Hello folks once again, It seems I can never find what I need for the car. Now I have a engine light associated to the Evaporator fuel tank sensor stuck open. Problem is I cant find it to replace it. I have a 2010 E550. Thanks for any help

What is the code? I assume you're referring to pressure sensor part # 1635422818.

Thanks for your reply, I forgot to get the code but it said the Evaporator fuel tank sensor is stuck open. The part looks like this

I think I may have to drop the tank to get to it. I removed the rear seat and the two panels on top of the tank and didn't see it. Thought

Yes image posted matches part #. There are two fuel pressure sensors one on fuel filter and the one in discussion located on fuel tank see link to view tank: https://www.pacificmotors.com/auto-p...-w218-2010-11/

So is this on top of the tank where I can see it because none of the components look like the part or do I have to take the fuel filter out to see it?

Amended posts sorry for the confusion.

Thank you very much for your help!! So it does look like I will have to drop the tank somehow to access that sensor since there's no access panel for that area of the tank. I am surprised they would put the sensor there... bummer!!!

Can someone help me find out what’s causing these same codes in my 2010 c300. I have P0451 Evaporative emissions system pressure sensor/switch range/performance. And then P0497 Evaporative Emission System Low Purge Flow. I’ve been trying to figure them out for awhile. Any suggestions?
