I'm having a problem with my 703 injectors I purchased for my 91 Cherokee. I couldn't get them to seat in my motor or the furl rail. I called a friend over so I could try 'equalizing' the pressure while feeling for them to lock in. If you see the picture the black one is the 703 but the end shown that goes into the motor is too long for it to let the o ring go deep enough to seat. Same on the other end. Am I missing something or.....

 

there are plastic bushings missing from the ends

 

Looks like the right one,maybe there is some crud built up in the hole?I had to clean mine out with a little dental pick like thing....Is it a Renix?

 

did you lube the o rings with any thing

 

I did clean out the holes, also used a nice blob of vasoline on both ends. I'm not sure of the brand, here is a photo of the entire injector. Because This new project is my d.d. I slapped the old factory ones back in today without a problem. I hadn't heard of swapping injectors till I joined This forum and was excited to try. Any tips?

 

And I bought these from another member of the forum. I do not think I got taken I think I'm missing a step on the installation?

 

note o ring location and little bushing

 

There ya go!!!!I feel dumb for not seeing that....Also no pintle caps either.good eye Freegdr

 

Is that a #739 im seeing on those injectors? If so, I believe they be wrong.

 

There it is. The o-ring is set to low. it goes directly below the pintle cap. They take a little work to get into the fuel rail, but that's what the vasoline is for. You didn't miss a step in the install, just a simple mistake in "construction".

 

i saw that also but the other side says 703

 

Think You feel dumb try being the guy that started the thread :-). Thank you everyone, try again next Saturday!

 

things like this is what every bodys here to do look at things a different way ....just dont do any thing this lame again... putting your rubber on wrong can really mess things up....lol

 

I wear mine inside out

 

This was the best laugh of the day for me. THANKS!!!!
