Frequently Asked Questions About Peterbilt 330/335/337 Fuel Tanks

What size fuel tanks are available for my Peterbilt 330, 335, or 337, and how do I determine which fits my truck?

Fuel tanks for these models typically range from 25 to 100 gallons, with 50 and 75-gallon options being most common. To determine the correct size, check your door jamb sticker for the original tank capacity or measure your existing tank's dimensions (length x height x width). Most 330/335/337 models from 2005-2015 use either a 26-inch or 23-inch diameter tank. The mounting strap spacing is crucial - measure center-to-center between your existing straps to ensure compatibility.

Are these fuel tanks made of aluminum or steel, and which material is better for my application?

Both aluminum and steel tanks are available. Aluminum tanks are lighter (reducing overall vehicle weight by 40-60 pounds), resist corrosion better, and are ideal for trucks operating in northern climates with road salt exposure. Steel tanks cost approximately 30% less, are more impact-resistant, and work well for heavy-duty applications. Most owner-operators prefer aluminum for the weight savings and longevity, while fleet operators often choose steel for the lower initial cost.

Will I need to modify my truck or buy additional parts to install a replacement fuel tank?

In most cases, direct replacement tanks require no modifications if you match your original specifications. However, you will need new tank straps (usually sold separately) as reusing old straps is not recommended for safety reasons. Additionally, you'll need a sending unit if your tank doesn't include one, fuel line fittings that match your truck's year (some 2008+ models use different connections), and new rubber isolators between the tank and frame. Budget an extra $150-250 for these installation components.

What's the difference between round and D-shaped fuel tanks, and which style fits my Peterbilt?

Round tanks are the standard configuration for most Peterbilt 330/335/337 models and mount with traditional strap systems. D-shaped (or rectangular) tanks are typically found on trucks with limited frame space or custom body applications, sitting flush against the frame rail. Check your current tank configuration - if you have frame-mounted equipment like toolboxes or hydraulic reservoirs, you likely have a D-shaped tank. Round tanks offer easier installation and more universal strap options, while D-shaped tanks maximize fuel capacity in tight spaces.

How long do these replacement fuel tanks typically last, and what warranty coverage is standard?

Quality aluminum fuel tanks typically last 15-20 years with proper maintenance, while steel tanks average 10-15 years depending on climate conditions. Most reputable manufacturers offer a 1-2 year warranty against defects, with some premium brands extending to 3 years. The warranty usually covers manufacturing defects and leaks but excludes damage from improper installation, accidents, or corrosion from external factors. Regular inspection of tank straps and cleaning of the tank bottom where debris accumulates will maximize lifespan regardless of material.
