Customer Question
I have a 2005...

I have a 2005 cl55 amg. the fuel pump makes a noise from too much pressure. I am told it is caused by a faulty "check valve" inside the gas tank. that would be fine but an inventory search of north America and Germany revealed that there are no tanks available. I refuse to believe my car is not a paper weight, it is immaculate 52000 miles otherwise. there must be another answer. Im just looking for a direction to head. thanks

Mechanic's Assistant: Have you ever replaced the fuel pump, or is this the original?

Brand new oem, yes

Mechanic's Assistant: What is the model of your '05 Mercedes?

Cl55 amg

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

Been to three shops including the MB dealership everyone throws there hands up

Hello my name is ***** ***** welcome to just answers! I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required. If I don’t answer right away or quickly in conversation I am helping another customer or have stepped out for a moment and will respond as soon as I can. Ok lets get started!

So the regulator is in the fuel filter actually, im surprised the dealer is being weird about it, so the car was tested and the fuel pressure was too high?

They weren’t really being weird about it we put for fuel filters in it knowing that it is partly responsible for pressures it’s actually the check valve in the fuel tank that is the culprit and apparently you can’t replace the check valve without replacing the entire gas tank very frustrating
