703 Injectors Installation
So I have my injectors ready to go in, but I was wondering two things.
Do I reuse the O-rings on my current injectors for these? I had a buddy get me a set from the junk yard and soaked them, but I'm wondering if I need anything else.
Also, I saw in a tutorial thread, that you have to be careful of the dirt/grime falling into the injector slot, and that's is pretty bad if it happens.. Is there a way to avoid that? Can I thoroughly clean the area before swapping or anything?
Cheers

Get new O rings. Can never be too careful with them. It is gasoline we're talking here. Any risk of going up in flames is bad.
As far as dirt falling in the holes... Take out the old injectors and then get to cleaning. What works is using a flathead screw driver and slowly and carefully scraping crap out of the edges of the holes.

if you have a extra hour take your intake manifold off, you would not believe the char and gunk built up and give it a good scrubbing, and also clean injector seats, if your having issues installing new injectors/o rings dab just a tiny bit of motor oil on the o rings prior to install.

I used throttle body cleaner and dipped q tips in it and cleaned the injector seats. The throttle body cleaner break down the grime and the q tips soaked them up.
You probably would use up like 100 of them so buy a box of it, get good quality brand not cheap ones cause there isn't enough cotton on tips.
Like 4 bucks

If you're going to be doing your manifold, then definitely do the injectors at the same time. You'll be able to scrub the crap out of the intake manifold and injector seats with not a worry in the world because you'll have it off the motor. That's what I'd do
