Not sure if I'm posting this right. I have a kubota l2800. It's a hst. I was bushhoging a few weeks ago and thought I hit a stump on my hst filter because it's was leaking lol. I got new filter from dealer and it is leaking in same way. It's like it's pushing the seal out of the filter. So I bought a new filter mount and put it on. It ran fine for about 20 minutes and the seal blew out again. I've searched the web for a similar problem but can't find anything. Would love some info if anyone can help. Thanks
