What F01024 Actually Is
F01024 identifies a 3.25-inch fuel tank cap with a quarter-turn locking action. Aluminum body, designed to drop onto the fill neck, twist a quarter turn, and lock. No threading, no fighting a coarse thread with cold hands at a fuel island. It seals the tank against fuel slosh, dirt, and water intrusion.
The cap listed here is a premium quality aftermarket direct replacement built by World Truck Parts. It is not sourced from or authorized by the truck manufacturer. The F01024 number is shown so you can identify the part you already have and match the size and locking style before you order.
Application per the supplier data is Freightliner, model years 2014 through 2024. That range is a guide only. Fill neck diameters and cap styles changed across tank suppliers, so confirm your truck by VIN or by reading the number off the old cap before you commit.
Why These Numbers Cross
The Automann number 572.1018 crosses to F01024 because both describe the same physical cap: 3.25-inch nominal fill neck size, quarter-turn cam lock, aluminum construction. Aftermarket suppliers assign their own catalog numbers to a part they build to the same dimensional envelope, then publish the truck manufacturer number so buyers can find it. That is all a cross-reference is.
What makes a fuel cap interchange is short list: neck diameter, the locking mechanism and the number of lugs, the gasket seat, and whether the cap is vented or sealed. Get those four right and the cap works. Get the diameter wrong by even a quarter inch and it either falls off or will not seat.
These numbers are listed for identification only. We are not affiliated with, endorsed by, or authorized by Freightliner or Automann. Use the cross-reference as a starting point, then verify against the part in your hand or against your VIN. A cross-reference is not a fitment guarantee.
How Fuel Caps Fail
The gasket is usually first to go. Diesel, UV, road salt, and steam cleaning harden it until it takes a set and stops sealing. You'll see fuel weeping down the tank side after a hard corner, or a fuel smell in the cab. Pull the cap and flex the gasket. If it's stiff or cracked, it's done.
The other common failure is the quarter-turn cam itself. Lugs wear, the cap goes loose in the neck, and vibration walks it open. Some caps just get knocked off the neck at a fuel island and never come back. If the cap spins freely without locking, replace it rather than trying to shim it.
F01024 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to F01024. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
How do I confirm my truck takes a 3.25-inch cap?
Pull the old cap and measure the fill neck opening across the inside diameter, or read the number stamped on the cap face. Do not measure the tank hole with the cap installed. If the old cap is gone, verify by VIN through your dealer before ordering.
Is 572.1018 the same part as F01024?
They cross to the same cap style: 3.25-inch, quarter turn, aluminum. Both numbers are listed for identification only and neither implies any affiliation with the companies that issued them. Confirm the size and lug pattern against your old cap before ordering.
Can a bad fuel cap cause a check engine light?
A cap that will not seal lets air and moisture into the tank and can trigger fuel system and emissions faults on newer trucks. It also lets water in, which ends up in the separator or worse, at the injectors. Replace a leaking or loose cap instead of running it.
