Loosening CIS Fuel Injector Lines Question

I'm about to replace the O rings on my injectors. The tech article recommends that I separate the plastic line (which I have) from the injector before removing it. Before I do something silly I want to verify the direction of rotation for the connector and injector.

It seems to me that the correct way to loosen the two is as shown in this pic. I would appreciate it if someone had a look and verified that I have this correct.

Thanks.

Fuel injector lines........

Paul,

The picture shows the correct position of the wrenches. Let the 14-mm wrench on the left and 12-mm wrench on the right to form a V-configuration and squeeze them together. You must be getting old like me. Sometimes I have to ask my wife to help me find the tool/s I was using earlier and have no idea where it went. Or it was on the work bench but did not see it. Stay safe and healthy.

Tony

I was surprised at how tight a couple of these were when I replaced my injectors and lines a few months ago. Vandals must have broken in and tightened them to vex me. They certainly were not leaking.
I tried the least easily accessed injector first with the 2 wrench method and then decided to remove everything at the FD as it was a bear to break the nuts loose in situ. Took them to the vise and clamped one side in the vise and then broke them loose as I wanted to save the injectors, just in case.
Hopefully, no busted knuckles in your case.

Tony-

Your comment above sounds very familiar to me. Got a good laugh about it.

With the Ball & Cone design of these fittings, no need to tighten them too much. Snug plus a little is the rule of thumb I follow.

Same with the Big Oil Lines, except with them you MUST use anti-seize on the threads, JUST the threads.

Len,

We are probably the two oldest members that are very active in this forum. With the amount of work waiting to be completed, I could stay in my basement for the next 12 months doing the things we both enjoy. Stay safe and healthy.

Last time Len and I met at Hershey, we were at the same age. And I was born in 1943. I play pickle ball Monday-Wednesday-Friday (3 hours each time) and tennis Tuesday & Thursday (2 hours each time) against players younger than my children. Most of my contemporary are not playing anymore either due to poor physical condition or health and worse they passed away. I am blessed and fortunate to be able to do things in life most people have taken for granted.

Tony

So you're both 5 yrs older than me.

It's great that you're able to be so active, Tony.

BTW I lost 50 lb about 2 1/2 years ago and have kept just about all of it off. Made a huge difference in the quality of my life.

Keep up the activity and stay safe.
