(Taken from a prev post. I didnt think the subject matched the question and would be hard to find if searched so I gave the question a new subject)
So....
for the past few months I'll drive the blazer around and occassionally I need to unscrew the the return line check valve and blow it out with some choke and carb spray. A bunch of tiny coffe ground debris comes out and I then reinstall and along my merry way I go for awhile. Then the rough idleing and loss of power returns. Weeks usually go by and I might have to do it again. Then this past week Ive had to do it every other day.
Ive heard the thoughts on changing all those lines but is it really the problem? If they had deteriorated so badly I would think there would be fuel leaking from one of the injector return lines.
Breaking the bead inside the check valve is not an option as previously posted since this affects the cold advance and makes cold starts even harder on the motor.
