Hey i have a 84 K20 that i am working on. And i am putting in new gauges. For the fuel gauge what wire do i hook to the sender plug on the gauge. This junk asx book i have says its a tan/white wire. But the only tan/white wire i can find goes to the proportioning valve. Thanks in advance

Yep, that's correct - for the auxiliary (RH) tank .

And, there should be a pink/white lead that goes from the Pollak valve to production (LH) tank.

The lead that runs from the instrument panel (goes through the firewall) and connects to the Pollak valve is just plain pink.

It is in the same harness loom as the rear lighting group.

First of all;

Do you have dual tanks?

Is the tank select valve in place and operational?

Is there a tank select switch mounted and wired - on the dash board?

Did you see this:

I did there is a pink/black.wire that comes out of the top.of the tank and goes to the tank selector valve

Yep, that's correct - for the auxiliary (RH) tank .

And, there should be a pink/white lead that goes from the Pollak valve to production (LH) tank.

The lead that runs from the instrument panel (goes through the firewall) and connects to the Pollak valve is just plain pink.


That explains where each of the leads involved in level sensing runs (in a dual tank system) - and also what each end is connected to.

To recap:

The pink goes from the dash to the tank select valve (Pollak is just the name of the manufacturer).

Two wires come out of the Pollak valve (a pink/black & a pink/white).

The pink/black goes to the tab on the sender head of the auxiliary (RH/passenger side) tank.

The pink/white goes to the tab on the sender head of the production (LH/driver side) tank.

If you don't have (or are not using) a dual tank set-up, then the solid pink wire needs to go directly to the production tank (LH side).

These images show how the pink wire is connected to the stud on the sender head. The blue (sometimes black) wire connects to the spade type tab to a nearby grounding point and is connected by a bolt to the frame:

Chengny said it above, twice!

Pink/white to left hand tank
Pink/black to right hand tank

which both go to the selector valve on the frame and then turns into a solid pink wire which goes to the gauge, so find the solid pink wire.

Whoa Nelly !!! Don't make me pull this bitch over !!! Just an FYI, This isn't Pirate 4x4 where such comments and name calling are tolerated when you disagree with someone. We have many many disagreements here, even the long time seasoned veterans, but we still disagree like adults. We'll have our immature fun, but there's not an ounce of toleration for this type of comments. Soooo, I"ll clean up the thread a bit and we'll carry on.
