Repairing crack on pressure washer pump

Hello, first post here, wondering if anyone has had success repairing a crack on a pressure washer pump. It’s a CleanForce 1800 PSI electric, had it for many years, and has been a pretty good unit for me. Can’t get parts for it, so thought I’d try a repair while I decide on a replacement.
Crack is along a small section along the seam (picture):

I thought maybe some JB weld, but hoping for some input from someone who’s maybe tried this. I realize this is quite probably never going to be a real fix, but would like to give it a try none the less.
Thanks!

JB Weld is only good enough to get you to a proper fix right away. It’s pretty worthless stuff.

A 1700 PSI electric pressure washer can be found for under $100. Just buy another one and save yourself a ton of headache and time.
