Dodge Caravan Stalls After Hard Accel

This 2001 Dodge Caravan 3.3L V6 (VIN 3 FlexFuel) came in
last week from another shop.
The guys at this other shop had just put a new fuel pump in
this thing about a week ago and couldn't get the problem to
go away. The symptom was that the vehicle would run fine as
long as you didn't go into passing gear. If you hit the
accelerator hard enough to get it in passing gear, it would
slowly stall and not restart until it rested a bit.
I put this thing on the rack, cause I didn't want to get
stuck on a test drive... but it wouldn't act up. So I
grabbed my cell phone, along with a bunch of tools and drove
out of the shop. On my way out the door, I told my boss to
get ready with the tow strap. :-)
Sure enough, the van quit less than a mile away from the
shop. The fuel pressure gauge showed 0 psi. But, while I was
waiting for the boss, I could hear the fuel pump running
when I turned the key to on. Also, using propane I could get
it to start back up. Obvious fuel supply problem.
We quickly got it back on the rack. I figured I would go
ahead and drop the tank and see if I could find a mistake in
the install of the fuel pump; maybe something in the tank
that would point to the problem. So, I unhooked the fuel
supply line at the tank and got soaked with fuel. No big
deal. Not the first time I've went home smelling like
gasoline. Obviously, I had more than 0 psi at that point in
the system.
Next, I hooked up 2 pressure gauges, one at the tank, the
other at the schrader valve underhood. I commanded the fuel
pump on with the scantool. I had 65 psi at the tank and 0
psi underhood.
I built a makeshift underhood fuel supply line out of pieces
from my fuel pressure gauge adapters, in order to replace
the suspect restricted line. I went for another test
drive... the vehicle ran great!
The O.E.M. replacement fuel supply line has no schrader
valve and no check valve.[2001 Dodge Grand Caravan Sport,
