Rather than spend $115 on a filter set and $60 on the orings (which is crazy!) I am going to buy a complete pump assembly and have a back up pump to carry.
Fair enough, I can understand that.
When my filters failed they were similar - brown, but otherwise not obviously clogged. I wouldn't have believed that was the problem if I hadn't blown the filter out with gasoline and compressed air and had it temporarily fix it.
You can re-use the o-rings. Mine have been in and out a half dozen times and are still sealing fine. They are pretty hacked, but that is mostly because I am a ham-fisted wrench.
Next time I have the pump out, I'll put in normal Viton o-rings instead of magic $60 KTM o-rings. If anyone has source and part number or dimensions for replacements, chime in. I know others here have done this.
