I just received verification from a purchaser of a Purolator L2051 from Amazon that the size is 4-5/8 inches high and 4 inches in diameter. The Purolator P-51 was 4-3/4 inches high and 4 inches in diameter. With the use of the spring in the bottom of the Beehive Oil Filter canister, this filter should work great as the spring will push the filter up against the top after installed.
I think this is the one to go with, at least until Amazon discontinues offering it, which may be awhile.
