An E-1G(Z) zinc will fit the Cummins QSD engine after cooler zinc's brass plug as both zincs have have 3/8"-16 UNC threads!! However, the E-1G must be cut with a hacksaw to a length of ¾" excluding the threads (the "B" measurement in the below photo), as the E-1G's "B" length is 1" excluding the threads. The E-1G zinc is 1/16" less in diameter, BUT I would much rather pay $2.10 plus versus $160+ for a replacement zinc. You might have to change the zinc more often, but what is $2.10 in the scheme of things?. Note: Just buy the Zinc Only, not the brass plug because it will NOT fit the QSD. Hack sawing will take only half a minute due to the softness of zinc. Be sure to return your unopened Cummins zinc back to Cummins with a big smile on your face...
