Hello guys, I want to remove my 1983 911 sc usa spec engine, I have some problems of vacuum leak from the cis fuel system, I wanted while I was removing the engine overhaul and replace parts that can be fix only when engine is disassembled.
I have a lift and all power tools to disassemble the motor

I bought several parts:
Fuel Injector Sleeve Valve
Fuel Accumulator
Fuel Injector
Fuel Injector O-Ring
Intake Manifold Gasket
Air Intake Boot.
What more parts do you recommend me to Purchase ?
What other engine components you guys recomend me to fix During the engine is taken out and i have the possibility to easily reach and repair?
thanks
tom
