Fancy prairie, Illinois | Working on a 3116 in a Chevy topkick. The truck is hard starting and low on power. The filter on the suction side is only half full. Pressure side is full. With a clear hose on suction and return the suction side has bubbles present at mid to high throttle. Bubbles are maybe 1/16" 1-2 inches apart. Return side has thousands of tiny bubbles at low to mid throttle, clears at high throttle. What's everyone's thoughts? Bad injector cup? Plastic supply lines have been replaced, suction filter was vacuum tested. Cracked pickup tube in tank?
