I have installed a brand new SX pump and it's making a very weird noise (like bubbles in the line or difficulties pulling). I have a filter right before the pump. and a -10 line about 12" long to a sump tank. Anyone sees what's wrong here? The pump was replaced thinking it was defective but the new still doeas the same thing. I also flow tested the pump with a bucket of gas and flows fine without making the loud noise. Any ideas?

Thanks,

Angel

If you're talking about a fuel pump, it's supposed to whirr a little when it's in use. That because of the FPR imposing a restriction and forcing the pump to build pressure. If it's gurgling, that means it's sucking air, and getting bubbles in the lines; make sure it's mounted properly.
