What part is this?

Yes, two universals. I have bad knees and this was easier than from underneath for me, YMMV

I too had to resort to using two univeral sockets! The real pain is loosening the hard fuel line! I can only move it like 1/2 a cm at a time!! geez.. Also I'm stuborn and refuse to remove any accessories or hoses unless necessary.
