  What fuel pump and regulator do you recommend for an 900HP 540 BBC bracket dragster? (Nothing trick) It does have Mikes Fab Shop S.S. headers with an O2 port in each header. and can I use my 7AL3 box? 4500 stall converter, 1900 LBS with me and ran 7.90''s with a conventional 4500 setup and belt pump on gas. (It is a Enderle 7 GPM fuel pump) Will this pup work? or should I sell it with the carb? Thanks Bob Lupini

  Answer

  Fuel system recommendations are in the instructions. https://documents.holley.com/199r11322r.pdf That being said, the 12-1500 is the fuel pump that we would recommend for your application.
