## Discrepancy

(CAN) O-RING IN HYDRAULIC FILTER BOWL BLEW OUT SIDE BETWEEN THE BOWL SEATS. THERE ARE 2 DIFFERENT TYPES SIZES OF O-RING FOR THIS SET UP AS THERE ARE 2 SLIGHTLY DIFFERENT BOWL TYPES. THE O-RINGS ARE THE SAME COLOR AND VERY CLOSE IN SIZE MAKING IT REAL EASY TO PUT THE LARGER O-RING ON THE SMALLER BOWL. THE SMALLER O-RING WILL WORK ON THE LARGER BOWL BUT NOT VISE VERSA. ONCE INSTALLED IT IS IMPOSSIBLE TO TELL WHICH O-RING IS THERE.  (TC NR 20060530003)
