Hello all,

I recently purchased an 2001 ML320 with 120k miles. I was having some issues with the fuel gauge and replaced my fuel pump thanks to the great DIY guides on here.

I am having an issue removing the fuel filter line from the engine. I was able to remove the high pressure and low pressure lines with the fuel line tool. is there something I am missing? I have attached a picture for reference.

Thanks,

AJ

 

Hi AJ - take a look at the link below; I hope that it'll help you troubleshoot ( I know the article say it's for a C class, but the process is the same for your ML).
