Possibly, but what I don't get is WHY the (less than 6 y.o, and less than 4k miles) Bosch FPR diaphragm would rupture when a new Hella fuel pump was installed. Coincidence? And why did the fuel rail lose pressure, that last "work day"?

I'm sure I'm mis-thinking this, and I miss the old days when I could install, plumb, and wire a new tank, braided fuel lines, fuel pump, filter, pressure regulator, pressure gauge, carburetor, and fine tune it all in one afternoon. That was a long time ago, in a Galaxy far away....
