Injectors for TBSS intake with flex fuel?
I'm planning on running a TBSS intake and fuel rails on my Silverado. I have returnless fuel lines so no need for the corvette filter. My truck is flex fuel so I think it has EV1 connectors? Anyways, can anyone recommend some direct replacement injectors in the 42# range for flex fuel and TBSS intake (I think they're shorter than stock truck injectors). This will be on a heads/cam LQ9. Thanks.

The intake has 5.3 flex fuel injectors on it from a NNBS... should be 36# EV6 injectors. Obviously hey fit the intake, but I'm pretty sure they will fit your flex fuel truck too. They wont give you enough fuel to be able to run flex with all those mods but I've never seen flex fuel in this area anyway.

L59 flex fuel injector swap. Holley #40
New to this forum. Hello, My Question to anyone is that I just bought a 2007 Chevy Silverado Classic with flex fuel. Nice truck by the way. I purchased a set of 8 fuel injectors before the truck because they are new and I could not pass up for the price. The Holley part number is 522-3008. I tried to look them up but the only thing I could find is 522-308. On the package it says they are 30 pounds high impedance and good for up to 550 H.P. I am laid up right now or would go measure them myself. I believe these were designed for older lt-1 engines but just guessing. I know the flex is a higher p.s.i. fuel pump but I am planning on a holley terminator x system. It is the l59 5.3l. I am opening the package of injectors now to measure one. Ok overall it measures 2 3/4 inches. 2 1/8 inches above the fuel rail. I any of you can still clap your hands and stomp your feet please do so for me. I will again but not for a few months anyway. I think my best bet would be is to buy new injectors too. Please , any thoughts on this would be greatly appreciated.
