Nobody is holding gun to your head. Those of us who have done this mod are happy with it. If you're uncomfortable with it, it's as easy as just not doing it.

I'm all in favor of improvements toward reliability. I've done it myself on a lot of the systems. As I said in an earlier post, time is the ultimate test as per reliability.
While we're at it though, I think the BS about "pulsing" fuel by the old pumps is an old ploy by sales folks to get you to by something. In this case something that does not fit.
I've taken two failed pumps apart. The failures have to do with "sucking air". The contacts fry very easily if a pump is run in open air at any time. Also there is absolutely no mechanism of "pulsing" the fuel in the our system. The primary pump is on all the time. The fuel system is a closed loop that returns unused fuel back to the tank. Now on my Explorer it's different. The pump is the same type as the vett but the electronics do in fact "pulse" the fuel and there is a device inline that absorbs the pressure pulses. Our ZR-1s have a regulator that drops the pressure to the rail if too high. Whole different concept than the systems (like the explorer) that regulate by turning on and off (pulsing). Even the name of the device is different on the pulsing systems. They're not called "fuel regulators". (can't think of the name right now)
Again the need to use a "turbine" fuel pump aside, I honestly hope your mod holds up. I'd declare it a success if in two years there is no cracking. But then you'd have to take it out and look either by a pump failure or just to "look see".
