Correct fuel pump pressure on a '30

[CarNucopia]

Does anyone have a sense of what the correct amount of pressure is from the original fuel pump on an 1930 60 series? I seem to have misplaced my reprint of the Specifications and Adjustments Manual.

Thanks,

If it has the original Marvel set up, 3-5 psi is all you need or want.

Thanks Mark. I'm having a problem where the car stumbles after a few minutes at a contestant speed, like 40MPH. I'm hoping it's the fuel pump because I suspect that's an easier fix then the dealing with the Marvel.

With the engine warmed up and at idle, adjust the big knob on the Marvel a half turn in to a richer mixture and see what happens at speed.

Thanks for the advice Mark. It'll be a few days before I can get the car out and play, but I'll let you know if that works. It would be great to have a simple solution.

Thanks again Mark. Fortunately, the issue was the fuel line, so I didn't need to touch the carb.
