Hello,

First of all, there are three injection systems on the Seicento:

But apparently two pumps:

The part number for the mpi version is 51709818.

The same pump was used in other FIAT models:

I went through the firsts search results on the internet but couldn't find the pressure. I think that having the part number it would be easier for you to find it.

The above information are taken from the forum ePER, the FIAT spare parts catalogue. The link is on the bottom of the forum banner, you can browse by models and categories, or search by VIN or part number.
