Lower Intake Gasket

Ive seen this done on 350's but no 4.3's, but can you leave the upper plenum on and just remove the entire intake as one unit. All my upper plenum gaskets are4 moths old because of a new MFI unit i installed in Jan. Im hoping all i need is a new set of Orings for the fuel lines. any advice would help thanks

Check out these select topics:

They should answer any questions you may have.

Those links should help. Yes, you can leave the intake intact, only removing the distributor and disconnecting the fuel lines at the back of the plenum.
