Low to Zero Pressure in Filter

[donpolo]

Hello - I recently had a problem with my pump not priming fully and had zero pressure in my filter. I was able to clear out some junk from the impeller, cleaned out all the baskets and my filter as well. After putting everything back together the pump runs fully primed but the filter is still almost at zero. I also got a new pressure gauge. I have good flow coming from the returns and everything "looks" good overall.

Should I be concerned about the low pressure?

Thanks in advance!
