I have ECS Fuel System and I have no issues! ! My car is a 383 Stroker with A&A Kit, I am making 13 Lbs. of Boost and my fuel pressure is 60+ Lbs. My internal pump runs all the time but the external pump is only used when the car goes under boost! ! I have not seen under 60Lbs. since last year! !

I have the ECS fuel system with a hobbs 1psi pressure switch (purchased from Coolmist . com)...At idle I'm at 55psi and once I hit boost I hit 60psi all the way through 10psi. Without the Hobbs switch the external pump runs on ignition switch and in 100* weather the fuel pump was dying due to captivation.

ECS fuel system here. The kit just works. It's a little pricey but there are plenty of users out there with the kit not having issues at varying levels of power (including plenty of 700+ and 800+ cars).
Not saying it's the only solution, but if you just want to get something that you know will work -- the ECS kit will get you there. If you want to spend some time tinkering you could probably save a few bucks.

Please let us know how many ECS fuel systems you have personally installed.
I don't see the link you posted as a supporting vendor either...
