On the MK2 it’s is officially a fuel pressure regulator, so the connection is a vacuum which should connect to the inlet manifold and this automatically adjusts the fuel pressure according using the pressure in the manifold.

Maybe I'mm confused (not unusual) but I thought the 2000 MY Miatas had a single fuel line to the engine with the pressure regulator in the tank. I seem to remember working on a UK car that had that fuel system

Hi Snowbird, I think you are correct. Mine (US NB) has one fuel line from the tank and then a no/low-pressure evap return to the charcoal canister (the big one in the rear, not the fake one under the bonnet)
Hi Bit late to the party afraid, my car is a 1.8 98, and i have everything connected back up and it runs, I've retained all of the pipework as per Snowbird1s mantra of manufacturers paid a fortune to develop it so why remove it.
Ive moved the canister and the various relaysto the front corner next to the rad so most every connection is visible, do you want me to check anything?

Hi all, sorry for the delay, have been away, spoke to DanSt, I've removed the charcoal canister, no connection points due to going to TB's and suggests just a one way valve and catch can on both the regulator and the PCV
I have made good progress in getting the loom back in, have some life in the car finally, going to put some fuel in over the next few days and see if we have fire, well not fire but you know what I mean, that reminds me where did I put that extinguisher
