I have a Seicento SX 1.1 02 and it has a fuel tank leak. I have found a fuel tank from a seicento sporting for £40. Will it fit?

not 100%, but 99% sure you will be fine

The tank itself will fit 100%, what you may want to make sure that the fuel pump has the same mounting, cause this is usually where this goes wrong. /Woj

Please advice (after you mount the tank) if it was ok.

The fuel pump should be the same, it's still a 1.1 whether it's a sporting or SX.

Yes, but for example Cinq 1.1 and Sei 1.1 SPI have the same engines, but tanks (pumps) are different - that's how I got a wrong tank for my cinq - visually very similar, but the pump just would not fit... /Woj

Also MPI fuelling system is different to an SPI based on posts by mintysport.

Hi ive been hunting high and low for a seicento sporting fuel tank where did you get yours from

Go to your friendly Fiat dealer and see if you're covered by the latest, greatest, recall.

Scrapyard, ebay, etc
