I thought there was a vacuum port somewhere on the manifold.  Oh well...

On Lou's point...I once had a fuel filter so clogged with rust that my old '55 Fairlane died in an intersection.  Maybe replace the filter and add one out of the tank?
Maybe a leak somewhere in the lines letting air in?  Something in the tank?

Id call tee bird products and talk with those guys they may have a kit for your pump

put a vacume tank for wippers
throw away the dual pump, stay with gas only fuel pump.have several low life cores, the strain on the pump linkage  helps a problem ,usly lack of gas. 

Although I have an FE pump and Newport electric wipers, if your OEM-style pump and wipers are working as they should, and you're not using your car as a daily driver, the OEM parts should last for years, not weeks or months. If you want to use OEM parts, it should be worth it to you to pay for quality rebuilt parts that weren't made off-shore. It is a common complaint for the wipers to slow down when the engine is under load, such as when accelerating, particularly when climbing.

Lou thinks we’re over thinking it. Google “think horse not zebra”.

Drive it. The filter doesn’t have to be full to move fuel through. Depending on the filter and the mounting, many may have an air bubble that doesn’t affect operation.

Mind boggling!

thanks everyone for your opinions  my gas tank is brand new so i will check the fuel line and pressure  test it   probably something simple  just a matter of testing everything   when i drove my 56 to town the first time it was on the road i had both hands on the wheel expecting something to fall off  or the engine to quit, i think i may be over thinking things

I can identify with that. I feel the same way first trip every spring. LOL
