The holley red pump is a vane pump also. Quality on the holleys is good, better than the carter in my opinion, plus you can get rebuild kits for them for about $20. The holley red is 7psi.
No big surprises. You might want to check the pressure at the filter after you put it on. I just put on a Mallory gerator type pump that is supposed to be a 7psi pump and its putting out 11psi. I am having issues that may be related to that but I am not sure yet.
Make sure you don't run it through the stock pump, not a good idea.

I just got me an electric FP, I put it on the that big plate on the fender well (the plate that holds the voltage regulator and some other things, got me a bunch of clear hose so I can see if it bubbles, and just cut the steel line running from the racor to the main fuel filter..in half and ran the FP lines into it.. I haven't driven it yet since I got coolant problems but I am hoping I can get some smoke. I turned the screw one flat a couple weeks ago and didn't notice ANY difference.. figure this extra FP should kick it in the rear..

I have installed one before and it didn't seem bad at all. I used rubber hose from the stock lines to the fuel pump on each side and it sealed easy. The only problems I ran into is you have to find some type of stiff rod to go inside of the stock lines. I used some brake line off of an old truck we had here. This keeps the line from collapsing and pinching off.

Oh yeah and put it as close to the tank selector as possible. Any check valves should be after the pump. A fuel pump is a pusher not a puller

so you have the electric after the mechanical? Haven't heard that one being done, mainly because the mechanical is doing all the work, and the electric is just sucking electricity to do no additional benefit. If it was at the back, it can help the mechanical, although not recommended due to possibility of the mechanical failing and then the electric would put fuel into the crankcase.

I used a purolator pump on the frame rail next to the selector switch so much cheaper than the holley red that I bought a spare to throw in the tool box. Supplies plenty of fuel to get 16,000# up a 6% grade from a stop at the bottem.
