I'm getting my 3.4 Formula running again after sitting for years. Long ago, I installed Accel injectors, and they worked great. I removed them to clean in an ultrasonic cleaner (as recommended by Matt Meyer). After reinstalling them, I noticed the rear bank was leaking at the base. They weren't totally 'clicked down', so I removed the fuel rail to try to reinstall them properly. I also noticed the #5 cylinder injector was leaking at the top, and discovered the o-ring had a small chunk taken out.
Bottom line, I need to know the proper size for replacement o-rings, both top and bottom. I would assume the size for the Accel injectors is the same as stock given that they are installed in the same place. I've done the fuel rail several times, but for some reason this time it doesn't want to seat. I normally rock it back and forth a bit to get all the injectors lined up, in place, and seated. Any tricks for this I'm missing? Thanks.
