PVC pipe (whatever diameter) 
2 PVC elbows (same diameter as pipe) 
1 PVC T (same diameter as pipe) 
1 PVC Cap (same diameter as pipe) 
PVC reducer bushing or coupling to connect PVC to pump

 This won't work Harvey, the whole thing has to be completely sealed and if you just have a pvc cap then you'll probably draw micro bubbles.  from the "t" you'll have to have a fitting that can be fitted to the smallest possible valve (ie r/o valve) or just have  a union like Richer's diagram.  If you glue a pvc cap on then you'll never be able to prime it again with ease.  Hope this makes sense.
