How Can I Fix an Electric Fuel Pump with 5 Pins to a Fuel Tank That Has a 4 Pin Socket Connector?

apparently - you got the wrong part for the right tank - which means you got a 'special model' where a substitution was made may need to dig deeper - see if you can take the part back - Auto Zone, NAPA, or Advance should know about the problem last resort - take it to the dealer = they had BETTER know! best of luck!

2. o1 Dodge ram 3500 5.9 cummings, pickup pump went out, can a inline electric fuel pump be installed?

Yes you can, personally if you have a chip and you might want something that will last and also have good performance get the holly blue pump, just make sure you mount it closer to the fuel tank since its a better pusher than a puller versus the stock lift pump, and you can use the existing fuel lines and you do not have to worry about installing a "water trap" just make sure it goes to the fuel water separator thats what its designed for, and thats all you really need its really simple most of my friends have done that to their trucks for performance purposes, and they all love it and i am about to do that with my 91. one of my buddys actually has it where the stock lift pump is still on there and if something were to happen to the other pump all he has to do is switch some wires and and 2 fuel lines and he's back on the road. so in other words yes you can and its pretty simple.
