Why? My Idi will run off a 9v battery why would I want to ruin it with an electric fuel pump? The system was designed around a mechanical lift pump. It has worked great in my truck for 35years. Why any one wants to swap to an electric I don’t understand at all.
I'm getting ready to rebuild the 92 idi with a few changes.and the fuel thing might come into play. the truck is a 92 f250 E4OD 3:55 4x4 reg cab. it's getting ready for retirement, the 650 handles the work load now
I'd like to help you understand.
Replacement mechanical pumps are (generally) c**p, these days.
I ran a Delphi version of that carter pump you're referencing and it didn't have sufficient flow under load at RPM. I was running into fuel starvation issues pulling hills. The carter could be different but I removed my Delphi e-pump and went back to the mechanical, the problem went away.

How long have you had the Holley ? Some say the Holley has had problems but now a days who doesn’t. Forgot to mention I’ve been gathering parts and pieces for a year and a bank’s sidewinder is ready to go on when the engine is done

I had it for two years, when I first started out on the idi journey I installed a faccet fuel pump, then I found out it does not have enough volume. I use it for a pre filter for the holley, but added a switch to it for a back up, incase the holley quits.

I strongly agree. When you run WMO though, it's hard to beat a mechanical pump. I know guys say the Holley red and black will pump the WMO, but I just don't want to gamble on it. And like @chillman88 said, the mechanical pump really does appear to do a good job at keeping up with demand. Both mechanical and electric pumps break at some point.......pick yer poison!
Edit, I made a thread "another air intrusion thread, but just for fun" where I propose the idea of mounting your fuel cell on the top of your truck and using gravity feed......it didn't catch on though.
I ran a Holley red on the rv in my sig for 3 years, before i sold the RV.

They might, but I don't know how well. My Holley blue doesn't like straight dino diesel when it's cold and thicker. Since straight WMO is thicker as well, I'll bet that they REALLY won't like that stuff when it's cold outside.

Don’t know wmo but have made bio. Either way cold weather is not a factor down here. We combat heat like you fellas combat cold, and now coming into rainy season….anyway I like the rotary pump idea and put the thing where you can get to it easy. And it’s not rubbing on the cam making drag and tiny metallic pieces

I'm in NW Florida, and it does get cold here.....it snowed 7-8" a month ago, lol, that's not common obviously. But even this morning it's 40F on my porch and my truck wasn't too happy about it. Anyway, gimme a mechanical pump!
