Hey thanks a lot everyone! So here’s where my dumb ass is at...
Upon replacing the fuel filter I also took the back off the fuel pump apart and looked for tarnish, which was good. It was replaced at some point. Something I learned is the odometer isn’t working. So I had originally thought the car sat for about 15 years, because the mileage was the same. So I’m not exactly sure now. (I got it at an estate auction) As I was blowing air through the fuel lines from the engine back to the filter, I soon realized I was on the wrong line. I didn’t know the pressure line comes all the way up to the front to the fuel rail. Doh! I was tested pressure on the return line. Lesson learned. I also bypassed to the solenoid going to the distributor. So now I have vacuum at idle. I took her for a bit of a longer drive today. After about 10 minutes the hesitation comes back. So much that even at a stop sign, the slightest amount of throttle she almost stalls. So back in the garage for now. I have tomorrow off, so I might go back in and check some items. I still need to clean off the crank pulley so I can set the ignition timing and maybe check dwell. I’ve never done that, I come front the new era where all you do is plug it in and read a data list.

So the things that are rolling around in my mind.

Is the fuel tank really that dirty, and after about 10 minutes the internal screen is getting too clogged? I going to keep driving her until the fuel level gets down to a reasonable level to change the screen. She’s still good to pick up take out and grab a six pack when needed. I should probably hook up my pressure gauge and monitor.

I’m also thinking about a vacuum leak after she warmed up. I’m going to spray some 2+2 around some vacuum lines, intake mainifold and such to see if the idle changes. I need to research this AAV valve a bit more.

I also found this vacuum valve, I’m thinking I could use this to replace the solenoid on the vacuum line going to the distributor. https://www.***************/pn/0015407097

I need to look into these trigger points as well. What exactly is their purpose? I’m guessing that there’s four of them, so maybe there sending to signal when to fire the injectors?

Thanks again for your time and knowledge!
