flex fuel injector in (non-flex) truck manifold Hi all. I’m looking to swap 25326903 flex fuel injectors into my LQ4. I have PCM tuning, and harness adapters figured out. The flex fuel injectors are about 3/8” longer than the truck injectors, so I plan on spacing my fuel rail out to compensate.
My question is, what o-ring I need for the manifold side of the flex fuel injector. The OE flex fuel injectors have a smaller o-ring than the truck. Using the truck o-ring makes for a very tight fit. I’m curious what others have done to address this?
