Will a -10an fuel line feed and -8an return setup be overkill ? 400-1000 horsepower range. Please post any useful information. I currently have a Walbro 255lph fuel pump but plan to upgrade soon. Injectors are currently a Injector Dynamics 1000cc set.

 

What fuel pump, injectors, type of fuel (IE 91/93 octane, or E85), and power level are your ultimately planning on having?

 

‘the size of the lines should be fine, but anything over 850hp is going to require a very large fuel pump or dual pumps and a minimum of 2200cc injectors and possibly a 2nd set of injectors. I’m hitting around 67-70% duty on my 2200cc in the 700-750hp range. And as EG above stated, the type of fuel determines a lot, I’m running pump E85
