Hi all,
I have to say this has been a very informative thread. Thank you to all who chimed in!!
The least I can do now is report back.
The pump is in, all hooked up, heard the pump prime with a much more pleasing buzz than the old one, and car started right up!!
A few of my observations:
Good riddance, gone with the old!!!

In with the new Delphi Pump -- great addition:

My observations on the Delphi Pump:
1. Initially it took me a few tries to seat the pump in and get the V-Clamp to hold it down. I did end up buying a 4in Vclamp from Walker #35805. My first attempts were not that great, i felt that the lower part of the clamp was not actually engaging the tank even after maxing out the tightening to where the clamp would not go no more. The pump ended popping back out. My second try i made especially sure that the pump was pushed in as far as possible and flush with the gasket as much as possible, I also made a slight spacer of weather stripping rubber to fit in the "v groove" of the clap to help the clamp grip the rim of the pump more. It did that time and held the pump in, I can also shake the car a bit if I try to move the pump from side to side. I guess that is "tight enough" just to keep the pump in place, because needless to say if I actually use my whole strength I can probably still pull the pump out by force even with the clamp on. I figure with the spare tire on it and the force the clamp already has, that the pump should stay in place .
Any other observations on this? First time using this style clamp on anything.
2. The Delphi pump has the sender arm pointing the opposite direction; the way it swings would by default cause your gauge to read F when in fact it is L, and vice versa, as compared to the DMCH pump/sender combo unit. So I went ahead and reversed the bend of the sender unit that goes into the pump 180 degrees, and played with the rest of the metal rod to where it would be a nice shape and not exceed too far out to where it would catch the ground wire in the tank.
The thing is I still have a good sender unit which is the aftermarket Delorean.com unit. It works fine, but I went ahead and set the pump up with the sender unit in the event I go upgrade later. I figure the pump sender unit will be more accurate than the default unit since the Delorean.com unit seems to read more in 1/4ths at a time.
I'll tinker with that later and work to get maybe Dave's sender ECU unit.
Here is a great link, maybe from someone already here LOL, that explained the positioning of the sender arm. I went ahead and used this to leave it setup and ready .. LOL, i hope I did it right!

3. After I started the car, I left it running for about 15 mins. There were no leaks at the pump or disconnects. I did notice a slight leak to my feed line at the hard line barb that goes into the car, so I just tightened the clamp down a few more turns and it stopped. The only thing I can attest to this is that maybe moving the lines around I disturbed the seal or perhaps this new pump has a slightly higher pressure than the old one and caused the initial small leak.
I'll keep it uncovered and check it a few hours overall to see if everything it good then I will start it again and patch it all up.
4. Oh and I did cut off that annoying tab on the rim, and a few on the top of the pump that might interfere with the spare wheel cover.
5. Also, I did not know this until now, but right above the pump on the bulkhead you will notice a hole, that hole is the drain from the windshield where all the rain water flushes down... conveniently on the pump and connector!! You can make some sort of gutter cover right in front of it from plastic to divert the splash of water away from the pump. I did so and now the water will run more along the bulkhead than splash right on the pump.
Overall I am very much happy with this setup, don't know why I didn't do it years ago!! I guess it took some annoying buzzing from a hot day of driving to make me realize it was time for this old pump to go.
Again, thanks everyone!!
