Do I need to remove the fuel tank to replace the injectors on a 98 Road King or is it easier to pull out the air intake assembly?

And should I buy genuine HD or is there a better aftermarket option easily available?

 

I think it would be easier to pull manifold. You might as well replace those seals while your at it and replace the Air Intake Temp Sensor if it has never been replaced as well. Can I ask why you are replacing injectors? Reason I ask is I have been around this forum for a while now and read it almost daily and I don't ever recall seeing a post about bad injectors on a MM system.

 

You will have to jack up the back of the tank, and put a block of wood in there. You should not need to remove the manifold.

As the previous poster stated, why do you need to replace the injectors?
