So i am helping a friend of mine restore her 1989 Chevy K5 Blazer....350 5.7L T.B.I. (Silverado Trim)
Has anyone replaced all the vacuum lines ? and where do you buy them from?
I have ordered from Rockauto ...
DELPHI DC1016 DISTRIBUTOR CAP
DELPHI DC20025 DISTRIBUTOR ROTOR
DELPHI GN10048 IGNITION COIL
ACDELCO 9618V SPARK PLUG WIRE SET (PROFESSIONAL)
MAHLE G27098 AIR CLEANER GASKET
DELPHI ES10966 OXYGEN SENSOR
DELPHI TS10075 COOLANT TEMPERATURE SENSOR
I have also already replaced all the spark plugs!
ACDELCO CR43TS..
AND THE IDLE AIR CONTROL VALVE WVE 2H1037
Getting there but it will be a long process...
any help would be appreciated!
Thanks in advance!!
here are the RPO Codes

 

There are very few vacuum hoses on an '89. You can buy the hose in bulk from any auto parts store. You'll need a couple of different sizes. Probably, your best bet would be to bring a sample of each size to the parts store so they can match it up.
