Attached is a DIY to replace the Brake Booster Vacuum Hose.

The brake booster vacuum hose is the line that connects the brake booster to the intake manifold on the engine. Due to the location of the connection on the intake manifold, the ridged piece of plastic inside the hose (connector) often gets broken due to pressure placed on the hose while working on other items in the area such as the MAF and Crank-case breather hoses.

Thank you to DIYGirl for the great explanation on replacing the brake booster hose. I broke it while replacing the valve cover gaskets.
However I am unable to extract the yellow tube. Inserting a screw continues to crack and remove a little of the yellow tube. I'm afraid if I keep going I will end up with bits of plastic in the intake manifold. My question is, can I pry out the Clamping ring with the yellow tube and O ring still in it. I don't want to dig this hole any deeper but I need to fix this. Thanks Larry

Sorry, Larry. @DIYGirl has not been here since 2014. That mention may work but I'll press the clever folk button too:
