Sorry to hear of your trouble. Did you contact Swiftech to let them know?
I'm not aware of any other pump that comes with those pushlock fittings. Swiftech uses
John Guest Speedfit fittings which are available in NPT and BSP pipe threads. Once you know what type threads are in the replacement pump (and if they are available), you could order the correct fittings for it and screw them in.
Another manufacturer by the name of Watts makes similar pushlock fittings for 1/2" OD hose though I don't know what thread types they offer. The PL-3035 I picked up has is 3/8" male NPT. The ID of the male threads matches the 3/8" ID of the hose. They are white instead of grey and have a larger flange so you can release them with your fingers instead of using that plastic tool. I picked one up at Home Depot to use on my reservoir as I have one system I wanted to retain the push lock fittings on.
Or you could simply use barb fittings in the pump and push the hose over it. By heating the 3/8" ID hose, you can get it over a 1/2" barb fitting.
