Fuel Injector issue on Gen1

Gas is leaking a little on the brown top engine - but car runs fine.

Parts seems not that easy to comeby - which one is the correct part # for 1987 Acura Integra 5 Door LS Auto:
https://www.acurapartswarehouse.com/oem ... 7-661.html
or
https://www.acurapartswarehouse.com/oem ... 7-662.html


Is there a workaround to fix the issue without replacing the unit. I see refurbished units on eBay - changing the o-rings is not going to fix the issue, right?

I once bought a clip on eBay with OEM packaging - it must have been a fake - had to buy it again from dealer.

16450-PG7-661 is the correct part number for your application (the whole injector)

If you have a faulty o-ring that is causing the leak, then yes, you can just replace the o-ring. Again, this is only if the o-ring is leaking/cracked/defective.

If you're just replacing the o-ring, then you'll want:

16472-P10-A01 - O-Ring

AND

16473-P10-A01 - Cushion Ring (injector seat)

@jjkz24 - thanks indeed

So what is really the different between the 16450-PG7-661 & 16450-PG7-662?
And I need to buy 4 of these? When I buy them, do they come with the o-rings?

I found I had to change most of the o-rings, seals etc - is there a way to figure whether o-ring is bad or not?

How many of these o-rings and cushion rings do I need for each injector?

The difference between both part numbers, is that one supersedes the other. Acura/Honda updated it. The old part number is no longer used

Are all four injectors leaking? If all four are leaking/faulty, then yes, you replace all of them. If only one is leaking, then you replace one of them. If two are leaking, you'd replace two of them. (see the pattern here?)

Yes, if the o-ring is cracked, warped, torn, or otherwise not perfect, then it's bad.

You have four injectors. You'll need four o-rings, and four cushion seats. (again, only if you're replacing all of them)

If you look at this picture, 21, 5 & 4 - that is why I thought there might 2 o-rings and one Cushion Ring per injector.
https://www.acurapartswarehouse.com/...0-pg7-661.html

On top of the brown engine cover, there is gas near all 4 of them all 4 must be leaking

Update:
With faulty FI, someone's Integra acted weirdly at good speed - mine is smooth - possible o-rings?

#21 is nothing for your specific model

#4 is your o-ring

#5 is your cushion ring

So if I buy the FI at RockAuto (link below), I need to buy the o-ring and cushion ring separately - no one sells them together - is there a cheaper place than RockAuto?
More Information for STANDARD MOTOR PRODUCTS FJ267

The o-ring etc, if I search on RockAuto, it comes in multiples of different size in one packet - you still need to buy 4 of these?

Those are really good prices. Do you really want to cheap out on purchasing something as vital as a fuel injector. If you want cheaper, purchase remanufactured units, or find used.

I am not familiar with the brands listed for your o-rings with the link that you provided. I'm only familiar with parts such as OEM from Honda/Acura that I KNOW will fit. You'll need to contact the manufacture of the o-rings that you're looking to purchase, for details on what sizes come with each package.

Thanks @jjkz24

Is there a DIY video to change the FI on the gen1? I did not have good luck.

Found instructions below for 3rd gen:
Fuel Injector Leak

Video on 2nd gen:

I checked online prices at Curry Acura and Delray - Delray shipping is lower at Delray comes to (4 x O & Cusion rings):
  • Subtotal Amount: $59.16
  • Estimated Shipping : $6.40
Is this how much you spend?

In this picture (fit for my car), O-ring and Cushion rings are on the same side:
Advance Auto Parts - Down for Maintenance

But here, they seems opposite side:
https://www.acurapartswarehouse.com/...0-pg7-661.html

I just do not want to start working on the car without the right parts - so I am wondering on these discrepancies - besides there is a 3rd black gasket on the tail end of the FI?

This one seems to have 3 too:

I cannot comment or give any advice on aftermarket parts. Manufacturers of aftermarket parts might include or display their products differently from one another. The best advice I can give you is to contact the manufacture, and ask them directly. For me personally, I ONLY use OEM parts for my Integra because I know that the quality is superb, and that I will not have any issues with fitment.

I can only give advice for OEM Honda/Acura parts because I used to work at a Honda/Acura dealership for many years. I know that OEM parts fit precisely, and what parts do and don't come with one another.

Replacement is pretty straight forward. If you watched other videos and looked at other threads, then you'll have a general idea on how to remove & replace. They're really easy.

I'm not sure what your last question is asking, when you say, "Is this how much you spend?" Price will differ between manufactures, and online retailers.

It turned out #21 is relevant - and most important - prevent leaks and most expensive.

I bought and changed them all 3 in each 4 - the leak stopped.
