Removing Injector Lines from Injectors

I was in the process of doing some maintenance to my 87 and was replacing the injectors with a new set and it seems that the line fitting on the injector is very........uncoperative. I initially tried PB Blaster, but the way the fuel line attached it really is pretty hard to get any fluid to seep upward the way the set up is. I didnt want to break anything, so I have resisted and then I switched to a 50 / 50 mixture ATF and Acetone. It worked for me on other stuck / frozen bolts and spark plugs. Now it will stink up the garage. Any suggestions or just wait a bit longer. Here is a picture of the dilemma. Thanks in Advance Marco Image Unavailable, Please Login

 

That was actually what I tried 1st. They are rusty and can only imagine what they might look like inside. I am trying to be patient.....for a change, just afraid to put too much torque on them. I might try to hold the injector nut with a wrench and try to spin the actual injector. Thinking that I would be less likely to break a line that way. Maybe some Extra Virgin Olive Oil??????? I appreciate the suggestion. Thnks Marco

 

I was using an open end wrench on the injector as that is all that you can fit in and a line wrench on the fuel line nut on the top. I think I willl try to squeeze together as you suggest using the V method. I get it. Thanks Marco

 

Vincenzo, Agreed that most of the PB Blasters and WD-40s dont really do alot for nuts / bolts that are really stuck. I have heard the Kroil and the ATF / Acetone 505/50 mix are the best. I did get 2 of the six loose on the Drivers side.......maybe.......I am getting old and weak..........I think maybe a set of longer wrenches would do the trick also. I appreciate it Marco

 

The Brass Bosch 0437502047 injector. I have new rubber O Rings for them also. I do have the cleaner set up to actually try and clean the injectors, but ran across a great deal on the new injectors awhile back, so they have been sitting around. I just had my Hip replaced so I got some time to do maintenace / upgrades etc. I think I will test the old injectors and keep a log to see when they open and spray pattern and if they leak etc. and then try and clean them and see what happens. I am a wanna be engineer!!!! Thanks Marco

 

Great Info.......It is addictive and I apoligize for lack of good pictures like our man Shamile!!!!!

 

Doesn't the circlip actually hold down the aluminum insert that the injector basically fits in to.? I can see the circlip on top at the outer edge I believe????

 

I havent tried that, but agree while it is in all I can do is an open end wrench on the injector and a box end wrench on the line fitting. I am trying to have patience and could certainly not make any money professionally at this. I really do have to give it to all the priofessional mechanics here.........nothing in life is easy!!!!!!

 

I might move on to something else. I was also going to change the trans fluid and that might distrach me enough to let the mixture I sprayed on it work in a bit????? I got time but no patience. I think I need longer wrenches also so I get more leverage. Thanks for the suggestions. These are absolutely original you can see the rust on the upper body of the steel.

 

I will do my best. Definetly will look at the oil. I have a lift and an oil catch can with a screen in it. Thanks for the advice. Marco

 

Well I got sidetracked but managed to get the 7-9 injector lines off. Pulling the injectors..................well that is another story. Felt like I was just wasting time, so I pulled the lower intake off that holds the injectors and basically punched out the injectors for underneath. They wanted to fight me a bit, but I was able to push them out. What a bear and now I can see why the professionals get paid for what they do......,I am going to remove all other lower portions of the intake and if I can get the injector line undone while on the car I will remove the line from the distributor and remove the lower intake with the line and deal with it. I figured I need to look at the lower intake inserts to see their condition for the new injectors anyway. I do have a new set of new insert sleeves for the intake. I did run into a guy here in Baltimore at Cars and Coffee that has a small manufacuring company and offered if I ever needed a small part made to make it. I thought about getting him to price out what it would cost to manufacture the inserts where the injectors sit in the lower manifold, as I believe they are hard if not impossible to get. Any ideas if that is worth it??? Thanks Mark
