Fuel Injector O-rings

09-01-2023, 06:46 PM

I have noticed some slight "wetness" around my fuel injectors. Been thinking of replacing them since they're quite old now.

Prices vary greatly on FCP and I am not sure if the top and bottom are different sizes.

I've used kits from InjectorShop before with success, and I found this generic kit that I think is the right size? https://theinjectorshop.com/products...42f090a0&_ss=r

Can anyone confirm?

The uppers and lowers are different. Realoem gives the sizes.
