I have a 1995 4Runner 3.0 and have searched everywhere I can online for a definition of this pipe/tube and cannot find the right info except this photo that I borrowed from someone here and with the RED arrow. It's a U shaped pipe with a smaller pipe connecting to a small hose going to the top of the intake manifold. The larger hose connects to the heater valve assembly.

Hopefully someone knows the answer ��? TIA

Aloha ��

 

You have checked Toyota Parts dealers online ??

Every 4 runner of that age I see the rear heater is long gone .

It seems once the heads come off it is never reconnected

 

 

I'm seeing that pipe as 87265-89108 or 89109. I usually use the parts diagrams here https://parts.lakelandtoyota.com/pro...erm=8726589109

If I've got the parts right, it looks like they are discontinued and you'll be surfing ebay.

 

Similarly, look for a "reducing tee" fitting. These typically have 2 measurements: the size of the 2 larger connections, and the size of the single smaller connection. I'm not 100% sure of Toyota's measurements, but you should be able to find some standard sizes that are close enough.



Also, they're dirt-cheap.

 

You could make one out of copper and solder a nipple on
