02 audi a4 quartto fuel pump or fuel transfer pump
2002 audi a4 quarto. Blue 60K Gas gage reads 1/4 tank, replaced right and left fuel sending units. Noticed right side of tank is full and left side of tank is 1/4 full. So this shows me the transfer pump is sucking fuel from the left side to the right side where the fuel pump is. So do I replace the fuel transfer pump also known as a sucking jet pump that is just a plastic valve with hoses, no electrical on it, or the fuel pump that seems to be working fine as the car runs great. anybody have any experience on this type of dual fuel tank system. Thank You
