Johnfog,

What brand and number filter is the parts guy recommending?

There is one-size of 58-63 261 full-flow canister filter cartridge (I think that 1143 is the NAPA number). I doubt if that filter would fit in any of the 1qt or 2qt by-pass canisters that I have seen. It is taller than any 1qt canister filter that I have seen and shorter than any 2qt filter that I have seen.

Do you have the old filter cartridge to bring to the parts guy (he might have dimensions in his catalog)?
