SOURCE: carburetor fuel flow

Hi and welcome to FixYa,

Initially, to your queries:

  • hook up all the vacuum lines - yes or cover/plug all
  • to stop fuel flow - hooking up all the vacuum lines or covering/plugging them would be technically correct but will not stop the flooding/fuel overflow;
  • run correctly - with constant overflow/flooding, it will not run correctly.
To my knowledge, overflow could only be caused by:
  • faulty valve pins, worn out rounded pyramids, necked/indentations on the surface of the rounded pyramid, cracks (rubber type);
  • worn out inlet port;
  • dirt, sand, foreign object lodged against inlet port hole;
  • mis-adjusted floats;
Which would mean, go to do it all over again.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

SOURCE: how do i hook up the fuel line and vacuum line on

the fuel line(the bigger of the two)which will come from either between the carbs or offthe left hand carb,is connected to the main fuel tap(larger outlet) and the vacuum line will come from the front of one of the carbs(on the engine side)and should be tapped into the inlet manifold,this pipe (smaller dia)goes to the other outlet on the fuel tap,these are a vacuum pump inside the fuel tap assembly

Vacuum line issue

In most GM vehicles only two vacuum lines pass through the firewall. One as you mentioned is the vacuum source (your black line) the other usually controls a valve that turns off coolant flow through the heater core while the A/C mode is turned on.

I have a 1981 Suzuki GS750L. Not sure where the vacuum line from the carb hooks up to. Bike has not run in 20 years. It was a basket case. I am putting it back on the road. I see there is a vacuum...

The petcock has a diaphragm and needs a vacuum to allow fuel to flow, It is a safety fuel shut off, if the engine stops NO VACUUM, NO FUEL to carbs, there is usually a vacuum take off on the inlet manifold pipe between the carb and the engine. Hope that helps

I replaced the ac compressor a 97 Chevy Lumina 3.1 and everything is working right. The air is blowing through defrost vents but it is not blowing through front vents. Its a vacuum line loose that is...

The ball is a vacuum tank. It would take the active vacuum line on one side and the other would go to the vacuum line that leads to your ventilation controls. Connect a length of vacuum hose to either side and BLOW through it. If you can't blow through it, that's the side that goes to the engine since it would have a check valve to prevent the vacuum from escaping when the engine is off. If you can blow through both sides, then it doesn't matter which hose goes to which side.

When i switch my heat or air from defrost to aut or vis versa the air only comes out defrost vents what wrong?

The vent doors in and under the dash are conrolled by vacuum lines. Checkthese plastic doors to see if they opperate smoothly and the vacuum hoses are hooked up right. See where the vac lines come from and make sure they r hooked up. Also make sure the vent direction switch is hooked up to the vac lines. Good luck

What would be casing a 1994 diesel to loose brake petal while the vacuum pump is hooked up i have replaced all of the brake a ponets such as master cylinder and brake buster brakes rooters

If your model has a Vacuum Reserve cannister, its probably rusted out on the bottom. This part use to look like a Coffee can and has a Vacuum line to it. (Plastic would have been a better material.)

If that is not the problem, you can hook up a manual Vacuum Gauge tester to the line that hooks up to the pump on the engine. The line should hold Vacuum. If it does not, start backtracking all of the hose connections. Eventually you will find a line that does not hold Vacuum. It could even go to a Power brake booster.

I had bought a used Diesel truck and the guy paid big money for a new engine-driven Vacuum pump. I kept dropping my Cruise Control up hills. I used a Vacuum tester and found my Vacuum Reserve cannister was rusted. The seller paid $300+ for a part not needed.

I have A 1985 Pontiac Trans Am with A 5.0L E4ME carbonated engine and I had to remove all the vacuum line's and I need to get A diagram to hook it all up again. Or since I don't need to pass any emission...

You need to hook the vacuum advance for the distributor to the front lower left on the carb. The PCV valve goes in the center bottom front. The dashpot for the choke goes upper left front. The vacuum to the brake booster goes in the lower middle at the rear. If you have a second vacuum pot on the rear on the choke side it needs vacuum from the front. The transmission vacuum usually hooks to the rear on the intake. This is all you need. The rest of the ports on the carb and intake can be plugged. Hope this helps.

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.
