Don't forget to re-set your computer and make sure to lube the o-rings before installing. Pretty much every leak that happens when swapping injectors is due to one of the top o-rings getting torn or cut installing them. Check for leaks before you drive or run it long. Any other questions don't hesitate to ask.

I know I had a plugged injector but WOW!!!! First test drive was AMAZING!! super smooth idle and acceleration, power and torque were better than ever, and it started first crank! I will have to see if the pressure still leaks back, but I might not need to replace my fuel pump now!! THANK YOU!

I am selling sets of 6 cleaned tested and semi-rebuilt 784 "Neon" injectors. These are a direct swap out "upgrade" injector for 99-01 XJs and if you have an earlier (87-95) XJ I also have EV-6 to EV-1 adapters which will allow these injectors to work in place of the EV-1 703 injectors.
Basically I clean off the outsides with degreaser then take the injectors apart and let them soak a day in concentrated injector cleaner. I then reverse flush them out and then open them with a battery and visually check the spray pattern (Using compressed starting fluid). I then put them back together using new micro-filters and new o-rings on the tops and make sure there are perfect (But used) o-rings and pintle caps on the bottoms. Then I test them with an ohm meter to make sure they are within their correct range. Not quite professional rebuilding but pretty clean.
I am asking $70 a set shipped for the 784s and $80 a set for the 784s with the adapters. (A deal considering these adapters cost $25 for a set of 8 on Ebay). I also have 1 set of higher flow 715's for $70 shipped and 2 sets of the Ford "yellow stick" 710's cleaned the same way for $40 shipped. I am in Baltimore, MD and will ship by Priority Mail. Any questions at all please send me a PM. I can accept PayPal or a money order by mail.

Just got my injectors in the mail today! They look good, can't wait to get them in! Very fast shipping and the injectors are spotless.
