This Fuel Delivery Kit features an EFI grade 255 L/PH inline external fuel pump that is suitable for engines making up to 600HP. (Note that some of our EFI kits are limited to less than 750HP due to maximum usable injector sizes.) This kit also includes 20-feet of EFI grade fuel hose suitable for both the inlet and return lines between the fuel tank and the engine. The kit includes two billet fuel filters, a 100-micron pre-filter and a 30-micron post filter. The hose and hose ends are push lock style for easy assembly.
