Need help finding part for my 86 MR2

Let me start off by saying that I don't know about engine's, So I apologize in advance. I have an 86 MR2 with the AW11 engine.
What I need is the o-ring(gasket) that goes where the fuel injector goes into the lower manifold. It might be called a lower manifold or injector o-ring. It's a part that doesn't come with the fuel injector. The ones I have been told were the ones I needed did not seal and it leaked. Can anyone help me get my MR2 back on the road.

Thanks in advance,
Kevin

This link might help you see what seal is the one you need. There are 2 for the injector between the fuel rail and the head.

FUEL INJECTION SYSTEM / toyota | part list?JP-CarParts.com

23291 is the rubber isolator sealing the injector to the head. This is more for air rather than fuel. Stops vacuum leaks.

23250B is the o-ring sealing the fuel rail to the injector

23250C is the grommet that acts as a spacer to the fuel rail and injector.

I have this kit,

Fuel Injector O-ring Kit 4A-GE / 4A-GZE, KBOX.ca

If you order the kit I'll toss those grommets in for free. Just leave a note when you check out.

Not sure where you're located, but if you are near a Napa autoparts store, get part number ATM-IK2401. The bag contains all the seals and orings for a single injector, so you'll need to get 4 sets. Last time I bought them they were $1.69 each.

Sorry to threadjack but what is included in the E51 tranny seal kit? And is this the proper kit for an 89 SC with 5 speed? Is this kit required when doing a clutch job, or to rebuild the tranny?
ps i have many more or your products, just purchased through twosrus

Bringing this back from the dead...

So I am a little confused. All of the fuel injector seal kits seem to come with only the upper and lower "spacers" and a seal for each side of the injector. I cannot seem to find what I have seen called a
"Fuel Injector Adapter" that goes between the adapter and the head. I have thoroughly confused the local auto parts stores. Is there any place that sells these by themselves?

Not sure what part you are talking about. The kit from NAPA that I listed above (ATM-IK2401) for less than two bucks each has all three seals.

If this isn't what you mean, can you show me a picture of what you mean?

So I have everything in that kit, maybe the original is melted? It is kind of "tapered" and not a fat round "o-ring" like the pieces in the kit.

Do you put the bottom rubber spacer in the head and then put in the injector, or put it on the injector and then install both at once?

Krafty,
First remove the old seals from the injectors and clean the surfaces thoroughly.

Install the insulators on the top of the injector. That's the middle part with the deep groove around the outside. This is not a seal, just an insulator/grommet for mounting.

Install the o-ring at the top of the injector in the groove. Use a little bit of gasoline to lubricate it. Obviously, be careful with open gasoline.

Make sure the old injector tip seals are out of the cylinder head. Install the new ones (bottom seal in the pbase picture) carefully into the cylinder head.

Clean the injector fuel rail mounting holes. Install the injectors into the fuel rail, using a little bit of gasoline to lubricate the o-ring. Make sure the injectors rotate smoothly in the fuel rail. Install the rail with injectors onto the head. Make sure all the injectors seat properly in the seals and that they still rotate smoothly. Install the mounting plastic spacers and the bolts.

The big-green-book has great detailed instructions on all the fuel delivery bits, with test and troubleshooting info.

Good luck.
