Need to remove TB to change #1 injector o-ring ?

Just wondering how easy it would be to change out the o-ring on #1 injector. Saw a video where the guy removed TB and bunch of other stuff. Could I get away with just removing the intakes, unbolt the one side of fuel rail and lift up enough to swap that o-ring out? It is the first one on the left hand side. Have had a leak on it for a long time but it has gotten worse and I really want to fix it now. My local indy quoted 3 hours just to change out the one side. no thanks. I cant see how it would take more than maybe an hour for the one side .....

Yes you can remove one surge tank and get to the injector.

Not complicated

Not a difficult task, you already identified the basic. Get your hand on WIS it explain step by step & make sure you use torque wrench to tighten bolts to specification.

You really should replace them all. Chances are they are all worn and once you manipulate the position of the rail and other injectors you will probably create another leak.

Thanks guys. Someone had mentioned that the stock o-rings are a little fatter and might seal better. Was thinking about trying those.

So I dont have to remove TB or anything else ? Might finally tackle this tomorrow.
