65 FJ40 Heater Valve Under Dash (1 Viewer)

[toosdaejb]

Hi folks,
I have a 65 FJ 40 with the heater removed. I have this valve and attached hoses Under the center of the dash.
Can anyone identify and explain how this works?
I want to install a heater and assume this valve and hoses will be part of the project.
Grateful for any guidance here.
JB

That looks like a manual fuel line switching valve for dual fuel tanks.

I don't see any hose clamps. Could it be a rigged vacuum system?

Can you tell us ‘exactly’ where the one hose comes from, and where the other one goes to. Pictures if possible.

+1 for aux tank selector valve. Heater hose on mine is 1/2" and 5/8" inside diameter. The control valve is on the block.

As other have said, that's non-stock for some sort of cutoff. Do you have dual fuel tanks? Also that switch with the bezel that I think reads "pull for def" is non-stock. Where that manual valve is located is about where your heater on/off and vent pull cables mount to a little bracket thing. I can send you a pic if needed.

Here's where I started my heater journey: PNW 67 Patina Blue - https://forum.ih8mud.com/threads/pnw-67-patina-blue.1289865/page-4#post-14699350. I hope that helps you track down what you need.

Thanks for the help here. The two hoses have “fuel injection” printed on them and both attach to lines Are shown in the pix taken under the FJ

Very grateful for the insights. Definitely non-stock. I don’t have dual tanks. I’m wondering if it’s some type of older fuel injection valve.

That looks like the Transfercase . looks like someone rigged up the vacuum

Not sure on the the 65 but i know on the 69 there is a lever under the dash . I just took it out of mine

If the hoses were for coolant or fuel they would have clamps on them.

The valve and hoses are too small for effective heater operations controlling hot water. Might be some sort of Gerry rigged vacuum controller for the 4 WD using a fuel valve selector.

Exactly right Firemedic831! I found the diagram. Many thanks

Fascinating! Redneck for sure. But I have to admit, it’s also a bit intriguing. All four of my current LCs have the vacuum shift, and I’ve broken my share of cables, and rebuilt my share of control boxes.
