Cpurvis- "burst pressure" being WIX makes them mainly for car engines, i seriously doubt peak oil pressure for these 1 or 2 cyl mower (vs 4-8cyl car motor is it originally for) is anywhere close to reachable.
Klinger- To find the one that fits my Kawi, i brought my used one to walmart and looked at the threds to find mine from Fram\Wix\etc. As I have said with another post- If it works with the flow rate of a car motor, it is fine with a briggs\Kawi\etc. AND it's alot cheaper....
