Having fuel problems. losing RPM and stalling. I will need to replace filters for sure. My inquiry is when it comes to the fuel pump. 2017 BX25D has two fuel filters, one near the tank and one just before injector pump, the fuel pump is just after the fuel tank filter. While this was factory installed it has never been plugged in because there is no plug on the wiring harness to plug into. Is this common? Strange that they put the pump in but power supply. This is the first fuel trouble since new in 2017.
