can someone help to find right replacement fuel pump of my nissan march(micra) k11, some one knows the rating of how much does the fuel pump flow letre per hour(lph)... i cannot find orig nissan micra k11 fuel pump, since this car isold enough and hard to their parts. i bought exact design fuel pump from nissan sentra 1995 the pump has only 1 backflow of its pump compare to the stock fuel pump whis has 2 hole or back flow. please refer to the attached image. the problem of my nissan micra(march) is, i already put a universal pump, the problem is i can feel the engine is running in rich fuel and cant burn all the fuel, because i think the fuel pump is universal and not design for nissan micra and with high flow rate.so if its run in high rpm the engine is okay, but when i met in traffic, the engine stop.
