FYI, that system has it's drawbacks in return for more fuel delivery.Stock one is backordered of course, so Fuel Injection Depot triple pump ordered from @Nick797. Don’t really need the capacity but hopefully it’s just more durable.
The primary pump won't have a check valve anymore so tuning adjustments will need to be made to the priming cycle. Regardless, you'll deal with longer cranking starts. Unless you set to ignition to build pressure and quickly start the vehicle before the primary pump starts to bleed pressure.
The primary 295 generates a lot more heat so they advise never going below a 1/4 tank of gas and never going WOT below 1/2 tank.
I've been told by other sources that the 295 is not as reliable as the 285s. I don't have any verifiable claims to it but if true, then this triple-pump kit likely won't have more longevity compared to the factory setup.
