The Toyota 4Runner is a midsize SUV produced from 1984 to current across 6 generations, with the modern 4Runner being one of the longest-running body-on-frame SUVs still in production. Our gas tank coverage focuses on the 4th generation (2003 to 2009), the 5th generation (2010 to 2024, the longest single 4Runner generation), and the new 6th generation (2025 to current). The 5th generation 4Runner became iconic in the off-road and SUV communities for its rugged body-on-frame construction, locked rear differential availability on TRD Off-Road and TRD Pro trims, and the proven 4.0L 1GR-FE V6 engine (270 hp). The 6th generation (2025+) introduced a new 2.4L turbo hybrid powertrain (i-FORCE MAX) replacing the V6.
The gas tank on the 4Runner is a stamped steel construction designed for the rugged SUV application. Tank capacity is approximately 23 gallons on most variants, providing the long-range capability owners expect from a body-on-frame SUV. The tank is strap-mounted to the chassis frame rails with two heavy-duty steel straps, positioned between the rear axle and the rear cargo area floor. Internal baffles control fuel slosh during off-road maneuvering. A top-of-tank service plate provides access to the integrated fuel pump assembly. Multiple ports accommodate the low-pressure fuel feed, fuel return (early models), vapor canister vent, and fuel level sender wiring.
The most common reasons Toyota 4Runner owners replace the gas tank are: rust corrosion progressing to pinhole leaks (very common on 4Runners driven in salt-belt states, typically appearing at 10 to 20 years of age), pinhole damage from off-road impact (TRD Off-Road and TRD Pro variants used aggressively off-road can suffer rock damage), strap mounting point deterioration (rust at the strap contact areas weakens the structural connection), separated tank seam from impact or corrosion, deteriorated rubber inlet hose causing fuel leaks at the filler neck, leaking fuel pump access plate gasket allowing vapor escape, or impact damage from accidents.
4Runner owners typically replace the gas tank during major fuel system service when corrosion or impact damage compromises safety. Driving with a leaking fuel tank is a serious fire hazard and emissions violation. Our new OEM-specification 4Runner gas tanks at $329 save significant money over $700 to $1,100 dealer pricing. Plan to replace mounting straps (typically $40 to $80 separately), inlet hose, fuel pump assembly (often a good idea during tank service to avoid future labor), and gaskets during the tank replacement. The complete tank service is a full Saturday DIY project or a half-day at a professional shop.

Not directly compatible with earlier 4Runner generations (1st gen 1984 to 1989, 2nd gen 1990 to 1995, 3rd gen 1996 to 2002) which use different tank designs. The 6th gen 4Runner (2025+) uses a different tank for the hybrid system, NOT interchangeable with 5th gen V6 tanks. Within the 5th generation (2010 to 2024), the tank design is consistent with minor year-to-year revisions. The 4Runner is closely related to the Lexus GX (different vehicle but similar Toyota body-on-frame platform), but tanks are NOT directly interchangeable. Always confirm year and trim.
Not sure if this Toyota 4Runner gas tank fits your car? Call (240) 301-0095 with your year (2003 to current), trim (SR5, TRD Off-Road, TRD Pro, Limited, etc.), drivetrain (4WD or 2WD), and engine code if known. Our team confirms the right gas tank for your specific 4Runner application before we ship. The 5th generation (2010 to 2024) accounts for the majority of 4Runner gas tank sales due to that generation's 15-year production run.
These new OEM-specification Toyota 4Runner gas tanks are inspected before shipping. Quality control includes:
Each tank ships in a heavy-duty protective box with corner protection to prevent shipping damage. Apply care during installation to avoid scratching the anti-corrosion coating. Always replace the fuel pump gasket and inlet hose during tank installation since these are sealing-critical and often deteriorated on the old vehicle. After installation, prime the fuel system by cycling the key several times before starting, then verify fuel pressure for proper operation.
