Fuel level float arm

[CaptFrank2001]

I saw a video (don't remember which one) that shows bending the arm to the fuel level float. I did a test fit & it doesn't look like it needs to be bent. What's the reason for bending it? TIA

The DF gas tank has internal baffles and outer walls that the arm could bump into.
Basically the original arm is made for the bigger Cobalt tank.

It's unfortunate that the baffling is where it is. In order to correct the fuel gauge to this tank, it could be done by straightening the arm out some (in just the right manner) but the it will contact the baffle.

Kaleb and I did a lot of measuring and calculating and determined it really can't be corrected with the baffling in the way.

The original tanks (first ten I think) had a wall that completely sectioned off the pump side of the tank from top to bottom with a one-way trap door to hold the fuel near the pump.
The tall wall made it necessary to bend the float wire.

The current tanks have a short wall top keep fuel near the pump during long left-hand turns.

Looking in the tank at the baffle it seems like I can put the fuel pump in with NO modifications. The short baffle (maybe 1-1/2' high) does not appear to interfere with the float arm on the fuel sender.

Installation of the pump doesn’t seem require bending of the arm but if you wanted to correct the detection of the fuel level, you would have to straighten out the arm to shorten the full arc movement of the arm and if I remember correctly, even the short baffle is in the way if the arm was bent more straight.

When the tank is physically full of fuel, it causes the float and arm to move above the or beyond its normal limit when full. So the level in the tank has to drop a couple of inches before it starts to read anything less than full.

Hard to explain. I may have to draw it out.
