Should the fuel pressure regulator not bolt onto that end of the fuel rail? to supply the return hose connector
For the hose adaptor i'd look in the yellow pages for pnumatics supplier (or however its spelt)

It should deffinitely have the regulator there otherwise you will get no pressure to the injectors

There isnt a fuel return on the st170, it has some clever pump that turns off and on to maintain the pressure. The pressure sensor I believe bolts
onto the end of the st170 fuel rail, the hole in the picture. This setup is no use as I need a return to the tank from the rail. So a nozzle is
attached then this allows fuel hose to be attached to the end of the rail. You can then have a seperate reg from the rail and finally the return to
swirl pot.
Cheers

The bit that bolts onto the fuel rail on the standard Zetec is the pressure regulator which in turn has an outlet for the return if you don't
have this then there will be no pressure in the fuel rail and your engine will just about tick over at best as there will be no pressure at the
injectors.
Are you sure that the pressure sensor that you refer to doesn't have a return? If not just get a standard zetec regulator as that will give you
the return and the regulator.
My archive has a photo of my dressed manifold with the regulator on the left end (pictures not brilliant)

Keith, Steve is correct in the way it works. The latest generation of cars have a returnless system with a modulating fuel pump to maintain the
correct pressure in the rail. It's been developed to reduce cost and emmissions .
Steve, I have modified a ST170 fuel rail in a similar way to the pictures you have shown. I used an airline fitting with an 8mm push on tail. Have a
look at the Machine Mart catalogue for inspiration

Now finished! Xflow-Zetec swap with GSXR TB's and Megasquirt.

In alloy or steel??
Either way, just turn one up from bar.
If you don't have the facility, someone on here will spin one up for you.
If there's nobody local I can make one up for you.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

In the end I used a Ford probe regulator on the end of the fuel rail. It doesnt fit as standard. The reg is a tiny bit biggar. I filed it down and
drilled new fixing holes and it works a treat. I used the O ring from the removed pressure sensor. There is no hint of a leak but I will keep a very
close eye on it initially.
