REMOVE FUIL TANK - 1995 Mercedes-Benz C-Class

yes
but to be successful you will need an inline fuse close to the battery terminal, the power line to go through the pressure regulator switch and then through a separate switch on the dash so that you can switch it off when you leave the car
better just to fix what is broken

upon researching this make & model of car it seem that the fuel filter is located in the fuel tank on the fuel pump & should not need replacing unless your tank is dirty.

The pump is inside the gas tank, so the tank has to be drained and removed from the van.

Very possible. The code for the fuel cap is probably one of the codes for a pressure leak in the gas tank vent system.
If it was not smelling before the brake repair, I would take it back to the shop that did the work.

You need to remove the fuel tank from the vehicle. then remove the fuel pump from the top of the fuel tank.

remove fuel tank 2 to 3 hours labor

does the car start and idle?

If so, replace the fuel filter - being you put in a new pump, then filled the tank, driving to the station may have caused seditments to get into the filter and plug it up.

Also, find your MAS (mass airflow sensor) and with car running, tap on it with a screwdriver handle (or small tool) -- if the car dies, or stalls, (idle fluctuates; more so than while just idling); you can first purchase MAS spray cleaner - remove, spray inside (honeycome) generously, let air dry for 15 or 20 minutes; install and start engine - tap again with small tool, and if it still dies, stalls, or fluctuates, replace the sensor (MAS).

Also, make sure that if you already installed a new fuel filter, that it is facing in the right direction. On most (inline {near tank} filters}, there is an arrow that should point toward the front of the car (or if mounted horizontally (from one side of car to other, facing both directions) make sure the arrow is facing the driver side.

Please let me know if you need further assistance.

It is inside your fuel tank, you will need to lower or drop your fuel tank to temove your fuel pump.

first check the switch on the dash. check for power, red/yellow wire should be battery power. brown/white wire is rear tank, red wire is front tank

did it run when it was parked?
and fuel pumps will go bad sitting for that long!!!!
