Well I was using a flat head screwdriver as a punch because I didn’t have a long enough punch. I suppose the air hammer could work, but I assume that it’ll just cut through the filter head like the screwdriver did.
I went and ordered one of these things: https://www.aircraftspruce.ca/catalog/topages/talonoilfilter.php?gclid=Cj0KCQiAy579BRCPARIsAB6QoIawYVlxymFajP4AKoceU7B1hP13lrzJE5tEDoDOlWA5JQYNxHZtppYaAibhEALw_wcB
It’s pretty expensive and will take a while to ship, but it’s less expensive than learning how to weld lol. Plus I don’t like the idea of welding right by all that oil and diesel, especially when I don’t know what I’m doing.
