I could be off on some if this but there should not be any significant difference between the 76 and 77.
Could be true. Why not just use a newer WUR and plumb in a boost line instead? There may also be differences with the internal resistance of the heating element, whereby it heats up quicker (or slower) than say an 80's version...affecting the cold enrichment time frame a bit. Not a big deal, though.

If you suspect yours is going south on you, try contacting Brian Leask about rebuilding it.

Or contact these guys Porsche Parts-Special T,Porsche CIS fuel injection parts, fuel distributors, warm up regulators- for a possible new one.
