Message: [QUOTE="weekendwarriorfsw32, post: 732747, member: 771"] Well I was hopiing that this pump would have done better then this but its not. Installed it with 190/75 injectors and at first it was perfect held pressure. 100 miles later the pressure dropped to around 50 from the set 60 and if you barley got on it would drop to say like 25 if I kept my foot in it. So I called airdog and they sent out a new pump, just the motor not the whole base. Went to start it up and its acting the same way, it's at 50 and if I get on it at all it drops. So I turned up the regultor on the pump till it was at 65 psi from 50 and went to drive it and same story, I get on it and it drops like a rock to around 35 and you can feel the power drain from it. So what else can I do? I know it was able to keep up with it at first so what happened? What else should I check? Drop the tank and look at the pick up tube if it's clogged? Filters on the pump? Any help is greatly appreciated. I am supose to drag race tomorrow at the Riffraff East event but need to get my fuel pressure back into check. This is a Airdog II 165. [/QUOTE]
