i got a 302 FI v8 in my 86 ford bronco and on the fuel injectors theres a bar that goes across all of them and at the end by the cap and rotor theres a place where it looks like a air hose goes on? is it for like cleaning the fuel injectors? it looks like a stem on a rim on the wheel where you put air in, i dont want to try it because its a daily driver dont want to be walking are takein the buss thanks guys any help would be good

 

if your injectors get clogged theres a kit you can buy where you plug it into that stem piece and it blows out anything that can clog up the injectors, im pretty sure a local auto parts store has these kits

 

You can also use this valve to release line pressure before you remove any parts on the fuel line.
