Fuel Pressure/Vacuum on PT models

[sfedeli3]

Thanks a Bunch Jay!

I did pull a ton of rust out of the tank when I flushed it. I
guess some of those particles could be resting in the low points of
the fuel line or even jammed in there sideways forming a clot. I
disassembled the bowl and cleaned all components with brake kleen
last year hoping that would fix the problem. I even switched from 2
micron to 10 micron filters, but the vacuum was the same. I'll try
blowing out the line next time I'm at my garage.
