i just picked up a 99+ intake that has aprox 40K miles on it and i plan on putting it on my 96 with 165K miles. the 99 has the fuel rail on it and i was wondering, can i use that fuel rail instead of using the one on my 96? is there a differed sensor or something between these 2???

its best to stick with your 96 injectors and fuel rail.

The 99 injectors have a little lower flow, and different harness connections. It's also got what I believe is a regulator on the rail, and I was concerned about that messing with my fuel pressure/flow.

Ah, here's the thread. Hope this helps, at least with regards to the injectors.

X?--stick with the 96 injectors(23.2#vs 22.5#), unless you feel like soldering in the newer connectors. So I guess I don't need to yank one for you at the JY. I went a week or so ago to get an ecu--98 was the only newer body style there so no manifolds.

one for a 96, and you don't need an injector tool, just new rings and some vaseline. You might use this time to buy some carb cleaner(3-4 cans) and a tooth brush to clean out the port areas that you can get too with manifolds removed.

what about the carb cleaner that goes into the motor? do i just leave it in there?

i have read people blow it out with a compressor but i do not have one.
