Tell me more about the E2000 fuel pump

[K2ZJ]

I searched and didn't get the answers I need. I saw a reference to a $40 eBay E2000. I looked them up but I only found Fords listed. I have a 95 ZJ with no return line and I was just going to swap in the Eagle Vision FPR. I figured while I was in there I would put in a new pump. I found an E2000 for a Jeep @ $110. Are you guys using inline pumps without a FPR in the tank, are you adding a return line, or is there one that can swap in the tank. Please tell more about this, thanks.
