Accumulator/ Filter: 88-92 Corvette (3 outlets)This is the correct 88 92 Corvette Accumulator or Filter Dryer as it is often also known with 3 inlets oulets (not 4) If your changing your compressor.. or changing gas.. change this also.. You would not change engine oil and reuse the old oil filter .. so don't waste your time changing compressors without changing Filter Dryers.. no matter where you buy the right parts from.. IF you will need to change the full gas system from old style gas to new
