I'm pretty sure that mine is a
2-274, so it's actually 9.875 long rather than 9.5 long.
Close enough for useful comparison though IMO. Same number of flat tubes.
Bill,
Is connecting directly to the 5/8" tubing of the core a problem for you? I wasn't planning on putting barbs on, but I can if it makes things easier and/or it makes the comparison of the two cores more relevant. I wouldn't want to go smaller than 5/8" barbs though.
BE,
The 2-342 has a 3/4" and a 5/8" connection.
Were you planning on adding barbs?
