'94 F150 XLT, 4.9L - Vacuum Lines
I'm trying to get this truck to pass emissions. Started with tune up - plugs, wires, cap & rotor. Now seeing that the vacuum lines are pretty bad. Lots of issues so I'll tackle one at a time. First, the stock lines that are a rubber elbow fitting and a hard plastic tube. The hard plastic tubes are brittle and snap if you move them. Are these replacement parts, like with a part number, or is this a replacement item that you fabricate yourself? Maybe there's a kit? Can I replace them with soft silicone lines? How have you guys handled this?

Hello. I came across this thread when looking for a vacuum line diagram for my '93 4.9L. I've highlighted the line that's broken on my truck on seagiant's image. I'm not familiar with this component, but the line is brittle. I'll have to remove some tape and peel back the flexible conduit to add new line. Can anyone tell me what it is?

Hi,
I bought this, it will slip right on the fittings!
Here's a pic, not my truck but what I did!
