suburban tow truck fuel issue

[Tod Lane]

I built a 391 Ford for one of my dads box trucks years ago. He calls me about a week later telling me it would die intermittently. If you let it sit for a minute it would restart and run fine, until it died again.

Replaced the fuel filter, fuel pump, carb, replaced the fuel lines, even the distributor.

Finally dumped and cleaned the tank, about twenty little tin foil disk from the top of gas additive bottles came out. They would float around for awhile then get sucked over the intake hole.

Have you cleaned the tank throughly?
