Sounds like you had a hole in your diaphragm.

check your oil for fuel
if you got oil in your fuel pump
most likely your oil is diluted from fuel in your oil:(
check to be sure or just change it out...

I just checked the oil, still nice and thick on the dip stick with no fuel smell...think I’m good👍🏻

Question...Is there a reason the new fuel pump has a spring under the arm and the old one did not???

Yes, it is an assist spring, so that the pressure spring on the diaphragm inside the pump chamber doesn't have to also do the job of holding the arm up to the pushrod and the pushrod up to the cam lobe.
Prevents arm float from happening until a higher rpm..

It's a better built pump.
