jean, just checked your manual and it does NOT look like an external fuel pump.Number 26 on the attached diagram is the "Fuel delivery unit" You might want to check closer at your filler lines as well as your vent and your pressure valves. Let me know if you need the manual, it is very large and might be hard to download if you are not on any kind of fast connection. Good Luck

You have two fuel pumps. The main pump is located where you described it. Take a closer look at part nr. 22 its a fuel filter made of aloy. Mine was totaly corrodet under the clamp holding it.

How I can remove the automatic gear plastic cover in side the car ? in order to replace the green pulp indicate light. ( Volkswagen 1993 )

Thanks in advance
