Hi, I have corolla xl 1993 with 2e engine.can descrip carburator nipple (vacuum and others) with image. So thanks.

EGR is on passenger side of engine at the end of the intake manifold, It should be a ROUND vacuum actuator being held on with 2-12mm nuts.

How old is this Carb. 1b, 2b, or 4b? Look around the base where it bolts to the intake manifold and there should be a nipple with a tiny needle size hole, there maybe several & check all sides. Check the manifold as well. We used to cap these off to isolate a problem with the engine by using a short piece of rubber tubing with a sheet metal screw stuck in the end. There are ways to search for a vacuum leak with engine running and wd40....it will temporarily block the leak or be consumed and the engine will speed up,,, but you must be careful, safety first..

Standing in front of the car, the lower left vacuum port on the carb goes to the distributor. The upper left port goes to the vacuum switch for the secondaries. The brake booster screws into the rear base of the carburator. The transmission kickdown plugs into a nipple on the rear of the intake manifold.

Hope this helps...

Hi there:

the part house will have one all day even if they have to order it

It is similar to my rear wheel drive two door.

The main vacuum line from a vacuum source on the intake goes to the multi-hose valve on the top and the distributor vacuum advance.This multi-valve switching valve is the main connection to the other vacuum hoses on mine. Two lines come in from a vacuum source and thre go out to three components according to tempature. On mine the middle one off to side 1)goes to choke opener and switching vacumm valves mounted on the fenders the other middle one 2)second from top goes to another choke opener and EGR Valve and EGRModulator. The bottom hose connection is on when cold 3)and goes to a part on the carburator to help it run better when warming up a AAP valve.

There is a check valve diaprham thing inline to the EGR vlave on the second line from top.

I have another vacuum line on the drivers side of the carburator that has a check vlave inline but larger it goes to the throttle linkage to help slow the closing of the trottle on rapid deceleration.

You can get a carb./vacuumhose-setup printout at Toyota dealers...;)
