Default Injector issues

I have just registered here and knew this would be the place to come with help
I have a couple of bad injectors on my 1993 corvette convertible. I have ordered
and returned 5 sets of injectors because none of them matched the ones I have
taken out. The last set was bought online for a 1993 "ONLY". They were Rochester
OEM or so they said. The are to short and did not match the OEM that I removed.
How many different injectors came out in the 1993. I have attached a picture of
the latest. The one on the right is the one I removed. The one on the left is the new one
I hope someone has ran into this before. Thanks

Those look like Multecs. Why would you want them again?

I thought they were the original. I really don't have a preference of brand as long as they are the right ones.
I have ordered 5 sets and none match my injectors and none have the correct length. The original ones
are exactly 3" end to end

Give FIC a call but I don't think they need to be exactly the same length. I would not go with Multecs because they are susceptible to ethanol. That way I can fuel up anywhere I want. Are you saying they don't look like the original or just the length? I don't have a stock manifold anymore but I think the injector length has some give.

I have installed several different lengths and they all leaked. The only ones that did not leak were the originals. All were to short and the fuel rail would not bolt them down to seal them

Give FIC a call. They might be able to get it done. They have for many

I gave them a call and ordered the Bosch 3 fuel injectors that they have (for only the 1993 Corvette LT1)
I should have them Friday. Thanks for the recommendation

You did not forget to tell them about your fitment issue, did you?

These are for the 1993 LT1 and are the exact same. The length of the bottom cap is not critical. It can be slightly
longer or shorter and still seal using 3 o-rings. One of top at the fuel rail and 2 on the bottom of the injector

Thanks to all. I received the new Bosch 3 injectors and installed them per their instructions and the car now
runs flawlessly and sounds better than ever before. Great results
