So I've been wrapping up my motor build and I believe ive just about figured out my EGR delete so I'm putting the rest of my EFI back together. I need some help on what a few of these hoses/tubes may be to. Here are a few pictures of what I'm talking about, one hose almost looks like a type of fuel line however I cant seem to find where it goes.... mabe a EGR tube that can be done away with, same for the one under the EFI?

 

Pretty sure the first one is the return line to the fuel tank off the pressure regulator

 

Take a broader picture so we can see where you are on the engine, can't seem to focus on the pics you have.

 

Alright thanks guys, I'll take some more pics tomorrow when it gets light

 

Gates 18222, Gates 18223, and Gates 18400.

The 18400 or equivalent can be purchased at any of the auto parts stores because it is a stocking item. It's an U-shaped coolant bypass hose. It's hooks to the new coolant bypass fitting you have under the intake.

All the above coolant hoses fit a 1992 22RE 2wd with the coolant fed idle air valve, and up under the intake manifold just fine. Have had all three installed since August 2017...still look new.

Last time I checked, Toyota wanted more than $40 plus shipping for the Gates 18222 equivalent. No way I am going to pay that much for a little dinky hose.

 

Alright guys here's a pic i found on Google, the two blue circles i have found the answer to (as shown in the picture) still looking for where the tube in the red circle goes. As you can see they come off of the passenger side timing cover under the EFI system

 

Red circled tube goes to IAC valve. What year is your truck?

 

I dont believe I have a IAC valve.... my truck is an 86, is it possible I over looked it?

 

1st gen ran a coolant hose to Aux Air Valve. Here is a thread about it: https://www.yotatech.com/forums/f116...k-like-143319/

 

very much appreciated! I think you answered my question

 

It's the hose 22230S all the way to the left in this diagram:
