Problems installing new fuel injectors
Okay so I purchased a set of injectors from southbayinjectors recently. I got everything apart and was working on installing the new injectors into the fuel rail. The first thing I noticed is that the replacements are slightly shorter than the stock injectors. When I placed them into the fuel rail, using the retaining clip that came off the old injectors, they seemed really loose. I took the retaining clip off and firmly seated them into the rail, but then I couldn't use the retaining clip. It didn't match up with either of the two slots on the new injectors. First question, is the retaining clip necessary since the fuel rail will be bolted down to the intake? I called southbayinjectors and they told me I would need to add a second o ring to the end of the injector that goes into the intake. Second question, is this going to resolve the length difference and am I going to have an issue with leaks? I sure hope not as this is my daily driver and I need to get it reassembled asap. These were advertised as 19lb Camaro TPI 305 1985 - 1988. I've attached a couple of photos of the injectors to look at. Has anyone else used these particular injectors and if so, how are they working for you?

Re: Problems installing new fuel injectors
be careful with those injectors. i looked at the pic and it shows rust under the plastic.. this could be very serious as one of my jeeps had the same thing.. the injectors started to leak through the case. .. They look like they we really rusted before someone cleaned them up.

Re: Problems installing new fuel injectors
Most just install without the clip, push the injector completely into the fuel rail. The clips were there for assembly line install to keep the injectors off the floor.
The extra o-ring is for the design three bosch injector (see pictures in other posts) you have design two type.
The only other thing people have done, on the design two, is use the GM o-ring which is a little fatter (tighter fitting) then the normal ford supplied o-ring.
When I installed 24# design two's in my TPI, I used the clips and the fatter o-rings, worked fine no leaks.

Re: Problems installing new fuel injectors
Granted you will take care of it. All I am saying, and I am not putting you down, is that to me they have rust coming out of the top. Look at the picture the poster put up. If you went to an auto parts store and they tried to sell me something that looks like that I would not accept it. Either would you. If they have a problem you say you will take care of it.. What if it is already burned up like my 2 jeeps. Been there done that. You defend these as remanufactured, Ok, thats your opinion, my opinion is they could fail and ruin a non replaceable car. Just trying to look out for my fellow enthusiasts. I have been on this forum for 8 yrs, I have seen to much to know I have seen too much. Be a good sponsor and send the guy some parts that arent cleaned up rusty old parts. Thats all I ask, But, its really none of my business anyway. Safety first..

We sponsor this forum and others,,,to help out as much as we can, and if someone is not satisfied or happy with their parts all they have to do is give us a call and we will be happy to help them no questions asked. There is no reason to call our product rusty old parts,, that is uncalled for, but yes, safety is of the UTMOST IMPORTANCE!!!

Re: Problems installing new fuel injectors
We would not tell you to do something that would not work. You are not going to have any leaks. These injectors are the same length o-ring to o-ring as the bosch lll's and they are also 1/4" shorter and that problem is resolved with a second oring That second oring is what makes up that 1/4" difference. You can measure it and you will see what we are talking about....GUARANTEED!

Re: Problems installing new fuel injectors
To me a remanufactured part looks like new. I just ordered a starter from the states. It looks like new with all new internals.. What do you do to remanufacture a fuel injector. To me this looks reconditioned. You keep answering so I suspect you are interested in customer feedback. So why would you want to sell parts that look ugly.. You have to admit. That injector when you blow up the pic is ugly. There is chips in the plastic and has dirt or rust in the little silver part under the o ring goove. Again, not trying to bust your chops but is this the way they all look like.-

Reconditioned, remanufactured...same difference. As far as what they look like i do not know what you expect... they are USED and sometimes you can do only so much to make them look "pretty". It's like putting a dress on a pig...it's only going to look so good. (lol) I don't know why you are so concerned about the way something looks, I would be more concerned on how they work! When we receive injectors that customers want cleaned and flowtested, what do think they come to us all shiney, no chips, no rust come on now. My point is that we have sold many, many injectors and have never had a complaint or a problem with them. To me that is a pretty darn good record and shows that we do sell the best "quality" product at a fraction of the cost.

Re: Problems installing new fuel injectors
When the injectors are installed into the intake, the second oring does not go into the intake also, it remains on top. When they are installed into the rail, it is that oring that prevents them from being pushed all they down into the intake thus giving you the additional 1/4" that you need for them to fit. If you are uncomfortable with this even though we guarantee that they will fit 100% give us a call and we will refund your money. Sound fair?
Re: Problems installing new fuel injectors
Rust is like cancer, that injector never should have been rebuilt. Rust is in metal, and will spread, unless the Iron Oxide is dealt with chemically. Once the rust gets under the plastic, it is too late. That will at some point grow and separate the injector body from the plastic causing a dangerous situation. I would not use those injectors.
That injector should be replaced. Period. I wouldn't use it.

Re: Problems installing new fuel injectors
You want to see rust? You should see the injectors that are sent to us for cleaning, by the time we are done they look great and the customer is very pleased. Listen, I do not want this to get out of hand, I offered a refund or exchange to the guy, what else do you want from me what more do you want me to do? Besides, if he is unhappy then he should be the one to call or contact me, I understand that you guys mean well. We are very easy going, and try to offer the best customer service out there we do not want anyone to be unhappy and we will do anything to make them happy....but man you guys are always so ready to just bash. I would like to drop this now. We will be more than happy to do whatever the CUSTOMER wants us to do.
Re: Problems installing new fuel injectors
Look, we all know there may be a times some slip through the cracks, but honestly, there are some cores that should never have been used. Just because someone sends them in, doesn't mean you should use them. I think that is the greater point. Like catching a kid that does something wrong, just because they fix the problem, doesn't mean he was right in creating it. Why would use those in the first place?

Re: Problems installing new fuel injectors
No, you are correct , but if a customer requests cleaning and does not want to purchase a different set there is nothing that we can do about it it their choice not ours. Yes, it is not a perfect world and things do happen and some do slip through the cracks which is probably what happened here. What should have happened is that the customer or one of you, after seeing the picture should have notified us about the problem and we would have been more than happy to deal with it, but NO as mentioned before everyone is so ready to bash. Now our greater point is that we will do anything!!!!! to make our customers happy what ever it takes and that should mean something to you guys.
Perhaps eight just slipped through QC.
Re: Problems installing new fuel injectors
[quote=jsup;4155160]So you admit there was a problem. I do not want to bash, not my intent, just want to see a vendor support the product they put out before they separate someone from their money. To say you will do "anything" isn't the point. The point is those never should have gone out in the first place. Then you wouldn't have to fix it. Just sayin'.
Perhaps eight just slipped through QC.[/quote
What in Gods name do you think that we are saying, of course we support our products, we want to uphold our reputation, in all honesty this is the first time that i ever had to deal with something lie this, what i am saying that if the customer thought there was a problem all he had to do is contact us, it is that simple. But this post keeps going on and on. It must be great to live in your perfect world. Show me one company that hasn't had one return or another, including mega companies, people receive defective or broken items, things happen and all that should matter is how the vendor deals with it. Now I do not have to or want to defend myself or my comany any further. We do have great products and impecable customer service. So can we drop it now????

Re: Problems installing new fuel injectors
[quote=southbay08;4155188] Consider it dropped. If I were the vendor, I'd just send out 8 good ones, tell the customer to throw those away as the core is unusable. But that's me. Not quite sure how this goes on so long. You have his address right?
Times are tough for everyone, people don't have money to throw around, they scrimp and save to get parts, and I think the fix is as simple as outlined above. Suck it up, just say they never should have gone out, and new ones are in the mail and fix the QC problem that let those through.
Just sayin'.

Re: Problems installing new fuel injectors
I am uncomfortable with these injectors and will be returning them tomorrow for a refund. I will also return the extra o-rings you sent as I received them today.
Re: Problems installing new fuel injectors
Cool, post the results. Nice to see a vendor admit when a product should not have gone out a particular way and step up.

Re: Problems installing new fuel injectors
are you guys going for a show car, or quality and reliability?
I'm sure a lot of the injectors sent to south bay are NASTY and im also sure they do their best to make them look in their prime.
If you get one that might show a little rust, SUCK IT UP its part of buying a "remanufactured" or used part. They flow test it way beyond what their daily use will be, they claim to have no problems, and if there IS a problem he's said he'll fix it.
Don't fret over a little friggen rust, put on the second oring, get your car running again and be on your way.
The original poster didn't say a word about rust...the peanut gallery did. Whos to say the peanut gallery wouldn't buy NEW from the start, to avoid any unsightly rust?
I've never dealt with southbay but GOD people on here bi*ch about vendors too much.

Re: Problems installing new fuel injectors
Just to add more, I too bought injectors from south bay and thought they looked pretty good compared to the busted up old stock ones I gave them from my 305. They've got great service, quick responses to e-mails, and seem to be a pretty honest group of folks. I do need to hit them up for the extra o-rings though *hint hint* because mine are leaking like a stuck pig from the rail. Are the GM O rings (fuel rail side) bigger than the ones on the ford injectors?

Nice acting here !!!!!
Re: Problems installing new fuel injectors
Great research Turbo! I don't have much to add here...I don't even have a mullit on wheels like you guys. Just a TPI 305 in an old truck. There is some good technical info here however and have learned a lot. I'm not even on the same coast as southbay and will probably never need injectors again so I have nothing to gain. ...post #2 thanks for making it a pleasant one Calderone.

you means,****** maybe ?
There is some good technical info here however and have learned a lot.
You're right, Amazing info !!! So amazing that can save your car
from being burned !

I have nothing to gain but protect another members property,answer me
would you feel confident with those rotten injectors ? Maybe you like rust.-
post #2 thanks for making it a pleasant one Calderone
You're welcome,if you need anything from me,i will gladly assist !
If you like reality,check the pic i posted above,if you can't handle the truth
better hide and let's say those injectors are TERRIFIC !!!!!
Re: Problems installing new fuel injectors
Since the orginal poster had his problem corrected consider this thread done. If you want perfect injectors then buy new, enough said.
