Truck stalls when I select left tank

[JohnKimble]

Last week I replaced the three (3) short rubber fuel lines that go between the sending unit and the hard lines for the left tank of my truck.

Now once my truck is running, if I select the left tank, after about ~1 minute at idle, the truck dies. With the right tank, no issues at all.

I'm thinking I must have done something when replacing the lines from the sending unit to the hard lines. From what I remember, I reconnected them in the same order from the sending unit to the hard lines. The sending unit line near the front of the truck went to the first hard line near the front of the truck. Middle to middle, and rear on sending unit to rear hard line. I'm thinking maybe that wasn't the correct order?

Any suggestions?
