Will '88 fuel pump work in '84?

[Tha Driver]

Soooo, I think the fuel pump id failing in my Indy...  Will the '88 v6 fuel pump work in it?

The88 V6 or any Fiero V6 pump won't work in it, but unless the harnesses are different, they should work.  Ashby replaced the one in my 88 coupe with a used one, but I don't know what year it came from. 

According to The Fiero Store, the same pump fits all year 4-cylinders.  Rock Auto agrees, listing the same numbers for both 84 and 88.

OK so the '88 V6 pump has different wiring connectors. I'm not going to try it 'cause I don't want to pull the tank again if it doesn't work.
I bought a Carter from Rock Auto & it is garbage. First, the wiring is different: instead of the original wiring bolting on, it comes with a *press on* connection & a separate pigtail - which you have to solder in. Then the pigtail has TEENY-TINY wires that couldn't possibly carry the current to run a pump!
So now I'm waiting until I get the money to buy a pump locally, while I jump through the hoops to return the Carter crap. (I have to find a way to print the return label). Sigh...

The V6 fuel pump supplies to much pressure.  The Duke pump is a lower pressure pump.  You might check with AutoZone.  Look at the Delphi pump that comes with the harness, and the rubber O-rings for reinstalling the sending unit.  You'll have to buy a sock filter separately, but that's common with most fuel pumps. 

Can you email me a picture of the harness on your pump?  Or look at the harness on this one from Auto Zone.

Here is a pic of the wires. Notice that the Delphi pump you linked to also has the press-on electrical connection at the pump. Does look like bigger wires, though. I did buy a sock, as mine was... rough.

I've used several Delphi pumps, but only for a V6.  All were plug and play without splicing. The pumps were good, except for the last one I got for the 86.
