What to Look for When Buying Used Truck Fuel Tanks

Buying used truck fuel tanks saves money when it's time to replace them. However, used fuel tanks demand more inspection than new ones to avoid risks. Thoroughly checking any second-hand tank before purchase is crucial to finding one that will provide years of reliable performance without problems down the road. 

Hundreds of used fuel tanks come through our shop, so we know a thing or two about buying and selling them – read on for expert advice. 

Check Exterior Condition

First, closely inspect the overall exterior condition of any used truck fuel tank you are considering for signs of corrosion, which can weaken a metal tank over time, and look for any dents, deformations, holes, or other exterior damage.

Minor dings from handling or surface rust may be acceptable but walk away from truck fuel tanks with extensive corrosion or defects.

Also, verify there have been no amateur repairs made, like welding to patch holes or cracks - while professional repairs are acceptable, amateur fixes won't hold up. Ask if any repairs have been made. Reputable sellers will disclose this.

Ensure Tank Integrity

Used fuel tanks should maintain complete integrity with intact original baffles and interior coatings. Fuel tanks contain slosh baffles, which prevent fluid movement and add structural stability. Make sure the tank you select retains both original baffle plates.

Tanks devoid of baffles risk collapsing from the fluid motion of diesel. Also, verify any protective interior coatings are still largely intact rather than scrubbed off by years of fuel and debris – this is common on fuel tanks over 15 years old. 

Complete Supporting Parts

When buying a used tank, make sure all supporting parts are included. These accessories play critical roles in preventing tank damage. Ensure the purchase includes a complete set of mounting brackets, cushioning rubber mounts, locking fuel caps, and keys.

You'll likely have to source and purchase replacements if accessories are missing or damaged. So be sure only to select fully intact, complete fuel tank systems.

Assess Fair Market Value

To determine whether any used fuel tank presents an intelligent purchase, assess its fair market price based on capacity, brand, condition, and included parts.

Depending on these variables, expect to pay £400-£1,500 or more. Larger capacity tanks fitting long-haul brands like Mercedes, Scania, or Volvo fetch higher prices, nearing £1,000 or more in good shape. More compact tanks for smaller rigs typically sell for £400-£800.

Like when buying a used truck engine, your goal is finding a fuel tank priced appropriately based on make, model, mileage, demand, and condition. Be wary of deals which seem too good to be true. Use fair market value ranges as a guide when negotiating prices.

By thoroughly inspecting any used fuel tank's exterior, interior, included parts, and price, you can zero in on one that meets your requirements at a fair cost.

Taking time to assess options carefully will pay off tremendously in the long run. Feel free to contact us if you have any questions.
