirm if it is necessary to replace these when doing the valley hoses on a supercharged car:

1. AJ89646 Sealing washer for Manifold Plug
2. KSC137624 An O-ring for the throttle body elbow
3. AJ83292 Throttle body elbow gasket
4. NCC2213AC Says it's a bypass hose. From the looks of it, it goes from the throttle body elbows to the charge coolers. There's two of these. I think I can get a generic hose for this purpose this they don't have a bend?
5. NCC7723AA It's a small 90º hose that goes from one part of the supercharger elbow to the other. I think I can get a generic 90º elbow cut to the desired length.
6. NCC7735BA Supercharger outlet elbow seal. It goes under the cover that says V8?

Is there any gasket that goes under the supercharger? If so, I can't find it on the catalogue. Can I get away with not removing the charge coolers?
