[Chrysler300] Hurst running poorly - UPDATE

[stephen schieser <sjschry70@xxxxxxxxx>]

Thanks to everyone who responded to my e-mail about my 300 Hurst - many very good ideas and suggestions! After reading all of your notes, I looked down the carb and the accelerator pump was not squirting much gas when you opened the throttle. I disconnected the fuel line at the carb, ran a fuel line from there into a glass jar. I cranked the engine with the ignition off, and there was not much flow of gas into the jar. I disconnected the fuel line at the gas tank to confirm gas was getting to the fuel line from the tank ( my gas gauge quit working a number of years ago and I have not repaired it yet.) I connected a piece of fuel line to the fuel line just forward of the tank and ran this to a jar of fresh gas. I then pulled off the fuel line from the fuel pump to the fuel filter ( just below the alternator ). A lot of rusty, grainy, dirty gas drained out of this short fuel line. There must be a lot of rust in the long fuel line from the tank to the engine, or rust in the gas tank?
 With the ignition off, I cranked the engine, to see if the fuel pump would pull gas from the jar of fresh gas back near the tank, through the pump and then into a glass jar at the discharge of the fuel pump. I got very little fuel flow. I then hooked a fuel line from the jar of fresh gas to the suction side of the pump ( to bypass the long under car fuel line ). Cranked the engine again and got no fuel flow. I hooked a vacuum gauge to the suction side of the fuel pump and cranked the engine - got no vacuum reading. I suspect the fuel filter is plugged up and the new fuel pump I put on 2 years ago is not pumping? Maybe the rust and dirt in the line ruined the new fuel pump? Should you get a vacuum reading at the suction side of the fuel pump when you crank the engine? I would think so?
 
Tomorrow I may try to gravity feed the carb and see how the car runs. I likely also will pull off the fuel pump and see if there is anything wrong with it? I will also replace the fuel filter above the fuel pump, once I get the fuel pump to pump some gas. Any suggestions or ideas based on the above note will be greatly appreciated!
