Fuel Pump Compatability


Recommended Posts

Hi Everyone,

So recently had a fuel pump go out on my C4. Conveniently way far from home. Got a local shop to repair, and they put the fuel pump in from the C2. The car runs, but doesn't feel quite right. Does anyone know the difference between the two pumps, apart from the part number of course? Wondering how far to push this.

IRRC, the pumps are different because the tanks are different. They certainly have different part numbers. Even the return system is different. A shop should have known better. C2 is on the left, C4/C4S is on the right. #4 is the pump.
