2001 Blazer 4dr RWD


I purchased the AC Delco complete Spider kit.
I want to plan some time to change it out. I am not replacing the lower intake manifold gaskets.
How many hours should it take me if I really take my time?


Any BTDT tips or other parts I should buy?


Thanks in advance

 

A hour or so. Id say no longer than 3 hours taking your time. Have a line wrench for removing fuel rail at engine/trans. Can remove whole upper intake with throttle body attached. A few sensor unplugging and thats about it. Have fun.

 

If it's anything like the spider in my '95, under an hour if you know what you're doing. First time out, probably under three hours, like TMM217 said above.

Although I would still not plan on anything the rest of the day, if your luck is anything like mine. That Murphy guy sometimes likes to show up...

 

Did it once, about 2-3 hours not knowing what I was doing

 

Thanks everyone for the information.
I think I will try to do the spider tomorrow while the weather is nice.
I will update everyone on the results.

 

Below is a link to my write up when I replaced my spider assembly last year. It has been trouble free for over a year now.

I got it finished today! Yeah!
It took me about 4 hours but I really took my time and did a few other things at the same time. Things like replace vacuum lines, PCV elbow, add dielectric grease to all the connectors, etc


Thanks for the link to your previous installation. I sure am glad that you mentioned the crows foot. I do not know how it could be done without that.
So I bought a set of metric and standard crows along with a set of shorty standard wrenches. I always keep adding to my tools when I see a future need to use something again.

The AC Delco conversion spider assembly solved the problem of excessive cranking when the engine is warm and heat soaked. Also the throttle feels more crisp.


Some things that worked for me...


INSTALLING THE UPPER INTAKE.
Instead of oil I put grease in the opening where the spider o-ring will go. It went on very easy.


RE-INSTALLING THE FUEL LINES
1. With the bracket NOT fastened I threaded the fuel lines first. I turned them by hand until I couldn't get them to go any further.
2. I then pushed the fuel lines into the spider and installed the clamp & nuts. (lightly oiled the metal tubes before installing)
3. Started the bolt into the lower intake for the line bracket and threaded it almost all the way down, but still a little loose.
4. Tighten the fuel lines by hand using the crows foot in my hand.
5. Tightened the bracket and then finished tightening the fuel line with the crows foot and ratchet.
