Aftermarket Power Steering Pump?

My power steering resevoir has been leaking around the cap. I checked the parts stores and none carried replacement caps. I went to the dealership and bought one for $23.

When I went to put it on the next morning, I found that it was totally different than the cap currently on mine. The new one was a smaller diameter and was a quarter turn to close type. My current one is a screw on with female threads on the cap.

I took my cap in to the dealer to show him and he told me it was an aftermarket pump. I went to Advance Auto and looked at a replacement pump and the resevoir used a cap like the one at the dealer.

For now, I found an O ring that fits onside my cap and I am going to see if that seals it up.

Has anyone else had this issue?

I've not noticed an issue with the caps, but I have seen where an OE reservoir wouldn't fit an aftermarket pump anr bis-versa.

Just installed a pump from Advance on my 98, the cap fit no problem. At least now I know what that sound was under the hood.
Grumble grumble, squeal squeal, BANG!

And the shaft fell out of the pump. Repaired in the parts store parking lot, by flashlight. Used a pulley loaner tool to swap the pulley. Luckily I had my basic toolkit with me, and for some reason, a welder that day.....didn't need that.
"That's not a real Jeep" the TJ driver said. An hour later I was pulling him out.
