If you are thinking about doing this upgrade, get off the fence and get these injectors from this member. You will not be disappointed. I bought from him a few months back and just got around to installing these yesterday and I can already tell there is a positive difference. The seller is a pleasure to do business with.

Glad you are happy with the swap. |

Are any of these appropriate for my '89 Renix 4.0?

Yes sir, the 703's will work.

One of the easiest modifications on our beloved 4.0’s is a fuel injector swap. For some, this may sound like a technical and daunting task, but rest assured, it’s actually quite simple. The reason for this swap is simple. Jeep used 1-hole pintles on their injectors while Chrysler used 4-hole pintles on the rest of their products. The 4-hole pintle allows for a more even fuel spray pattern, resulting in better atomization, making the engine work less and run a little smoother. The results you gain from this are a smoother idle and better throttle response. Some have seen a very mild gas-mileage gain, but this is due to running clean injectors as compared to the stock ones that are dirty.
Take from here because it is a great explanation. https://thexjguys.wordpress.com/2012...injector-swap/ |
Interested. I'll double check mine to confirm they are the original stock injectors. If so I'll likely order a set. Thanks.

Couple of sets of 784's and one set of 700/710.
$70 - 784 shipped, $60 - 700/710 shipped. https://cimg9.ibsrv.net/gimg/www.che...3d8e363065.jpg |
703's arrived today via USPS. I'll try to install them tomorrow.
Well packaged, good looking injectors and a very straight forward transaction with no hiccups. Top marks to the seller. |
Thanks Jimbo!
|
703's make a renix run rich. Renix want 746.
|
Don't think twice about getting a set from Jeff. I got a set a month ago and it gave me a huge MPG improvement.
|
Got mine today, they look great! Well packaged and shipped fast! Cant wait to put them in, thanks jhc
