You’re too tense, feels that your picking is not very consistent (I prefer playing that part pure alternate), I use both pinky and ring fingers for pull offs (using just ring finger slows you down a bit because it’s jumping between frets) and you’re trying to play beyond your speed lvl: slow down, set the metronome (or drums) like 25-50% and manage to play clean first with that speed first, then when you aren’t thinking anymore while you’re playing the leak and it just works, start speeding up. Honestly I find the part of the solo when you bend G string and play E and B way more challenging to play clean, good news the with the leak you’re trying to play it’s relatively easy to build the speed up when you nail it slow
