where does this hose go on a 13B-T? (1 Viewer)

Hey muds,

I was tinkering on my veg system and found this loose hose on the intake side of my 13b-t. There is a small plastic connector on a nearby hose to hold this hose, but I don't know where it goes. It has #4 stamped on it and Y's into with a #5 hose that is tied into the top cross intake "Turbo" tube across the top of the engine. Both these #4 and #5 Y into somewhere that is unknown to me. Anyone know what this hose is? and where it goes?

This is 13b-t engine hose, not veg oil equipment hose, just for the record.

Really hard to see in that picture which hose that is, but that side of the engine doesn't have much. There is a solenoid that's located down below there that closes the vacuum shutter on the intake. There is also a hose that runs between the crossover, boost compensator, and bottom of the intake below the heater element. Are you saying yours is loose and doesn't connect, or you just can't see where it ends?

Thanks OilHammer, the hose is loose and I don't know where it should be connected to.

Okay, assuming you still get decent acceleration, and that your motor shuts off, It leaves the vent, or the a/c idle up solenoid. Can you tell where the other end is attached? Do you have a/c and does it idle up correctly?

As for acceleration, after 2300 RPM or so it just makes a whole lot of noise. I'm toying with the turbo right now, with a pyro and boost gauge on the way. The thing has been ugly slow to me since I bought it in December. I unplugged the wastegate hose last time for 30 seconds, and I finally heard the turbo spool when I was dirivng. I have never heard it spool before, but the green light comes on. I don't think the turbo is doing much as it is.

I do have AC, and it blows super cold. It idles up a little bit (you mean when I turn on the AC, right?) not a huge amount, but maybe 100 rpm, and it blows ice cold.

Keep it coming!

You should feel it when the turbo spools, not just hear it. There is a flying saucer looking thing on the back of the injection pump. there should be a vacuum hose, with little clamps, going from it to where the intake turns under. There is a nipple on the bottom of the intake just below the intake heater. Those two should be hooked together.

There is also a hard line vacuum pipe that runs around the back of the head, but I don't remember what it's stock use was for. If you look behind the injection pump, you should see it back there as it comes around just above the bellhousing. I have mine hooked into the intake cutoff solenoid directly, but I think there was an extra hose originally.
