Can anyone help me out with fitting a fuel pressure gauge to my xr3i efi? Where do i put it? Does it go in fuel line to the fuel rail or doe it go between the fuel regulator and fuel rail?

 

As it is a bit difficult to fit it between rail and regulator as they are bolted together , the only sensible place is just before the fuel rail mount the gauge so it is not held by the pipework , either on the bulkhead or on the plenum and sort out the pipework to suit

 

As in the fuel feed to the rail?

 

Yes

 

Cool, cheers
