ive been chasing fuel pressure drops for months now with aero motive pumps. ive tried 5 different 340lph, a smaller 200lph, different inlet styles, improved wiring, heat wrapped all lines in the engine bay, but every single aero motive pump ive had has eventually started to become noisy and drop pressure under WOT. im talking from 43 psi to the mid teens. threw in a cheap 255 and problems immediately went away. pressure held steady as a rock versus the aeromotive pumps that even out of the box would be dropping 2-3 psi under no load just revving it in my driveway. are these things just junk? an aero motive rep and I tackled this issue for several weeks and even he couldn't figure out what was going on. wiring checked out, voltage was good, flow tests when the pumps were new came out fine, feed and return are sized fine for my power level (around 450 crank, running -6 an the entire way), tried two different regulators (Holley and aero motive), but after a couple weeks these pumps just can't hold pressure to save their lives. some came completely junk out of the box and I had to send them straight back. just gonna switch to walbro and hope that solves my issues permanently but I just find it really odd how a no name 255 pump almost seems to vastly out perform these pumps (no loss of fuel pressure whatsoever under wot conditions). Anyone else have this issue with the 340 series pumps?
