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
A stock mechanical fuel pump should work fine. You probably have a rubber hose on a portion of fuel line. It would be a good idea to replace all rubber hose as it could crack due to age and then leak.
Only use stock hose spring clamps. Avoid gear clamps as these could cause your hose to crack in the future if over tightened.
Also, replace fuel filter.

No. The oil level is not that high. Not a difficult job. Can be tricky getting the lever compressed so you can gets the bolts in. Just takes some patience. You’ll see how it goes together when you remove the old one. Remove the two bolts and it comes right out. The gasket may hold on to it.
If the diaphram has developed a leak you could possibly be leaking gas into the crankcase. This will dilute your oil and create other forms of havoc. Pull your dipstick and take a whif. If your oil smells like gas better do an oil change as well when you replace the pump.

Update, went with an Edelbrock fuel pump and to my surprise had no issues getting it in and installed a few carb adjustments and she is running smooth again
That’s what I like about those all 60s technology mechanical fuel pump they wear out slowly to give you heads up there going down to give it time to replace Them.
Congrats
