The fuel rail side.... all 4 broke while I was trying to remove them. Making sure its still good to use them.

Here's a picture

 

Yes, buddy of mine broke them on his opel injectors.

 

Do you remember if he reinstalled the broken piece,or left it off?

 

Can anyone chime in? Im sitting here waiting on an answer so I can finish the car!

 

Since I couldn't get an answer from anyone I left the broke plastic tip/top hat off and reinstalled everything. So far so go no issues.

Theres your answer for future reference....

 

Its good to see someone actually give an answer to there problem and not a dead thread ending in nothing.

I think it would change or mess up the spray pattern, So free bump if anyone else has experienced this.

 

I have no idea that's why I didn't answer. I have to figure they are important or else they wouldn't design them this way.

 

nozzle is on the other end

 

Which injectors are those, I don't recall seeing that piece on the LSJ ones.

Having that piece on there would cause it to draw fuel from the middle of the rail instead of the bottom, so maybe they do it from factory to reduce chance of contamination? But it really won't affect anything.

 

Lnf injectors right?

 

Yes they are LNF off a 2010

 

if the tube is broken you cant use them.

 

is what zzp and everyone else says anyway

 

I've heard different. My car also runs perfectly fine. STFT and LTFT are the same as well.

 

Thats good to know. I dont know why zzp would say that then other than to just avoid any problems that could be caused by it.

 

Ran so good I blew a chunk out of my intercooler endtank at 25psi hahaha

 

Hahahah nice

 

Just following up on this. Mine were all broken also. At first I thought I did it but the next 3 I pulled I was super careful and they were broken as well. Car seems to run fine, but as 63 Nova says, why would they design them this way? Interestingly enough, the stock LNF injectors don't have the tips at all. I would really like to know why they are there and whet they do. I wonder how many people may have broken tips and not even know it? So far I'm not having any issues, I'm wondering some time later if all is still well?

 

I feel like I remember someone (maybe tomj) saying those always break on removal.

 

Yeah I think it's on his build thread.

 

If the stock injector doesn't have it and it fits with no leaks then who cares? It really doesn't look strong enough to do anything helpful.

 

Iv broken thosw every time i take out opels, not sure if they can be reused. I never do

 

Hello GoodSpeed,

We usually suggest that you don't use them after that because we have had customers and our own vehicles experience misfires at higher fuel pressures when the tabs are broken. We even went as far as to purposely break off the tabs on a set, try it, and then try ones with the tabs not breaking off.

While the vehicle may be drivable and mostly uneffected, it can cause issues higher up.

 

So how do people prevent breaking them?

 

Being EXTREMELY careful. They can be taken off by normal means, but just requires a lot of patience.

I believe there could be a specific tool to buy for removing them. I would have to look into it again though.
