While it doesn;t hurt to install them before hand I feel that if stuff is done properly it can all be done at once. You just have to cross all the t's and dot all the i's.
You should have two different o rings on the injector. The lower ones are what you are supposed to replace with any install and removal. They should sit in a small indent just above the pinsle cap (plastic cap). If your injectors are suspect all together you can always send them to RC engineering where they are cleaned, flow tested and the o-rings and pinsel caps are replaced. I did that with mine before I ever installed them.

whoa whoa whoa...the very tip of my injectors are bare metal...no plastic tip...my stock ones came with that little orange cap on the ends of them, but the 370's didnt...is that ok???

the injectors can still run without the pintel caps, I'm not quite sure what they do... although just by looking they do keep the oring from slipping off...

well what do you think i should do about the bottom o ring coming off, because im sure that was my problem...they were all pressed against the platic peice when i put them on...which is about 1/4" away from where they were suppose to by...what do you guys recommend about keeping the o-rings in that small ass indent? maybe a small dab of liquid adhesive in the indent?

I think you should get someone that knows what they're doing to help you... I'm not trying to be an ass but you're making one mistake after another.
i agree..i would love some help...but people around here dont offer any help for free...so i am just gonna have to take my time and do it right by myself...and leave all my questions that i have to you guys....hopefully...i want help, but cant seem to get any thats free...someone whose only gratification is knowing that they helped another car guy out...but not around here

Do you have a FSM? I think you should invest in one as the mistakes you make can quickly add up to equal the cost of buying one anyways! The FSM should clear up a lot of your questions...
BTW... don't use adhesive on the injector orings...

yea im using the fsm...but i didnt look at it for my injecotr problems...i kinda panicked and came straight to you guys haha...yea...im gonna study this thing

oh, and i know i have to buy a new throttle body gasket, because its made of a paper like material...but do i need to buy a new intake manifold gaSket? its metal, so cant it be re-used?

Yes they do keep the o-ring from slipping off. The fuel pressure will be enought to push them down and eventually you'll be leaking gas like there's not tomorrow. That's what happend to me last September. Result the engine was toast, I have bent a connecting rod. I had to replace my engine. If you don't have the plastic cap make sure you get injectors with them on.
well i just called nissan and the guy said that he doesnt know what the pintel cap is...so he looked at a diagram of the injecotr and told me that they do not come seperately...i guess ill have to call rc engineering and see if they have any that will fit?

ok..i shipped them out already to RC...where they will put new o-rings and pentil caps on... they will be back here in 5 days...and ince i have to wait for my fmic anyways, i might as well...thanks guys
