Do you guys know if Fuel Injector Connection still in business? Doesn't answer or respond on phone or email, any clue?

Are you talking about this place? https://injection-connection.com/

I can tell you that they haven't posted on their Facebook page since May 2023. But it doesn't seem like they post to it very often. So many that doesn't even mean anything.

It's Fuel Injector Connection in Georgia; finally got a hold on the owner, still in business.
