Fuel injector pressure

I have a 1990 e250 6 cyl. 4.9L van.

I noticed the #2 fuel injector appeared to have a leak and I attempted to remove it. Upon dislodging it gas splashed out from the supply port on the rail, as if it was pressurized. Is this normal or would it signify that there is a blockage of some kind? Would it affect the remaining injectors along the rail?

Thanks for any support.

Re: Fuel injector pressure

whenever you want to work on the fuel system,you should remove the fuel relay or fuse and then turn the engine over a time or two to relieve the fuel pressure in the rail and lines.If you did not do this then you would have gotten this pressure release of fuel once you broke the sealing of the injector o-ring.
