TRQ Gas Fuel Tank 42 gal Compatible with 1998-99 Chevrolet Suburban

In this review of the TRQ Gas Fuel Tank 42 gal for 1998-99 Chevrolet and GMC Suburban models, the bottom line is practical: this is a direct replacement for owners who need a like-for-like fuel tank without fabrication. The reviewer found value in the tank's precise fit with factory GM gas caps and a quality liquid-painted finish that resists corrosion. Installation can be straightforward for hands-on DIYers who follow the vehicle fitment guidance and watch the TRQ DIY video resources, though some users reported tighter clearances during fitment.

Key Features

• Direct fit compatibility: Designed for 1998-99 Chevrolet and GMC Suburban K1500/C1500/K2500/C2500 models so it matches original mounting points for a clean replacement.
• 42 gal capacity: Provides equivalent fuel capacity to the original tank for preserved driving range and fuel system performance.
• Zinc coated steel construction: Offers improved corrosion resistance over plain steel, helping the tank last longer under road conditions.
• Liquid painting finish: The painted coating improves surface durability and customers report a neat paint quality out of the box.
• Pre-assembled O-ring included: Comes with the O-ring to help seal components and speed reinstallation compared with sourcing small parts separately.
• DIY video support: TRQ provides online how-to videos to help confirm procedures and reduce guesswork during installation.

Who It's For

This tank is aimed at owners of late 1990s Chevrolet and GMC Suburban trucks who need a full replacement fuel tank that fits factory connections and uses the original filler and cap. It suits DIY mechanics comfortable with underbody work and removing and reattaching straps and fuel lines, especially when they use the available TRQ installation videos.

Those who should look elsewhere include buyers who require sending units, straps, lock rings, or mounting hardware included with the part, since this tank does not come with those items. Also, if exact original dimensions are critical for modified or heavily altered frames, verify fitment carefully before purchase.
