Fuel/Water separator

I was having fuel issues - engine dying occasionally at above 5000rpm, but not cutting out. I had a feeling it might be the fuel/water separator so I replaced it this evening. I primed with the bulb it until petrol came out the bulb and I connected it up. I started the engine and it ran fine at idle but I did not want to rev it to 5000rpm on the hose. The separator will not fill up fully, am I am wondering is this normal? Or do I have another issue?

The separator should fill completely. Since it doesn't, my best guess is the fuel pump is bad or there's a massive clog in the internal fuel filter.

When you're running at 5k get someone to do the primer bulb. If it picks up then I would say pump at fault

Unless you are sucking air, I wouldn't worry about a little bit of air in the fuel filter. It won't hurt anything, and if it winds up getting into the fuel pump it should easily pass. In your photo I can't see any air??
