Pressure Washer Tank & Container Parts

Pressure Washer Tank and Container Parts

Your pressure washer's tank isn't just a reservoir — it's the foundation of consistent, reliable spray. When tanks crack, seals fail, or fittings loosen, pressure drops and cleanup stops. Whether you're dealing with a fuel tank on a gas model, a water tank on electric, or the mounting brackets that keep everything secure, OEM replacement parts ensure the right fit and function.

Tanks, caps, drain plugs, and gasket sets are built to withstand the specific pressure and vibration of your model. Using genuine parts prevents leaks, maintains proper water flow, and keeps your pressure washer running at full power.

• Fuel tanks (gas PW): Cracked or loose, fuel seeps; filler caps and vent lines included
• Water collection tanks (electric PW): Cracks reduce capacity; drain valves wear out
• Tank gaskets and seals: Water leaks at connection points; O-ring kits prevent moisture escape
• Filler caps and drain plugs: Missing or damaged caps allow air/water intrusion; threaded plugs corrode
• Tank mounting brackets and hardware: Vibration loosens bolts; replacement hardware secures tank to frame

Pressure Washer Tank and Container FAQs

What causes pressure washer tanks to crack or leak?

Pressure washer tanks fail from thermal stress (rapid heating/cooling), impact damage, or corrosion of fittings and drain plugs. Plastic tanks degrade faster in UV light and cold weather. Metal tanks rust from inside if water isn't drained after use. OEM replacement tanks are engineered for your model's operating pressure and temperature range — aftermarket tanks often fail prematurely. Check your model number to find the exact tank assembly for your machine.

Can I replace just the tank gasket instead of the whole tank?

Sometimes. If the tank itself is sound but seals around the filler cap, drain plug, or inlet fitting are weeping, gasket kits and O-ring sets are available and much cheaper. However, if the tank has visible cracks, warping, or the plastic is brittle, replacement is safer and more cost-effective. Enter your model number — we'll show you whether a gasket kit or full tank assembly is the right call.

How do I know if my fuel tank needs replacing?

Gas pressure washers won't start reliably if the fuel tank cap is missing or cracked (allows water in), the filler neck is damaged, or the fuel line connections are leaking. If you smell fuel around the tank but see no visible crack, the seal may be failing — a replacement cap or gasket often fixes it. If fuel is actively leaking or the tank is cracked, replacement is necessary. Model-specific fuel tanks come with the cap and vent line assembly.

What's the difference between OEM tank parts and replacements?

OEM tanks are designed for your exact model's pressure rating, water flow, and mounting points. Tanks are cheaper but often don't fit properly, causing vibration, alignment issues, or pressure loss. We carry OEM tank assemblies for, and other brands — finding your model number ensures you get the right capacity and connections the first time.

Filter Pressure Washer Parts by Your Model Number

Skip the guesswork on fit by starting with your pressure washer's model number, usually found on a label attached to the frame, near the engine, or on the pump housing. Check the sides and rear of the machine, and clean away dirt if the label is hard to read. The model number identifies the complete pressure washer, not just its tank, hose, pump, or another individual part. Enter that number in the model number search, and the catalog will narrow to parts made for your unit across every part category. You can then compare the available options with confidence instead of sorting through parts for other machines. That means fewer wrong orders and a faster repair.
