After buying 1/2" PVC pipes and fittings from the big box hardware store, I saw that the local store carried 1/2" CPVC - which looks like it will work better for this application - 1/2" ID/ 3/4" OD slides snuggly into the CPVC fittings and slides over the pump's outlet nozzle with just a little work. CPVC has the added benefit of having a significantly smaller outer diameter than PVC, making it easier to hide in your gravel.
Just wanted to share that with anyone else who might be taking on this project.
