If you are replacing your fuel tank, you really need to replace your Mk2 Scirocco Surge Tanks. As you can see in the photos, this vehicle’s tank was extremely fuel soaked and almost to the point of failure. They should not be brown. This was because this fuel tank had very heavy corrosion in it. Furthermore, the fuel had been sitting in the tank for over 10 years and had never been maintained with fuel additives for long term storage. As a result, we had to replace almost everything on the fuel and EVAP system. So if you are replacing your fuel tank, you really need to replace this at the same time.
NOTE: On the Volkswagen ETKA part diagram the tank – part No. 533 201 511 – is also known as a “fuel filter”. “fuel expansion tank”, and/or “fuel compensation tank”.
Purpose of the a Surge Tank
These surge tanks do a couple of things. Firstly, the internal fuel pump, transfers fuel into this tank. then sends fuel to the external hi pressure fuel pump. Next the fuel pumped to the fuel distributor. Any excess fuel pressure that is left over returns to the surge tank. As a result, your engine will never run dry. The constant flow of fuel feeds the external fuel pump. This helps in heavy cornering situations and will never allow air to enter the fuel system. Any unused fuel not used by the external fuel pump will exit the Surge Tank. This will exit via the overflow port. This port returns the fuel to the main tank for a continuous closed loop system. This tank will also acts as a filter, if there are any large particulars present.
