Ford F-100 Fuel Tank Straps
Ford F-100 Fuel tank straps
Starting at $16.95, AutoBuffy stocks 5 fuel tank straps from SKP and Dorman for the Ford F-100. A fuel tank strap is a metal band that bolts to the vehicle's frame and cradles the fuel tank in place underneath the vehicle. When a strap rusts through, loosens, or breaks, the tank can shift, stress the fuel lines, or drop entirely — a serious safety hazard.
Signs your Ford F-100 needs new fuel tank straps
- Visible rust, cracks, or holes along the length of the metal strap when inspected from underneath
- Fuel tank visibly sagging, tilting, or sitting unevenly beneath the vehicle
- Clunking or banging noise from under the rear of the vehicle when driving over bumps or rough roads
- Fuel filler neck or fuel lines showing signs of stress, kinking, or pulling at their connection points
- Strap mounting bolts are seized, stripped, or missing entirely during a routine undercarriage inspection
- Strong fuel smell while driving, caused by stressed or kinked fuel lines from a shifting tank
Which fuel tank strap should you buy for your Ford F-100?
The most important factors are material quality and OE fitment. Fuel tank straps mount in a precise position and must match your exact Ford F-100 tank configuration — the wrong strap can leave the tank under- or over-secured. Straps are typically sold individually or as a set, and most Ford F-100 applications use two straps, so confirm whether you need one or both before ordering.

Replacing fuel tank straps on a Ford F-100
Moderate⏱ 1–3 hoursFloor jack and jack stands or a vehicle liftRatchet and socket setBreaker bar (for seized strap bolts)Penetrating oil (for rusted hardware)Transmission jack or wooden support board (to support the tank while working)
Support the fuel tank with a jack or board before loosening the strap bolts so the tank doesn't drop unexpectedly. Disconnect the filler neck and fuel lines only if necessary to lower the tank enough to swap the straps — on some Ford F-100 applications you can slide new straps into place without a full tank removal. Once new straps are positioned, snug the mounting bolts evenly and check that the tank sits level with no stress on the fuel lines before lowering the vehicle.
Frequently asked questions
How much does it cost to replace fuel tank straps on a Ford F-100?
Parts start at $16.95 for a single strap at AutoBuffy. A full DIY job — buying both straps — typically stays well under $100 in parts. Shop labor adds roughly one to two hours of labor time depending on rust and access. Replacing both straps at once saves you from doing the job twice.
Can I drive my Ford F-100 with a broken or rusted fuel tank strap?
No — a failed fuel tank strap is a safety issue, not a deferred maintenance item. A loose or broken strap allows the tank to shift under load, which can stress fuel lines, damage the filler neck, or cause the tank to drop from the vehicle. Stop driving and replace the strap before returning to the road.
Do I need to drop the fuel tank to replace the straps on my Ford F-100?
Yes, in most cases. The tank typically needs to be lowered enough to unhook the old straps and thread new ones into position around the tank. You do not always need to remove the tank completely, but you must disconnect fuel lines and the filler neck if dropping it fully for easier access.
How many fuel tank straps does my Ford F-100 use?
Most vehicles use two straps — one near the front of the tank and one near the rear — working together to cradle the tank. Some larger trucks or vehicles with auxiliary tanks may use a different configuration. Check your specific Ford F-100 listing on AutoBuffy to confirm how many straps your application requires.
Should I replace both fuel tank straps at the same time on my Ford F-100?
Yes. Fuel tank straps on the same Ford F-100 are exposed to identical conditions — road salt, moisture, and age — so if one has failed or shows heavy corrosion, the other is typically close behind. Replacing both at the same time costs little extra in parts and avoids repeating the labor of dropping the tank a second time.
What causes fuel tank straps to fail on a Ford F-100?
Corrosion is the primary cause. Steel straps are constantly exposed to road moisture, salt, and debris from underneath the vehicle. Over time, rust eats through the metal, weakening the strap until it cracks or snaps. Straps on older vehicles or those driven in northern climates with road salt are especially prone to early failure.
