Just bought me a new 6.0 and have a few problems

[06pwrstrokerbullitt]

So I have a few problems, they aren't to bad but I would like to fix them.

1. Fuel gauge does not work. I bought a new sending unit to put in it and I plugged it in without installing it and I moved the floater around and it didn't change the gauge at all. The gauge will come from the very bottom to E when you first turn the key then it falls back to the bottom again. I was wonering if it is the gauge that is broke but the low fuel light on the display pops up also. Would it read off the gauge?

2. The auto locking hubs don't work. I turn the 4wd switch inside and it don't lock 4wd in. I can manually turn the hubs from auto to lock and 4wd works fine. I checked all vacuum lines all the way up to the vacuum pump I guess and they all seem fine and intact.

3. Last problem is there are a few burnt bulbs behind my gauge cluster. I am about to go attempt to pull the gauge cluster now. Is this a hard task? A couple bulbs look burnt out and one flickers on and off when you first turn the lights on then it will stay on.

what year is this truck?

the problem with gauge could be in the dash itself, i mean if you are having problems with the lights and whatnot then maybe that cluster is junk.

the 4x4 is most like a vacuum leak, but you say you checked. I know my doesnt work unless i switch the hubs.

how many miles on this truck and what kind of condition is it in?

For the hubs, if you have already checked the lines, check the vacuum pump. The ford fuel guage is slow to recover and show the level, if you reconnect the new float and let it sit stationary at a mid way point, give it a minute and see if the gauge is moving.

I wonder if these problems are related? Have you checked your fuses?

It's the truck in my signature and it has 80k miles on it.

After I connected the new sending unit I did give it a few minutes with the key on and it never did anything. With the hubs the vacuum pump is pumping but when I pull a line off from it, it doesn't have much vacuum at all? I have checked all fuses that I can see and I thought might be related.

The DISENGAGE vacuum specs are 5.7 to 7.25 in-Hg. The ENGAGE specs are greater than 9 in-Hg. Check your vacuum readings at the supply hose to the hubs as you engage, and disengage 4WD using the selector switch. If your vacuum readings are within the specs I've listed above, your problem is in the hubs themselves.

Well I fixed all the lights on the gauge cluster. I put new bulbs in it but one still flickers till it warms up.

Oh yea I don't know if this would make a difference with the fuel gauge but the previous owner had an auxillary fuel tank in the bed of the truck. Would that mess with the gauge at all? Would they unhook something to tie it in with the gauge?

BUMP BUMP, I still gotta try to fix this dead fuel gauge.
