replacing injectors got a question?

[totaledXJ]

3 of my injectors on my '89 4.0 started leaking this weekend. I picked up a set of 19lb 5.0 injectors from a friend of mine who pulled them out of his Mustang to replace with bigger ones. My question is can I just replace the 3 that are leaking or should I replace all 6? I don't not what the stock ones are rated at so I'm not sure if they can be used together with the 5.0 injectors or if I have to use one or the other?

Thanks, Kevin

so is the cheapest source for replacements 5.0 injectors? I had one go bad last year and had to pay 80 for it. I want to do the rest now cause its having symptoms again.

Yes, I agree, who has the best prices on the 5.0 injectors and if someone has them, the part numbers. I have no clue about buying them and when I looked at that 5.0 site they had like 4 or 6 different models. Is it just a case of 'match the connectors' or what ??? If I call them up and ask for the '5.0 injectors for a 98 Cherokee 4.0' will they know which ones I'm talking about from selling them to others ???

dont want to sound like an ass, but try a quick search...

I am currently doing the same project right now. 5.0's are direct swaps for the factory injectors. I would not only swap 3 because the 5.0 injectors flow slightly differently then the factory units and this may result in a few cyl getting more fuel or better atomized fuel.

As for the cheapest place. www.fiveomotorsport.com . Bruce is the man. He has helped me on my problems i've had with my used injectors I bought off of him. How many companies will you find that will awnser an technical email at 6pm on a sunday afternoon??

I just did that swap in my 89. I got then injectors out of an unmolested 4.0 Explorer at U-Pull It. The six of them cost me $30 and it works great!

Make sure you replace the o-rings on the injectors. You can get them at napa or others I'm sure for a little $. Cheap insurance is good

Thanks for the input. I went ahead and replaced all 6 since they were Freebees. I also installed new o-rings - Kevin
