Yes - at the left rear forward of the rear axle under a black plastic cover.
16 gallons
Two pumps. Both are located under the car near the fuel tank. They are found under a removable cover. Hope this helps.
On the passenger side in front of the rear wheel. It is cover with a black cover. Remove it and there is the fuel filter along with the two fuel pumps.
Problem is most likely your alternator or your fuel pumps.
Most fuel pumps on post 1980's vehicles are found in the fuel tank.
The fuel pump on a 1993 Buick Regal is located inside the fuel tank. It pulls fuel from inside the tank and pumps it toward the vehicle's engine.
Why does my fuel pump keep running on my 1984 190E
It is controlled by a ECU but it is a CIS fuel injection system not a EFI system.
there are 2 fuel pumps on the car one at the tank and one in the engine compartment
it should be in the fuel tank wich is in the trunk behind rear seat. I have a 1993 190 and that is where the tank is on mine. Hope this helps. it will probably be covered with the carpeting.
There is no such thing as a 1998 190E, BTW - It was replaced by the C-class in 1993... On my Mercedes (1984) there is no cap lock, when you lock or unlock the doors, the gas latch (door) is locked or unlocked automatically.
A Mercedes 190e doesn't have a carburetor. They are fuel injected.
