Frequently Asked Questions About Kenworth T700 Fuel Tank Accessories

What size fuel tank straps do I need for my Kenworth T700, and are they universal?

Fuel tank straps for the Kenworth T700 are not universal and depend on your specific tank size and configuration. Most T700 models use either 26-inch or 31-inch straps, but the exact size depends on whether you have a 100, 120, or 150-gallon tank. Measure from the bottom of your tank to the mounting bracket, or check your VIN-specific build sheet to ensure proper fitment. Using incorrect strap lengths can cause tank movement and potential damage.

Will aftermarket fuel tank steps and brackets fit my 2008-2019 T700 without modifications?

Most quality aftermarket fuel tank steps and brackets designed for the T700 will fit 2008-2019 models without drilling or cutting. However, there are slight variations between model years, particularly in the 2013+ models which have different mounting hole patterns. Always verify the product specifies your exact year range. Pre-2013 models typically use a 3-bolt pattern, while 2013+ use a 4-bolt configuration for tank-mounted accessories.

What gauge aluminum or steel is recommended for T700 fuel tank covers and guards?

For optimal durability, fuel tank covers should be at least 16-gauge steel or 0.080-inch (approximately 14-gauge) aluminum. Thinner materials tend to vibrate excessively and can crack at mounting points within 12-18 months. Stainless steel options in 18-gauge also work well but require proper mounting hardware to prevent galvanic corrosion when attached to aluminum tanks.

Do I need special tools or professional installation for T700 fuel tank accessories?

Most fuel tank accessories like straps, steps, and covers can be installed with basic hand tools including socket sets, wrenches, and a torque wrench. However, fuel tank removal or major bracket installations may require a transmission jack or helper due to weight. Always disconnect batteries and ensure tanks are less than 1/4 full before beginning work. Professional installation is recommended for anti-siphon devices or any modifications requiring fuel system disconnection.

How do I match chrome, polished, or painted finishes with my existing T700 accessories?

Kenworth T700s came with three primary finish options: mirror-polished stainless, chrome-plated steel, and painted aluminum. To match existing accessories, note that factory chrome has a slightly warmer tone than most aftermarket options. Polished aluminum accessories will not match chrome exactly but blend well with brushed or satin finishes. For painted items, use Kenworth paint codes (found on your door jamb sticker) to ensure exact color matching, especially for metallic finishes.
