Default New member with fuel pump wiring problem

I have a 96 3.9 and have removed my faulty fuel pump. The electrical connection has 6 wires. I have a fuel pump for a 94 and the plug for the electrical doesn't match, and only has 5 wires. I would like to be able to remove the plugs and hardwire it but my local Dodge dealer has been no help in telling me what wires should be connected.
I'll list the wiring colors if that will help. My truck has been down 3 wks now and I sure appreciate any help.
1996. Grn/blk. Blk. Blk/wt. Blk/lb lb/blk db/yl
1994. Grn/blk db/yl. Lb/blk. Blk. Blk/wt.

Thank you

Get the correct pump for your year. Otherwise, you are only introducing new problems.

What he said. A fuel pump is something you wanna get right the first time because it's really annoying to drop the tank or pull the bed twice.

Return or sell the '94 pump and buy a '96.

Whereas I understand that a high quality new pump assembly pushes $200 (Denso 15 gallon pump $172 plus shipping at RockAuto), using a used fuel pump is a false economy IMO; due to the pain and effort of handling a full fuel tank when the used one quits.

I learned the HARD way to not cheap out on fuel pumps on my 2000 Malibu; I was averaging 30,000 to 40,000 miles per pump on the Airtex pumps, but the Delco it had in it when the hose blew and killed the motor had over 65,000 on it at the time.

(Even the free ones my nephew, who owned a wrecking yard at the time, were getting me cost me money since I didn't have a lift, and the tank was long enough there was NO way to get to the pump with the car on jack stands ... )

Like tbugden and HeyYou said, just get the right pump, correct year.

If you don't want to do that, order the gasket, strainer, and a stand alone pump (I'd opt for a Walbro, Denso, or Bosch if I were you; stay away from the no-name ones) and rebuild the current assembly. Be SURE to use hose rated for immersion in E85 while you rebuild (don't run E85, but make sure it can TAKE running E85 ... that way E10/E15 or so won't even be noticed!)

That should get you out for about $100 or so.
