What am I going to gain if I purchase the new ones vs. the ones the JF vendor is selling as rebuilt/re-newed???? IF they have new screens, rings, lintel....isn't that essentially a new injector? Cause $10ea is sounding too good to pass up vs. $25 ea.

Im in the same bout as you are, youre getting new plastic thats it IMO...maybe some piece of mind that its new...IF it was coming from a walk in business, the whole ebay thing has never sat to well with me with impression of quality goods for cheap...because in all reaity 25 dollars is super cheap than what advanced auto sells these puppies new for, the sell them for like 150 a piece... makes me wonder how "new" his are as well...

At any rate mine have been in my jeep since 1994 they work just fine, im sure newer injectors used, cleaned, with important components replaced new will work just fine.

ok so all went well with all the help from my gf and everyone on here and my trusty service manual.

My gf loves taking pictures so i have included some that she took

The hardest part was the driver side font two wouldn't hardly get out or go back in the rest was a cake walk



turning the injector makes it a lot easier to take off the clip



the comparison between the new and old injectors



my service manual said to oil the o-ring with some engine oil and boy did that make things easier





having it backwards to put the clip on makes thing easier also



and there we have it they are on when i turned the key to the on spot and waited about 45 seconds then off and on few more times then stared it and it and she ran really rough for the first few seconds and then started running smoother and now she runs great idles smother and throttle responds way better so i can confirm it works on a 98 jeep grand cherokee 5.2 v8

In the classified section....6 remans for $55. So I guess that's a little less than $10 ea

When changing the injectors to 703's or as I my case 710's do I need to be concerned to altering spark plug gap or any other electrical/spark/ignition timing issue.

You think it would need adjustment really, everything is so precisely designed and timing is important, I know we're not changing the fuel amount too much just spray pattern but I would think that would affect timing of the spark and combustion etc...

ok, i went to the junkyard today and found some 710 injectors to try out this swap to see what all the fuss is about. to answer dpshoup's question it's a 8mm deep socket. and bring a flat screwdriver with you. that's all you need. I was luckey enough to find a set of 710 injectors that look practicly bran new. when i pulled them out they where like super clean. when i got back home i switched them out, turned the key on and off a couple times and left the key on and then went to check to see if there was any fuel leaks. all was good so i started it up and started a litttle rough then smoothed out. like really smooth out. this is the smoothest idle i have very seen/heard from this jeep. i let it idle for about 15 minutes and while it was idling i was still looking for any fuel leaks. still couldn't see any. i guess it is good thing. after that i shut it off restarted and took it for a spin. i can report that it has better thottle response and as for any increase i gas mileage it is to early to tell. i will report back in a couple days of driving. the one thing i think that is lacking so far in this thread is a vehicle list for the 710 injectors. i totally forgot which vehicle it was that i got mine from other then it like a grand marqui or lincoln ....something like that the year was like around 96 or maybe 97. if some can chim in and maybe provide a list i think that would greatly help this thread and all the guy's and gals out there with the 5.2 that want to try the 710's out. thanks again for this thread. other then the lacking info on the 710's it was a weath of info.

I did this swap just before I retired, so I'm not driving as much as I was, put still drive in the area. Driving up the mountain and going to work, my average MPG always showed 15.6 or 15.7. The trip home always showed 16.6 or .7. My over all average was 16.7.

The five days I drove to work after the swap it never went below 16.3, And the trip home showed 17. or 4 or 3. The first tank showed 17.3 and the second tank showed 17.4. So my net gain so far is between .6 and .7 MPG.
