I read that it replaces the original one.

Unfortunatly the other order was already placed/sent....to I'll have to send it back when I receive it Tuesday.

On the bright side, I can put everything back together tonight/tomorrow!

replaced it with the new assembly. its amazing...but GM didnt list that part number in there computer system to come up when you search for the spider assembly for my vehicle. here's what I think happenend. GM realized the original injector system was a POS. They frequently got stuck either open or closed......surprisingly, even though so many different years and models used this system, they never recalled it...but came up with this NEW injector system.

Sooooo........

They stopped making/selling the old system as a whole...but instead continue to sell the individual injectors for it. So if you have a single bad injector on the original system, you can replace it for about $100.
What's so odd though...is that you can order this NEW IMPROVED spider assembly as a whole, for under $300 with the regulator included. I told the dealer they should make a note of that......because until I gave them (and other dealers) the exact part number for the new spider assembly, they had no full assembly available for my vehicle....only single injectors. Don't know if its an intentional mistake by GM to rape customers at $100 per injector, or if its just a screw up in the way their listing is.

Thanks to Blazee for the info!

Here's the part numbers:
12568332 - MFI Assembly
88894355 - Bracket
17113215 - Seal kit

But, the bottom line is, I bought the new fuel spider. The gasket kit, I'd already purchased when I was trouble shooting...it includes the gasket for the throttle body, the gasket for the upper intake cover, and the gasket for the fuel spider where it seals inside the cover (seen in orange below).
The bracket IS different from the original, and although it appeared to be similar enough to use the original, its not. The NEW injector lines are thicker then the originals, and the bracket needs more clearance for them all to fit in. Once all the injectors are inserted, they put slight pressure on the fuel spider in the direction of the firewall...which keeps the bracket seated firmly.



Cross your fingers that this takes care of my horrible MPG...unless my gauge is wrong, my pressure is still only 54psi after the new fuel pump, fuel filter, fuel line o-rings, and new spider assembly/regulator. Go figure~!

You need to pull the valve cover and recover it. Or use a magnet and fish around. You really don't want it in there.

Oh, and where you posted. This thread is 7yrs old.
