New fuel pump won’t idle

That’s what I was thinking too. I’m new to mopar cars. Grew up on gm but got this duster of my wife’s grandpas. Car is here and grandpa is gone so trying to get it dependable again. Thanks again

"IF" you end up removing the pump, just check to make sure the last bit of the arms on each is the same. It's probably the right one.
