My injectors are #0 280155 740. I feel like I have the wrong injectors.

correct number is 703 on the end. You need to replace the baskets too. Put a screw in a vice and screw the part of the injector where the basket is onto the screw. Now with a rag hold onto the injector tightly and firmly pull. If you did it right the basket will be on the end of the screw. http://www.jeepforum.com/forum/f13/o...ctors-1403478/

From looking at pictures, the 0280155740s may be a short-body injector and thus cannot be used with an unmodified ZJ fuel rail. I found a lot of Neons with those when I was looking for the 703s. I found 703s to be more common in the Cirrus and Stratus.

I just got my injectors from two 96 Dodge Neons from the Junk Yard. 5 bucks each for all eight. Just got the O ring replacement kit from Barclaycard as recommended in the first post.

They are the Bosh 703 injectors. I will be doing this upgrade along with fixing the plenum chamber next week.

Remember to take the connector(s) from the donor car so you can pulse the injectors to help clean them and make sure they function.

Don't forget to lube up the new o rings with some vaseline before putting them on.

I own a 1995 ZJ Grand Cherokee Laredo 4.0, I followed this forum in replacing my injectors. I replaced my stock injectors with the Bosch 0280155703 approximately 5 months ago. I have had nothing but positive results. From the first time I started the engine the jeep idled much more smoothly. The response when stepping on the gas seemed quicker. The best result has been in MPG. I went from approximately 17 mpg to 19 mpg.

I am currently re-reading through the forum because I want to try the same thing on my 1996 Dodge 5.9. If I decide to do this I will also post those results.

I wouldn't do that on the Dodge if I were you. There are some pretty negative posts earlier in this thread from a member doing this on his Dodge. The computers are different and it won't properly handle a 703 injector. Also, the overhead is slightly off, by about 2 mpg, when you go to 703s. My hand calculations stayed about the same. The only thing I've noticed with mine is a smoother idle.

So if the overhead is off by 2 then that means if I was averaging 17 mpg and it now shows 19 mpg's it is off. It still increased so I am counting it as a gain even if I have not hand calculated the mpg yet. With the Dodge thing I have seen the posts. If I cannot find enough people with positive results I will not do it. I have checked the Dodge forums and have found people who have bought stock replacements 4 hole injectors over the single hole. I was just trying to save $$$. With the swap in the jeep my wife likes driving it a lot better now than before.

Ive searched the internet all over and cant find a definitive list and the OP on this thread only has the donor vehicles for the 703's and the 715's... so my question is does anyone have an accurate list of donor vehicles for the 710's. I have six sitting here waiting to get put in my 94 5.2, lol i ordered eight but only got six so i need to procure the other two myself and dont know exactly where to get them from at the junkyard.

I have done some research on this because I recently got the P0301 code on my 2000 Grand Cherokee. I don't know if this is what y'all are looking for but it might help (hope it does).
