Fixing old cars- I swore I was never going to do that again!!! Question for the wrenches in the forum

[Ken07AOVette]

I bought a Chrysler LHS new in 1999, 2nd best vehicle I have ever owned right after my 2000 F350 Lariat LE. I have 275,000km on the old girl, and other than a transmission at ~200,000 and rear struts at about ~220,000 it has been just great. A couple years ago it decided it didn't want to start when warm anymore. It would drive just fine, but if you touch the gas at all when it was cranking you had to sit for 20 minutes. If you tried it would not fire and there was almost a 'old kerosene smell'. After 20 you touch the gas and just 'feather' the gas while it was coming to life, and you could bring it right back to working fine. Just don't shut it off. I did several scans, changed plugs and boots, no codes but problem persisted. The damn thing still was getting over 35mpg through this.
One day coming home it decided to lose power on the road, and I had to go get a trailer. I bought a truck that day.
Now with gas prices the way they are, I thought I would go back to driving the old LHS, so I dropped the tank to change the fuel pump and filters. Actually I literally dropped the tank, when I had it on the lift it was held up with tie straps and I was slowly letting it down, something caught the gas shifted and then it hit the floor. Ripped the wiring right out of the car
Luckily I knew that the access to the tank wiring is under the back seat, easy fix but still annoying.

SO here is my question. The 'kit' I got was just the pump itself, no assembly. I can not for the life of me get the pump out of the bottom half of the assembly. When they assemble them, do they glue the 2 pieces in? Seems strange that you can buy a pump for a pickup that doesn't come apart but I have seen stupider things.
Is there any way to change just the pump?

I have already ordered another assembly and a camshaft sensor, they are a couple weeks out. From what I have read the pump and sensor are the 2 things most common in this type of failure.

It's a shame, the old car is a very good looking fully loaded leather creampuff, rides wonderful and has brand new shoes under her. I think I even did the brakes a year before I parked it. If these don't fix it though, it may be the scrapyard for my last ever Mopar.
