Fuel injectors leaking

[lebaron88]

I have just replaced my fuel injectors with some larger ones that i bought used on e-bay (from 27 to 33 lbs per hour). I have replaced the o-rings and now they are leaking (there is quite a lot of fuel under them). Could it be that the new o-rings have to swell?
Do you any any suggestions?
Thank you!!!!

Ok. I lete them rest a while and started the car again. Now they don't leak. Is it safe to drive the car? Any suggestion?

I know when I did mine a while back It was a task just to get the injectors in...then when they leaked i was ticked....come to find out if you dont get them to go in right the o-ring will break. You are probably gonna have to pull them out and check them.

Should be ok to drive just keep your eye on them....kinda silly to be wastin all that fuel nowadays....lol

Thank you: you are great!
I drove it a bit and it seems OK. Just some fumes coming from the engine, but probably it was the gasoline I spilled before. I will try again in a while.

the fuel sitting there now should dry up pretty quickly.....if you still smell it after a while make sure you check with the car running.....if you notice ANY fuel after it dries, so much as wet vapor around the injector, you may have a problem.

Do yourself a favor and pull them back out and replace the o-rings. Use a light drop of motor oil when installing them so they don't fold over or break. Think of it this way- they're leaking gas right above a friggen hot manifold/turbo. Sucks when the car burns because of some $5 o-rings!

Or have the fire dept follow you. I have also had a bad fuel injector leak. If a new set of o rings doesn't do it, one injector might be bad. Rebuilt injectors are well worth the price.

Make sure you oil the o-rings when you install them. They are not supposed to be installed dry. Mineral oil is recommended for o-rings usually, aka power steering fluid.

Ok. The car was idling rough and I got a code 26 (Injector driver circuit 1 open or shorted). I checked that the eletric connections were good, fiddling with the injectors' connections and now the rough idle is gone. However I did take another brief ride and when I stopped and open the hood there were vapors coming from the top of the engine.
Any idea?
Thank you!

The vapors seem to be coming from the fuel rubber line where it connects to the fuel rail. The fuel line was old and not particularly good looking. I will try to replace it as soon as the car cools down. Do you relieve the the fuel pressure every time you work on it?
Thank you!

[Una]

Yes, relieve the fuel pressure. Make sure the engine is cold when you do it, seems the fuel likes to boil if the engine is hot, makes it pretty much impossible to relieve the pressure.. Good way to get a face full of gas (been there, done that).

[lebaron88]

I replaced the fuel line and everything seems to be fine now: no fuel smells or vapors.
Thank you for all your help: this community is great! A big help when you don't know what to do!
