Maxiem Complete Pump Overhaul Kit

** Please note: This kit contains the new-style check valve assemblies F300-D0080-0000 (Omax #303401), which can only be used with the F300-D0052-0000/303294 liquid displacers. If you are upgrading your Omax 301641 check valve assemblies to the new F300-D0080-0000 (Omax# 303401) assemblies, you must upgrade to the F300-D0052-0000 (Omax# 303294) liquid displacers at the same time. Failure to do so will result in damage to your pump. **
