I'll be buying an msd chip for my saff soon and was just wondering how people are testing fuel pressure on the 4wd cars with the reg direct on the rail

Mine is bolted directly onto the fuel rail As it's a 4x4. So there Is no hose between the rail and the regulator. Mine also still has the factory tamper seal fitted so is it still likely it will need adjusting

The regulator holds pressure in the line before it so if it's set to 3.5 bar idle, then you will see 3.5 bar whether you check it at the rail or directly after the fuel pump, after the regulator will just be what the regulator is bypassing so is irrelevant.
You have to measure the pressure somewhere before the regulator.
