I modified Jebo 520 with beckett. I am using Rio 32 Hf on it. The problem is that, it only draws 8 lpm of air. Is it normal? I found a deal on resun MD 40 pressure pump (I think it is the same pump as Gen-X PCX30). Should I buy it? I've heard that, even rio 32 hf is more powerful (1920 gph at 1 feet) 825 gph pressure rated resun performs better. What should I do? Thanks.
