Just got AD 150 installed. Now truck runs like crap. Can't hardly accelerate. Feels like it's running out of fuel. I left lift pump in tank and installed the draw straw. Truck pulls hard right up unto 2300 rpm then tries to die. Could filters be plugged already? I looked in directions and will pull it apart soon as I can find some replacement filters. I am totally bummed with this thing. I don't see how it could supply fuel to a heavily modified engine it can't even get enough fuel to my bone stock cummins. Wish I had just left it on the stock lift pump. Any suggestions before I put it back on the in tank lift pump? I checked connections and correct install and all looks good. Don't see any leaks on pump discharge side. Can't tell if suction side drawing any air how would I find that?

Please help ASAP!
