This has sort-of got me stumped. I got the air pump off, and want to also remove it's bracket. I'll just put some spacers on those studs and put the nuts back on.
But the check-valve is in the way.
I pulled and tugged and used a pry bar, but don't want to break anything.
How does that check valve come out, so I can get the bracket off?
Or is there another secret way that I haven't figured out?
then I'll put the valve back in and cap it off.
