Their pumps seem to be getting a rep for dying a lot. Maybe its from how popular they are but I seem to see that often in my online travels, besides that they are noisy.
I dont know the specifics of your car but do you really need a 400lph pump?
The supra tt pump does 260lph(43psi) @ 12v and 290lph(43psi) @ 14v, good for about 650hp at 12v and 775hp at 14v.
And its quiet, and a toyota part, and no mods needed, unless you send more power to it.
The above was taken from the fuel mod page on this site;

Theres also a really good article here, it was written for dodge stealth guys but the numbers and flow charts are interesting

The write ups conclusion on the Supra TT pump;
"The Denso fuel pump 195130-1020 (the Supra Turbo MKIV pump) is one of the best in-tank upgrade choices if you are using injectors up to 550 cc/min and are providing at least 13 volts to the pump. When 18 volts are supplied, the Supra pump is good for injectors up to 880 cc/min. At 13.5 supplied volts no other in-tank pump, except for the R33 Skyline GT-R and A'PEXi BNR32 fuel pumps, flows significantly more fuel up to 70 psi line pressure or 27 psi boost. It is a direct drop-in replacement; all other non-Denso choices require some modification to the fuel pump assembly. It is as quiet as the stock pump. Best of all, it can cost only $180 at Conicelli Toyota. One disadvantage of the Supra pump is its relatively heavy current draw (at 13.5 V, 16A @ 43 psi, 19A @ 70 psi) and large decrease in flow as supplied voltage lowers. Good, heavy-gauge wiring (meaning re-wiring the fuel pump electrical circuit) is a requirement to get the most out of this pump."
