64 Valiant Fuel Problems, PLEASE HELP

Agree with RRR, cheap first blast from the shot gun.

To locate the problem do some testing.

There are 15 places that could be a cause of no fuel to the carb.
  1. Fuel tank vent
  2. Fuel pickup sock
  3. Fuel pickup tube
  4. Hose from fuel pickup to hard lines
  5. Hard line clogged
  6. Hard line to fuel pump hose
  7. Fuel pump
  8. Fuel pump eccentric
  9. Hard line to fuel filter
  10. Hose from hard line to filter
  11. Filter
  12. Hose from filter to carb
  13. Hard line from filter to carb
  14. Carb float
  15. Idle circuit in carb.
If there was a leak of blockage at any of those locations that could case your problem.

The nice thing is you can test at just about every point.

But start at the carb and work back.
