well it depends..usually if you have a 4brl carb the vacuum is built in the carb.
the intake manifold is the main source of vacum. from the carb mounted on the manifold. if you have a 2brl and want to switch to a 4brl, you have to get a new manafold that is made for a 4brl carb..it might be worth your while to do this..it elimates all the hoses and clutter junk from a 2brl.
if you have a 2brl, it can be a little complicated. the vac on a 2brl is threw the air cleaner unit. theres vacum hoses that conect to the rear of the carb. the EGR valve a round like cilinder on left side of intake manifold. the choke mounted on the side of carb, and the thermostat housing.
...good luck
The vacuum hoses are very important in a 1991 Beretta. Without the vacuum lines, the engine will not run properly, and the power brakes will not function.
that must be some metro to have a big block
I need a lay out of all the vacuum lines for a 1991 Chevy van.
That year transmission did not use 1
It is under the battery rack. Remove the battery and there are three bolts in the engine bay and one in the fender well.
A 1991 Chevy Van has a 4 speed automatic transmission. The engine on the 1991 Chevy Van is a 4.3 L V6 and a 6.2 L Diesel engine is also available as an option.
I need a diagram for the 1991 Chevy blazer to see where the 3 hoses go to coming off the transfer case.
yes
yes you can
Not Enough
YES it will fit right in, with a few mods. But it will never run. That engine requires an electric fuel pump and a computer system.
Start at vacuum source at engine and follow line-by-line
