Inlet Manifold Off

Inlet Manifold Off
Having sort advice left, right and centre it appears that the Inlet Manifold will need to come off to fit the new silicone induction hose . The WRX intercooler is on and going great guns. All I need to do is the undertray and fit new rubber seal.
Now this Inlet manifold is an area that I have ventured into yet, so I am after some advice or a "This is how you do it" guide. An extra pair of hands would also come in handy if you know what your doing too . I may even re-paint it while it's off.
Are there any gaskets etc that I may need to renew? I have access to a full work shop.
Big Brakes, Lee, Si, anyone?
Bacon Butties on me.

To remove the inlet manifold isn’t too difficult make sure you disconnect the wiring harness from the various sensors. Also when removing the fuel lines disconnect the battery.
Parts to disconnect
1. Fuel line supply from fuel filter
2. Fuel line return
3. Petrol tank breather to emission canister
4. Wiring harness clip near battery
5. Water temperature sensor connector for interior gauge on cross pipe from radiator
6. Water temperature for sensor connector for ECU on cross pipe from radiator
7. Knock sensor connector from top of block near piston 4
8. Oil pressure sensor connector above oil pump
9. Water header tank
10. Throttle cable
11. 4 bolts either side of inlet manifold
12. Brake booster pipe the servo (nearside on top of inlet manifold)
13. Emission canister blow by pipe
14. Breather pipes off each cylinder head
That’s roughly all the various pieces to disconnect, once the manifold is unbolted disconnect the two water temp sensors, oil pressure sensor and knock sensor connectors form underneath the manifold. If you respray the manifold use an etch primer this will prevent the paint flaking off like the original Sti paint. With regards to gaskets if you fit inlet spacers you need four inlet gaskets and a new throttle inlet gasket.

if the manifold is off you could also go for carl davey spacers which as kev said it would be rude not too
if i had time on my hands i would give a hand but im so busy with mine and starting the new business
