Took the bird out for a spin last night and noticed she was hesitating and sputtering a little while stopping. When I did park there was the smell of gas, so checked out the lines, filter and carb. All seem to be in good shape which now leads me to believe the fuel pump is starting to die, was able to get her home and was wondering if anyone has any recommendations for either the Edelbrock mechanical fuel pump or Holley, or stock style from an auto part store. I do want to stick to the mechanical style on the motor, so any tips or tricks would also be great as I have yet to replace a mechanical fuel pump. The motor is a 72 400 with an Edelbrock 600 carb. Thanks in advance for any info it is greatly appreciated
