Technical Fuel pressure regulator?

[AndyRKett]

I want to get my little Mk1 running its best, does anyone know the pressure rating of the fuel pressure regulator, I noticed the little screen/filter on mine was broken so seems sensible to get a new one?

I am going to also change the O2 sensor as well which I presume is just a standard 4 wire narrow band? I do need to sort out the exhaust as while I have fixed a leak at the manifold the manifold to down pipe joint had cracked and is now leaking a lot of exhaust gases which will not help the O2 sensor know what is going on.

Sorry I have forgotten what spec. yours is. If you look at the bottom of the page on left it appears they are all 3.5 Bar.

That’s perfect thank you, I’ll get one ordered as they’re only about £8 and a O2 sensor at the same time.

which engine? SPI models (55 and 60) have a low fuel pressure of around 1 bar, MPI models (75, 85 and 90) have a more standard pressure of cca 3 bars. The regulators are not the same

As per the Book picture posted above it would be 3.5bar.

Its the 1.2 Mpi 16V 86 hp engine in a Punto Cabrio shared with the Punto Sporting.
