Hi there,

Well I’m at the pointy end of getting the the Olds going and just struck a problem re the carb hoses.
My photos from eight years ago when I removed the Quadrajet to put a Holley on are on a hard drive we can no longer access.
My manual does not help me nor does Google.

I have ports on the carb that I cannot remember where they go to so any answers diagrams (mud maps appreciated) photos etc will be greatly appreciated.

Also:
1/ On my photos the screw driver indicates the port I need info on where that goes to.
2/ Where does the choke connect to?
3/ where does the Throttle Return go to and do I really need this?

Thank you.

 

#1. Tee brass fitting - the straight larger hose goes to power brake booster. The smaller goes to the fitting on top of the fuel pump.
#2. A solid tube goes directly into the manifold (presses right in).
#3. A short piece of vac line connects to a brass tee, another short piece of vac line connects to the tee and then to solid line of throttle check return and then a long vac line connects to the tee and then to the vacuum advance on distributer.
#4. A vac line goes from the other fitting on top of the fuel pump to (for mine it goes to the deluxe heater inside the dash, I used a red tube).

 

I f you are calling the carb in these pictures a Quadrajet, thats a mistake. You have a typical Rochester 4GC. I would think your 1959 Olds CSM should show the vacuum lines, choke and anything else.

 

Thank you Supernice 88.
I’ve got that done now with your help.

 

Is that Detroit diesel green on your engine?

 

You're welcome.
Your engine and bay looks great. Looks like you'll be cruising soon.

 

I just asked for “original factory colour” not sure if it is or not.
I have a pic of my new engine and my old engine cover to compare mind you the old engine covers not sure which one is closest to factory.
