Yes I do. Just run the pump by turning the ignition on and it should show the regulated pressure on a gauge at the test point and hold pressure for a few minutes. It will dissipate over an hour or so. If you have a super "Emil style" fuel system I am told the pressure drops off almost immediately the pump stops but the standard Mahle type filter/regulator should hold pressure for some time.
Sounds like Emils system is a more safe system. Who needs fuel pressure after and emergency shutdown from a fire!?!

I don't think it is a safety issue but just the way the pressure regulator works. I am sure the regulator in Emils system regulates the pressure more accurately than the Mahle filter /regulator but the Mahle one has to comply with it's OEM specification that says it has to hold pressure after supply stops for a time, probably because most engines fire up quicker than the X-wedge if they stall. I imagine it is easier to regulate a constant leak rate than to hold a pressure when the supply is gone, particularly for a combined filter and regulator that is a throw away item built to a price of about £40. Agreed that in our installation there is no need for the system to hold pressure for any length of time but most of these filter/regulators do just that.

Anyone know what the correct spark plug gap is for the M3W I just changed my champion RA8HC plugs. One was set at 28 and the other at 30.
I put in NGK DCPR7EIX and out of the box they are 28. I put them in as out of the box 28.
I dont see any difference between the two. Seems to start the same and took it for a short
drive. All seems normal. My old plugs only had 3300miles but I read on a face book users page
that the NGK plugs help with starting. My old plugs still look good so will keep them as spares.

I think with the big fat spark of modern electronic ignition systems, spark plug gaps are far less critical than they used to be. Obviously for Raphy and me running our S&S engines in a hot climate, where cylinder head temperatures get quite high, especially if using the original baffled exhaust system (my cylinder head temperatures dropped over 40ºC by changing to G56 non-baffled exhausts), resistance to thermal erosion is an important consideration on the plugs and that is why I use Iridium plugs. I would think Bosch platinum plugs, like Porsche recommend for their turbo engines, would be equally good.
