Replacing Injector O rings...mandatory?

[EsChassisLove]

I just popped these injectors in about 2 months ago. Put maybe 500 miles on the car.

Anyways i have a new fuel rail and FPR to put on but I spaced on ordering O rings. Don't wanna wait till Tuesday to get them.

Think i can get away with these rings?

How do they look? If they look dried out, they're waiting to crack. I put ones in that i thought looked fine, ended up spewing white smoke because fuel was pissing into the cyl.

When you swapped injectors 2 months ago, these were fresh o-rings right? if they are, yes, reuse them. If they're still the same original o-rings that you reused before, then, I'd be iffy.

Yea they are fresh rings.

should be ok...just be carful puttin em in. if you pinch a ring on the install you will leak fuel everywere..lol. ask me how i know..

As long as you didn't damage them when taking them out

If they're the least bit questionable I would just replace them. Almost set my Mazda on fire once because of a shitty O-ring. Puddles of gas on your motor are no bueno.

So i didn't replace them. They sealed up great, no leaks.

But the fat O rings that are on the intake manifold....those are a diffeRent story. Rail wouldn't bolt down enough to seal up with it. So i improvised with some old O rings

Sealed up great.

is that an aftermarket side feed rail?

Yes. It's the circuit sports rail. Got a Damn good deal on it, and my stock rail was bent so I couldn't pass it up
