Flex fuel injectors - The 1947 - Present Chevrolet & GMC Truck Message Board Network

JAKA · 05-30-2016, 03:44 PM

My 5.3 is from a 02 DBW flex fuel YUKON. I am using a wiring harness from painless and am changing to cable operated throttle body. Does anybody know if there might be any issues with using the flex fuel injectors and fuel rail? I'm asking because I read where the injectors have a higher flow rate and also the fuel pressure specs were lower. This a return style system. I know the electrical connectors are not the same as regular injectors. I have the 381 fuel pump and the computer was programmed for gasoline only. THANKS
