May 31, 200719 yr comment_179685 I do know (from an error I made about fifteen years ago) that there are two different sizes, and if you use the wrong one, the sump doesn't fit. What I can't tell you is whether the difference is 3K to 4K, early 3K to late 3K, or some other combination there of. Report
