Please note before buying that there are approx. 26 different versions of the base gaskets used for the Rochester Quadrajets so look carefully at yours and compare it to our pictures to make sure it is the same before purchase. If you have any doubt message us your carburetor model number and we will see if we can help.We will be adding others as we stock them.

This is a  1/16 inch thick paper carburetor base gasket used on some of the Rochester  Quadrajet 4 barrel carburetors.

One distinguishing shape is this gasket has the passage cut out for the crossover that runs all the way across. Also located below the 2 secondary holes is a smaller hole between them that the similar gasket does not have. Many applications that use this style gasket may require 2 of these gaskets and use a metal gasket between them.  Generally you can reuse your metal gasket if you have one. If not we have the matching one listed as well. If your carburetor has an open gasket then this would not be correct and can be found in other listings.

 Following is a generic listing by vehicle. This is only a basic reference and please make sure your gasket looks like the one pictured above as some of the applications below may have came from the factory with a different gasket depending on build date, transmission choice, series and trim of truck, Canada only versions etc. Some of these vehicles may take a different gasket as there is some crossover between them. Some may appear as duplicated however they show up in the manufacturers data with different notes so we included them as shown.
