injector size question when swapping 2001 engine from flex to gas only -

Hey all, I plan to put a gas only engine (2001 3.0) into my Flex fuel truck. I saw Ron mention in an old thread that doing that don't matter but the injectors are diff sizes. Just wondered if my flex injector set will still fit the fuel rail on the new gas only engine?

I guess the computer on my truck wants to see flex injectors and it'll make me run lean after the swap - so want to avoid that. Any one dealt with this? Looking forward to getting that nice juicy 16 mpg these things give you on a good (downhill) day.

Thanks Caleb
