GL350 OM642 Fuel Filter to High Pressure Pump Hose Question
Hello Everyone,
The car in question is a 2015 GL350 with approximately 175,000 kms on the odomoter. The MB recall has been done on the car as well.
I have no idea how but somehow I developed a puncture in the hose going from the fuel filter to the high pressure fuel pump. I thought it would be a pretty straighforward job but I've run into a sall issue. According to my VIN, this is the hose that I need. Yet the hose that I pulled off the car is like this one (without the sensor).
I assuming I should just go with the sensorless hose since that was what was on the car. Even if I did get the one with the sensor I wouldn't have anything to plug into it. Maybe the recall is when the hoses were swapped out?
Next question is this, will the above sensorless hose the fit? I assume there isn't much of a difference between the X164 and X166 (other than the sensor it seems) in terms of routing so the length and kinks should match up right?
Oh, I also snapped the *****ty plastic T on the return line so I'll be ordering the entire harness as well to resolve that problem.
TIA!

Nevermind. Id10t issue. My hose does indeed have the sensor, it's just that I removed the paet of the hose before the sensor and left the rest attached onto the car.
