Leaking gas from the injectors

Hello,

It sounds like you might have dried up injector O-rings and that's why its leaking.
You will have to replace the O-rings in order the fix that leak.
There are O-ring kits that you can purchase for any auto parts store, and you can use those to replace the worn O-rings.
Use care in removing the fuel injectors in order to prevent damage to the fuel injector electrical connector pins or the fuel injector nozzles.
