Hello, so I recently just swapped in a B16a into my 93 Integra DA and put a AEM Fuel Rail on the b16, I am now looking to install a new Fuel pump and was wondering, with the rail should I install a Stock Fuel Pump or would it be better to install a High Flow fuel pump? Does that matter at all??

 

Unless you're using a turbo or supercharger a stock flow fuel pump will be fine.

Walbro 255lph or Grams fuel pump also acceptable, I know there's a lot of other brands out there as well. I wouldn't go over the ~255 -> 275lph range though because after a certain point the higher flow fuel pumps need more electrical power to run properly.
