MFI information needed
 

I recently came upon a '72 911T with MFI that's been sitting for about 20 years. It supposedly ran fine when parked after a minor fender-bender in the front. I would like to study up on the MFI systems so I can understand them better and so I know how I should go about trying to fire up this motor after sitting all those years. I know I need to flush out the fuel tank and lines back to the fuel pump, but don't know anything on the MFI system.

Are there any good articles/books out there anyone can refer me to to read up on the MFI system? Any assistance is most appreciated.
