Edit:

I dont see this as a problem unless it's not running right. If you have a lack of power anywhere through the throttle or if you start misfiring, then i'd look into it. Also if your mpg drops drastically

No its not a problem at all. Everythings fine. I was just wondering if anyone else had this happen to them when they did the swap

What's up with neon injectors? I have seen them brought up. What do they do? What year are they from? ...... Write up somewhere?

There's a write up somewhere on here about them. The general idea behind it is this...

better atomization of the fuel due to 4 holes instead of 1

This then gives a more consistant burn, a more complete burn, can cause more power, and increase mpg.

I have to say i was kinda 'EH' about doing thing project..and now that ive done it I wish i would have done it a long time ago!
703 are for xjs up to 97
784s are for xjs 99+
*98's are a mix you gotta look at your plug to figure it out.

All I did to release the pressure in the fuel rail is, while the jeep is running, pull the fuel pump relay. Then let it run outta gas. Now, that still left some pressure, not much, in the lines so I just put a rag around the fuel line as I disconnected it from the fuel rail.

Wow thats so much work. Just take the gas cap off use the pressure releaf valve. then disconnected the fuel line and pop the injectors out of the block with them still on the rail. so much easier.. and didnt really even spill any gas. but you could do it that way..i guess to each his own

You don't even have to take the gas cap off, just depress the valve at the test port.

@ Polar, same flow rate as stock.

Well I just did it just cause lol but with it running, I depressed the valve and I was suprised at the amount of air that came out of the fuel rail
