Stock SS injector part number?

Est98SS · 06-29-2018, 04:43 PM

I need to replace an injector and I’ve been calling a couple chevy dealerships and giving them my vin and all of them are saying 3 options for the injector pops up, low flow, nominal flow, and high flow. Does anyone know which ones our cars use stock?

Why not pull the injector and use the part # on it? GM has 3 different injectors, I had one replaced in my 2016 Sierra 6.2L and the tech said the same thing about the 3 different injectors.

Sadly 2 of them are on 3k+ unit back orders right now.

You have to replace with the same part number as they are flow matched for each bank on the engine.

You will also need to replace and size the seals on the other three injectors. And finally, make sure you replace all the high pressure pipes as well and torque them on reassembly.

Good luck!

Do those high pressure pipes really need to be replaced?

Also, whats the tq spec for them?

I did not replace the fuel lines when upgrading to LT4 injectors and HPFP. the torque for the fuel pipe nuts I believe is 22 ft/lbs per this chart: https://www.corvetteforum.com/forums...ue-values.html

I was able to get a verbal verification that some of the shops on this baord do not replace the lines, they clean and properly torque the nuts. hope this helps. I have not had any fuel line leak issues to date.
