Where to buy PVC hose and EGR vacuum hose?

These cracked on my car and I have them taped up. I want to replace them. But the dealer doesn't have them. Anyone know if any good aftermarket places that have these 3rd gen parts?

EGR uses regular vacuum hose and the PCV can be had from Bumber to Bumper or some parts store. DO NOT LET THEM TELL YOU TO USE REGULAR HOSE.

PCV has to be an oil-resistant hose like oil cooler or tranny cooler hose. You can get it from most parts stores if you ask for 3/8" tranny cooler hose.

But the problem is the vacuum lines from the EGR are hard formed plastic. I can't use hose because the way that they attach to the EGR solenoid is that they go inside, rather than on the outside like hose would. In other words, they are male, not female like a hose would be.

The rubber piece that they go into should pull off to expose male nipples for the hose to go onto.

Only on one side. There are 2 EGR related hoses. One hose connects between the EGR solenoid and the EGR valve. Yes, the connection at the EGR valve has a nipple on it. However, the EGR solenoid has no nipples on it. The hoses fit inside. Then, there is another hose that connects from the EGR solenoid to under the throttle body. Yes, there is a nipple at the throttle body, however, again, the EGR solenoid has no nipples. The hose goes inside of it.

The plastic lines that go to the solenoid plug into a rubber boot which makes a 90* bend into the solenoid. The boot can be removed from the solenoid. It's probably stuck on pretty good due to age, but it will come off. In fact, that's SUPPOSED to be how you unhook the solenoid. The lines aren't even supposed to pull out of the boot.

Be careful taking the boot off, the nipples that it goes onto like to break. You're probably better off cutting the boot off with a razor blade and replacing the lines with hoses.

Oh, I just seems that that rubber boot that the 2 hose go into were pretty integral to the solenoid, but maybe you're right. But I wonder if I remove the rubber boot how the solenoid will stay mounted to the bracket. I'll have to examine it a little closer next time.
