Magnafuel and Weldon both pay contingency and are excellent pumps.
I run a Magnafuel pump on my SG car and love it , so far better than the previous Barry Grant and QuickFuel BG Clones .
That said ,a lot of the Stock /SS cars I build get a Aeromotive A1000 pump and return style regulator.
It has proven to be a really bulletproof pump for both my carbed and EFI customers cars, one advantage is the ability to mount it just about anywhere.
No matter who's pump you buy, be sure to use a quality stainless screen filter before the pump.
