I had two injectors ohm out low and the car barely runs when warm. Ordered a set of injectors from the fleabay. I have them on but they don't look right. What do you guys think?

Fuel rail is tightened down.

It looks looks like the o-rings on the bottom of the injectors need to go inside the manifold bores. Can you move the o-rings to the bottom o-ring groove?

Spdrcr

There are two o rings. The lower one is down in there. It just doesn't look right and not too snug. Those runners are such a pain I don't want to pull them again for leaks.

Think I'll have to throw everything together to check. I should get it done by tomorrow so we'll see.

That does not look correct to me.

From the photo it almost looks like the o-ring is not in the right grove.

I'm not a Bosch injector expert; just what I seem to recall reading about them on the forum.

IIRC, with Bosch III injectors you're supposed to plug them individually into the manifold first and then fit the fuel rail on top of them.

IOW, due to the height of the injector, the injector can "float" between the rail and manifold; they need to be "biased" (for lack of a more descriptive word) downwards towards the manifold. Looks like yours are biased upwards towards the rail.

Thank you guys for the responses. I did end up pulling them out and putting them in the manifold first. I did the cockroach at first.

It didn't make them look any different. Put pressure to them by priming the pump. No leaks. Put it all together. Still no leaks and the car runs fine!

The only thing I figure is the originals only had one oring top and bottom. The new ones had the two on the bottom already installed. Maybe that ring is just not needed for my 305. Either way everything seems to be good for now.

Idk why people buy these as replacements. They are rehabed junkyard units. They dont fit because they are too short and even putting the spacer on them like the sponser who used to push these here get them seated, but the spray pattern is wrong because its to high in the manifold bung. Get factory rochestor or bosch replacments that are the correct height. I wouldnt use them

southbay08

That actually is correct. The injectors are shorter than the stock. You need the second oring to sit on the outside of the intake ... That oring acts as a spacer and gives it the additional height that it needs to fit properly
By the way...$85 for a full set of 8? Be very careful. Sometimes you get what you pay for

Thats ridiculous. Why not just get stock replacements? Your putting the spray of the injector about a half inch off of where its supposed to be. There is a ridge in there which the injector seats against. You want it spraying into the port not wetting the whole inside of injector bung. Places that sell these pull them cheap from a bone yard, clean them, then sell them and tell you it fits. The "correct" ones are not these.

southbay08

is that so....you have an aweful lot to say. Not sure why you've had problems. Speak to the thousands of people who are running these injectors who love them. And sorry, we don't sell junkyard crap

And here I thought buying replacement injectors was simple. So many opinions on them. I ran 30lb Ford Motorsport injectors on my last car with no issues but that was a while ago before a lot of this new injector technology came to light. I just want new injectors that will work correctly AND not leak.

southbay08

I don't understand where you guys have been. We've been a sponsor on this forum for 8 years....the technology has been this way since then. There is nothing new here. The bosch lll injectors fit all applications. The only issue is if you have a stock set up you will either need our adapter or a second oring. No magic to this. The ford motorsports worked out because you were probably able to use the clips. The reason for the adapter or the extra oring is because on some of the bosch lll injectors bosch didn't make the grooves in the top of the injector to use the clips. We have been and always will be available for any questions that you may have with regards to fitment with particular injectors and setups. Our number to the shop is: 516-442-4707

I will giving you guys a ring later in the year when I make up my mind on what i want to do about runner and intake options. Thanks

That's fine. We'll help you with whatever you need

I do have something to say,so what? I didnt say junkyard, I said refurbished. At $140 those are not brand new. If you go by that logic any injector can fit anything. Injector offset or ohms mean nothing I guess.Your putting the injector up in the hole, spray pattern is changed. A fine mist hitting inside the injector bung and not aimed down at the intake valve/runner. Are you disputing that? Some have had problems and some have not. Do a search and you can find that info easily. Where have you been? There is a ridge in that hole for a reason. To seat up the oring, not to fire into it.If your dead set on using these actually FIC makes them fit right. I wouldnt trust a loose oring in there. Thats just a hack way of making them fit and sealing them. You sell the originals at almost the same price, why would you turn them on to the bosch 3s? I think I know why.

southbay08

You did call them junkyard..this is what you said: "They are rehabed junkyard units."
Isn't it funny... i knew FIC was coming into this. Since we sell the same injectors Tell me exactly what he does to make them fit right... what's his magic?
The spray pattern is not affected by the fitment of these injectors. What loose oring are you talking about, and what originals do i sell...I'm not following you?? The bosch lll injectors are one of the most efficient and reliable injector out there ... customer
feedback is always awesome

Spdrcr

All I can say is they are still running ok and not leaking. Right now I am just trying to keep the 305 running until I get the time to work on a swap. That's the reason I went cheap with ebay.

You get a set from the boneyard and go through them. Resell them. Profit margin is good because there are thousands of sets in dead cars. These cant be new. New sets run in the 300 dollar range. Am I wrong?You said you stick another oring under the injector to seat up against, correct?

Why not just use the originals rebuilt. The logic Im getting is these are plentiful now, so they can be made to fit. So are they new or refurbished?

southbay08

Really, i didn't know that you knew so much about my business. You have NO idea where i get my injectors from. I never said that they were new. And the only time that they receive an extra oring is if there is a question about an aftermarket intake, otherwise they get an adapter that we designed to fit on the bottom. We've sold thousands of these injectors to very satisfied and happy customers.
Why not rebuild the old ones? Really? The multecs? We sell quality parts. The multecs are junk and are prone to coil failure. If someone offered to give me 1000 of them free of charge I would refuse. THEY ARE JUNK! You have been a member on this forum for many years you mean to tell me that you do not know anything about the multecs? I'm surprised. Anyway, The bosch lll's are a newer style injector. The spray pattern and atomization is far superior than the stock injectors. Our customers love them. Not sure why you are making such an issue out of this. I answered your question. I would like to be done with this conversation.

+1 for SouthBay Injectors, we've been putting them in C4 Corvettes at work for years without a single issue. Extremely reasonable on pricing as well, we were paying 2-3x more for the same or lesser quality before we started using them.

You can do a simple mod, use a die grinder cutoff wheel to cut down the injector stand posts about an 1/8" and install into manifold first with 1 injector and then put rail on. Works great
