i pulled my fuel rail today and found that # 3 and 4 were leaking. so i swapped them with some injectors from another car, which dont leak. but when i put them on my car they leak. whats the problem here? my harness? LMK (86 daytona TII)
thanks

It might be time for some new O-rings. It is a very noticable differnece between the old ones that are probably on there and the new ones when you look at them side by side.
i thought of that but how would that make my injectors leak. i pulled the rail left on the valve cover then primed the pump, after 10 minutes you can see fuel gathering up.

you have to remember your ring are most likely 10, 15, or 20 years old and if im right all they are is rubber
The best and cheapest place to buy new O-Rings is at NAPA. the part number is #2-12093. They come in a small box with two o-rings per box. I paid like $10.00 for all eight, but you should consider replacing the oring on the fuel pressure regulator as well.

OK. but can some PLEASE tell me how that would make fuel leak from the nozzle (whatever you call that). you sit there and watch it puddle up.
and i doubt the o rings were all bad on all of those other injectors that dont on another car
When you pulled off the original FI you more than likely tore a smll piece of the o-rings. It happens all the time if the o-rings are old.Originally Posted by TurboXT

OMG. its not the o rings. do you guys even understand what im saying????? its from where the fuel comes out. tell how an o ring would cause that
its almost like something is keeping them a lil open. i tried 4 other injectors and they only leak on # 3 & 4
Then there is a grounding problem Gabe. They aren't listening to what you are saying, the only way the injectors will stay open is if there is a ground issue, so try grounding out both sides of the rail
finally a good answer. thanks man. maybe the ground from the harness is bad? i'll swap w/ my shelby
Make a new one out of some 8 gauge speakerwire, the stock braided grounds are crappy
Then write your problem clearer. You said they were puddling, nothing about it coming out of the nozzles. Don't get mad at us for throwing out ideas.Originally Posted by TurboXT

He clearly stated that it was coming out of the nossle and that he swapped the injectors only to find the two in the 3 & 4 spot were leaking no matter which injectors are in there, which leads me to believe a grounding/wiring issue as if the injectors don't leak in another setup then they aren't dirty

Well how come when he changes the injectors to ones that don't leak, they only leak out of the #3 and #4 spot?
That is weird but trust me, if the injectors are energized, they won't be trickling out,Originally Posted by Garret

For that matter, there's a fine way to test for that. Just put fuel pressure to them without hooking them up electrically. If they still leak, then it's the injectors. If they don't then it has to be some other issue.
Tony that's a good suggestion
Its rare, but I've seen it happen.Originally Posted by turbovanman
Last fall at my shop while I was trying to get my car up and going, everything was done, everything was in place...
"Fire in the Hole!"
"WTF? Damn!"
A quick 5 min drive to my house for my spair fuel rail/ injectors and all was well.
But back on topic, its probably the O-rings.
