JJing 7-Gallon Universal Generator Fuel Tank — Direct-Replacement for 5000–10000W Units, Preinstalled Gauge & Installation Kit

This aftermarket gas tank is built to replace common OEM tanks used on Honda EC/EM/EB series models and a wide range of generators from Predator, Champion, Wen, Powerhorse, Powerland, Onan and other brands. The tank is sized to match popular hole-to-hole mounting patterns and comes with practical accessories—fuel petcock, fuel line, spark plug, air filter, gasket set and muffler pieces—to help you get a generator back into service quickly. Note that this model is unvented and its true usable capacity is slightly under 7 gallons, which mirrors many similar replacement tanks on the market.

Will this tank fit my generator model?

Compatibility depends on the tank footprint and mounting hole spacing rather than brand names alone. Measure your existing tank and compare dimensions before ordering to avoid returns.

• Mounting hole spacing: length 23.25" (hole-to-hole)
• Overall width: 16.1" and height: 6.1"
• Common fits: Honda EC6500/EM6500/EM5000S/EB6500 series and many Predator, Champion, Wen, Powerhorse, Powerland models
• Check the second product image for a size diagram before purchase

What accessories and parts are included with the replacement tank?

The JJing kit arrives with the small parts you need for installation and basic maintenance, saving you an extra parts hunt. These components are intended to replace worn rubber and fittings typically disturbed during tank removal.

• Pre-installed fuel gauge and rubber grommets for mounting
• Fuel petcock and fuel line for connection to the carburetor
• Spark plug, air filter and carburetor/muffler gasket set included
• Packaged to reduce risk of missing small parts during installation

Does this tank vent and is the capacity exactly 7 gallons?

This specific model is produced without a vent valve; that design choice affects how the tank breathes and how it must be installed. Also, like many aftermarket replacement tanks, the stated capacity rounds to 7 gallons but usable volume is a touch lower.

• No built-in vent valve — choose a vented model if your setup requires it
• Marked capacity: 7 gallons (26.5 L) but true usable volume slightly less
• If an exact 7.0 gallon vented tank is required, this is not the correct part
• Follow local fuel safety and storage rules when installing and using

How do I ensure proper installation and avoid returns?

Measure the hole-to-hole distance and the tank envelope against your generator before ordering. Many returns are due to size mismatches, not product flaws, so a quick measurement prevents wasted time and shipping.

• Compare your current tank measurements to 23.25" x 16.1" x 6.1" (L x W x H)
• Inspect mounting grommets and match hole diameters on the generator frame
• Confirm whether your generator requires a vented tank before selecting
• Use the included petcock and fittings to reconnect fuel lines securely

Who is this for: The JJing 7-gallon universal fuel tank is aimed at owners and technicians replacing damaged or corroded gas tanks on portable generators rated roughly 5000–10000 watts. It suits DIYers who can measure and match mounting patterns, service shops that handle multiple generator brands, and anyone who needs a ready-to-install aftermarket tank with common maintenance parts bundled. If you require a vented reservoir or exact certified 7.0 gallon capacity, choose a different model; otherwise this tank offers a practical, multi-brand replacement option with included hardware to get a generator back to reliable operation.
