We've gone through our used regulators and most are bad at this stage.

We used the Mercedes version with good success although a 90 fitting was needed to keep the return hose away from the exhaust manifold. Sadly, it's now NLA.

The 280Z regulator is a close match but it's vacuum referenced and non adjustable. With the vacuum connected it runs ~28 psi, disconnected it's 36. Because of the ethanol in today's fuel a little more pressure isn't a bad thing but I haven't tested one to see how well it works and whether or not a vacuum signal is necessary.

We do have a couple of NOS regulators as well. My brother has PM'd the OP.
