So how many of you have a E-420?

And does anyone know where the fuel sending unit is located? I'm assuming it is behind the back seat?

 

In the trunk, pull down the back panel against the back seat. There is the gas tank and youll see the fuel sending unit there, it has 1 plug on it. there is a special tool to remove it but you can use needle nose pliers or even channel locks. twist to the left 1/4 turn and pull out of the gas tank. good luck

 

Thank you for the tip! I'm hoping the float is just stuck...
The car sat for a few years. garaged

Judging by the comment of the special tool needed for removal, it must be have an o-ring seal? not a gasket?

 

yes its an O-ring, should come with a new sending unit. whats wrong with it? the float probably still moves, electrically they fail.

 

Its stuck on a quarter tank. I was hoping to clean it up a bit and see if it was just gummed up.

 

Ive been a wrench head for generations, First MB, love the vehicle but the PO was a rich brat who just bought a $100,000. BMW 4 years ago and the MB was just sitting around. 86K on odometer. $4,500. taker home.

 

Id say sounds like a great deal, if its been taken care of, but even if it wasnt, probably still worth it.

 

Before I bought it I called the dealer they bought and used for service they did at least bring it in for regular maintenance, until he got his new toy that is.

There are a couple of other issues to be repaired, there is a small oil leak on the front of the motor on the drivers side.

Should I be posting in this another area like the General Tech section?
