Chevelle LS conversion fuel system question

[71RS/SS396]

I know everyone is on a budget and likes to save money but, this is one area where I think people make a mistake and try and save money and then put up with sub par performance because of it. My only experience is with the DSE Rock Valley and standard pump in my wife's car which suffers from starvation below 1/4 tank and my car which has the DSE tank and the Vaporworx upgrade, imho this is the best system on the market, I've run my car completely out of fuel without any warning stumble before it quit. I like the fact that it uses an OEM pump that I can buy at any GM dealer if I need a replacement and the fact OEM's do more stringent durability tests on their pumps than any aftermarket pump mfr. can afford to do. Do you're homework on this since it's far more expensive to buy the "CHEAPER" system and rip out and install a proper system later.
