fuel injector
 

How big of a job is it to change out a fuel injector on a 280se 4.5? I have an injector that seems to be leaking at the electrical connection. While I was at it I thought I would replace all of the upper(attached to fuel line) hoses, and the lower(under the bracket)rubber rings. I noticed 6 of my injectors upper hoses are held on by an upper and lower clamp, while 2 of my injectors only have an upper clamp; and, seems to be attached to the injectors at the lower potion of the upper hose.

Changing the injectors is preety straight forward. It is best to get the fuel line kit. You will need upper/lower orings. The hardest part is figuring out if it is a CA or federal car. Fast lane has the parts.
