Fuel pump question

[charger Downunder]

On my 440 six pack i am running a  standard 440 fuel pump that is used on a four barrel it has been on the car for over 30 years now will it make a difference if i switch over to the stock 440 six pump fuel pump. I picked up an Airtex 4845 fuel pump and pushrod just wondering if i should bother to do the change over before the old fuel pump dies.

I'd be more concerned about the age of your existing fuel pump than what model it is.  30 years is a long time for the rubber pump diaphragm to be soaking in gasoline   

Since you already have the pump and pushrod on hand, I'd definitely do the swap-out and consider it a pre-emptive strike... I'd rather do such work in my garage than on the shoulder of a road somewhere.  Done enough of that sort of thing already.

Carter 4845 is the best new choice.

I have original pumps on a bunch of cars and they are still spitting benzine.....maybe I'm just lucky.....hope I didn't curse myself!
