Halfway between your battery and the break fluid container. Between the engine and the dashboard there is a double firewall - relays sit right there. The fuel pump relay is speck in the middle between the driver and passenger side. It is a good matchbox-size plug-in. Don't confuse with the other relay "Klima" (a/c relay) that is directly towards the driver-side. The fuel pump relay, if original, bears "Schaltgerat fur Kraftstoffpumpe 12V" marking and a number (mine is 89 8182 000).
