There are essentially 3 failure modes observed with this pump assembly:
1)Loss of flow during normal operation after extended highway cruising
2)Loss of flow during relatively high-G left-hand turns
3)Loss of flow during normal operation after 60k miles or more

Thanks.

came across this doing research for the future FI project, it should address everything discussed here:

Good info.
Look at that: The Walbro puts out nearly as much fuel as the coveted "Supra" pump in a package that is half the size and using half the current.

You should see at least 60 PSI in the rail with a stock pump (anything under that fails the siphon function). I think the highest I've seen with the modded pump is 71 PSI.
The only "blown off hose" involved with this is the pressure relief on the siphon assembly and that is addressed in the instructions in this thread.
