Default IAC vacuum lines

Has anyone used different lines than the OEM?

I know they currently available for $40-50. Seems a lot for some hose.

I can see some fine cracks forming on mine so I'll need to replace when it starts leaking. Isn't anything close to what is shown in pic on there but I'm looking at replacement before year end to stay ahead of it.

I replaced mine with fuel line, works fine. The smaller one was 1/4" I.D. larger one might have been 1/2" I.D. but cannot remember.

That helps. I'm going on a multi state trip this weekend so I don't want to mess with pulling off yet I'll probably destroy them.

I am assuming you are referring to the rubber connector piece on the end where it attaches to the iac as the lines themselves are a hard plastic formed to make the turns. (hence the cost) You would think they would sell that connector piece separately. You should be able to find rubber hose to fit. Yea that center one is larger id than the other 2. While your at it you may want to replace the 2 rubber connectors on the lines at throttle bodies.

I thought that looked like plastic. Rubber on ends has no hope to last attached to two rigid points. I was thinking to replace the entire line but I suppose only the ends might be replaceable.

The difficulty is in reaching the lines. They sure didn't leave room to work.

I'm not sure where those other two rubbers you refer to are located. Have to do some more looking.

And just to be clear, I completely replaced the hard lines.

That's what I thought you meant. Fuel line as you said or I can order silicone lines both will last longer than cheap rubber.

The lines wrap around the jugs and up to the front and other to backside of the throttle body just above the fuel injectors. The middle one goes to the bottom of the air intake And yes they are a pita to work with. You got to remove the coil pack and work from the left side, and hang over the tank toward the right side to see what your doing. Hope you got small hands. Hang on to that connector so you can cut the 3 hoses to the proper length as the middle one is a different length.
I found that a little silicone grease helped a lot to slip the lines on.
