My spider injector in my 93 S-10 Blazer is leaking out the top, and I can’t find a rebuild kit. Does anyone know where to find the whole spider as a unit? Everywhere I’ve looked is out of stock. Or is there an upgraded type injector for the first gens?

 

Not sure, but is the right repair kit for your engine?

That kit is not for CPI, it's for TBI. Spider injectors are CPI units.

I have not found a source for complete CPI injectors, other than ebay. You can buy a remanufactured one here:

GB REMANUFACTURING 83322101

(They only have 1 in stock, so if interested you might want to act pretty quick)

 

Good catch, white94. Thanks for correcting that.

 

for some reason the blazer is the weird one. but im gonna help you out on this one.
go to a junkyard and find a same year chevy astro with a 4.3 and they will have a CPI system in them and while it sucks to pull there is alot more of those around and they usually work. also ive rebuilt ~5 of these systems and can tell you they are the exact same and the o-rings are just standard nitrile rings and please be careful these units enjoy shattering nowadays

 

I bought a new spider unit from Rock Auto .com about 5 yrs ago and still works great.My blazer is a 1993,
Vin W.I also bought a new CPI and harness when I replaced the Spider

 

Did you end up finding one? In the same position in 2025 they are hard to find!
