'90 leaky fuel injector

My '90 fuel injector is leaking and I was thinking of taking the fuel rail off and replacing the seal.

Is this possible, and has anyone done this before? If so any pointers at all?

yeah this is a comman problem with the SOHC’s. You need to replace the O rings. Should be in the service manual
