Yeah man true to the recording you want to hammer on/pull off the middle part of the verse riff.
When I used to play this I would play each note of the triplet at the end...much the same as the triplet on the verse of "Roadhouse Blues" by The Doors.
There's a few versions on YouTube including some tabbed instructionals. Some guys are hammering on, some are playing them straight. Check em out and see what works for you.
Once you get the tempo up you will probably find it bury in the mix a bit anyway, making it harder for the listener to tell whats going on
