SOURCE: Need vacuum diagram

I can't send you a diagram but I can tell you the basics that should get you mobile. Take a vacuum line from the lower front of your carb and hook it to your distributer vacuum advance. Take another from the front of your carb and run it to your EGR valve. It should be beside the carb on the intake manifold. At the rear of your carburator there is a large line coming out. It should be steel. It provides vacuum boost to your power brakes. Hook it up. Make sure all other vacuum outlets on the carb and intake are blocked off and you should be able to get mobile.

1985 chevy c20 vacuum problems


on this truck the vacuum is pretty basic, im guessing you have a 305 (5.0) or a 350 (5.7), on the front of the engine compartment near the fan shroud somewhere (if it is still intact) you should have a diagram of all the vac lines
you probably have a quadrajet carb, if you are mechanical and patient they are not hard to rebuild

blowing out the carb with carb and choke cleaner isnt a bad idea either, have someone keep it running and slowly run like 1/4 to 1/2 a can down the carb spraying all around

Do you know where i can find a 'vacuum diagram' for a turbo 350 transmission (1980 chevy blazer...stalls when you put it in gear)


There is usually only one vacuum connection on a turbo 350. It connects to the modulator valve on the side of the transmission. This valve uses engine vacuum to determine transmission shift points. The other end usually connects to a direct engine vacuum source. A "direct source" is a hose connection on the throttle body that has a vacuum signal available at idle. If it doesn't, then it's considered a "ported source".I have had some experience with the chevy blazer/gmc jimmy series, both the early large body models and the small body versions. The stalling when put into gear complaint is most likely caused by a bad intake gasket which is common on the older versions with the small block V8 motors. The newer versions with the vortek motors also had allot of trouble with throttle body gaskets. If these problems have not already been addressed, then there's a good chance that it will take care of the problem. Other possible sources of vacuum leaks are the pcv hose that is hard and brittle. Check the hose out carefully, especially the side that normally faces the engine. Check the throttle body bolts (carburetor bolts) for tightness. I hope that this information is helpful to you. Thank you for using Fixya.com.

WHEN I TURN THE ENGINE OFF AFTER I HAVE RAN THE TRUCK IT BACK FIRES THIS IS A1985 CHEVROLET PICKUP 3\4 TON SCOOTSDALE WITH A 350


Check idle speed and mixture at idle. Often with too fast idle speed, engine will not shut off. Many vehicles had an electric solenoind that released the idle speed to much lower, at key off.

Vaccum hose diagram for 88 chevy truck. I put a 350 motor in my 88 chevy 1500 truck from a 95 suburban. I cant get the throttle body to stop idaling to high. I may need a vaccum line diagram for this motor...


it may not be a vacumn leak from a line,check the throttle shaft for movement,for example,i had a 89 1 ton 350 and my throttle shaft was moving around a lot and in order to keep it from idling high,i had to kick the throttle pedal.But also check the idle air control valve,which is the round sensor on the side of the throttle body.
