Have a question here... im leaking a lot of fuel from #1 fuel injector. Im trying to figure out whats the best way to replace the topside O-ring while the intake manifold is still attached to the block. Im thinking that i should be able to get to the fuel rail from underneath the car, but im not too sure. Will i have enough clearance, once i loosen the 2 bolts that keeps the fuel rail to the block, to pull out the #1 fuel injector to replace the topside O-ring? any help is greatly
