Was doing a fuel filter change a moment ago. Everything seem to go smoothly until i started the engine and fuel started pouring out from the fuel tank!! Traced it to the top of the fuel tank and turns out that the fuel pumps's outlet nozzle had cracked. How in the world did that happen from changing the fuel filter? ...anyway do i have to change the complete fuel pump? Since the car is a mk1 16v Sporting, does that mean i can only use the punto 75, 85, and 90 fuel pumps?
