*STUCK* Replacing Fuel Filter Housing

Hey everybody, this is my first post, I literally just figured out how to make a post🤦🏽‍♂️But I’m replacing a fuel filter housing on a W212 Om651, and I’m stuck on this “Y bracket”. I’ve gotten the right bolt out but can not comprehend how I would gain access to the left bolt. Any help would be greatly appreciated. *in the middle photo you can see from the other angle that I probably could disconnect the fuel rail sensor and gain acces, but I don’t want to fu** with it if I don’t have to as when I went to disconnect the sensor, it pulled the plastic piece of the fuel pressure sensor with it, I don’t think I quite broke it yet but I’m not trying to do so* Happy New Year Everybody

Well that connector should disconnect pretty easy which would give you some decent access. If you absolutely dont want to disconnect that then maybe a 1/4" short extention with a universal elbow and short socket may work. Would have to look at mine to be sure.

FYI there is a diesel section but also putting om651 in title may attract more knowleadge people in the area.

Did you disconnect that sensor? Never heard back from the OP and curious why anyone wouldnt do that to gain access to that bolt.

yes I did, though the wiring is tight and very difficult to get to last bolt, is there a way to release wiring loom to make things easier?
