[DeTomaso] 73 pantera Vapor Lock?

[John Taphorn]

I read your post twice; yet, can't exactly visualize your fuel line routing. 
That said, I suspect that the problem is not vapor lock; rather, I suspect 
that your filter is becoming clogged and limiting fuel flow.  The old fuel 
filter harboring a significant amount of sediment suggests that you may need 
to flush your fuel tank.
