Sorry for the lack of updates. Been battling fuel leaks and setup issues. The OE filter/regulator has been replaced with a straight through SL55 AMG type filter, and the return line attached. Up front the new adjustable regulator has been plumbed in. Unfortunately, one of the -6AN fittings on the fuel rail got a nick in it, and proceeded to leak. Many attempts at cleaning up the nick slowed it down slightly, but any fuel leak is a no-go. A set of Koul Tools fitting fixer tools was ordered, and using the tool got the leak under control quickly and painlessly. In the process now of assembling the OE air filter boxes. Some interference on the driver's side with the return line from the front of the rail, but that will be addressed in a week or two. Using Car-Part.com, another M113K rail was purchased, and the plan is to use that, but also modify the fuel feed point to the center rear of the assembly, to eliminate the low pressure spot for #8 that is caused by the stock fuel feed location. FWIW, it would appear that the M112K should suffer from this same issue.

A very knowledgeable individual stepped up, and helped me with fuel pressure setup numbers. For reference, the really high numbers are not correct. 60psi at idle is the correct number.

Next will be the cooling fans. Currently, they are wired off of the original PWM type fan controller, but as has been noted by others, it does not run the fans fast enough. The car hasn't been driven yet, but it already wants to run fairly warm while sitting still. Based on that, one could guess that sitting in traffic in Florida summer heat with the A/C on is not going to go well. Likely, the fans will be wired to be full on for the time being, and an aftermarket controller wired in soon.
