Gasoline is leaking out...

Gasoline is leaking out of tank on my Quantum 12F-802

Mechanic's Assistant: I'll do all I can to help. How long have you been dealing with this?

Engine that is on my Ex-cell gas pressure washer.

Mechanic's Assistant: What's the make and model of the pressure washer? And can you guesstimate how old it is?

The washer was working fine a few years ago. I was planning to clean my courtyard, fill the tank with gasket it all leaked out.

Mechanic's Assistant: Do you plan on doing the work yourself?

Its a Ex-cell 1750 psi model no. EXWGV 1721. Its at least ten years old but was used sparingly

Mechanic's Assistant: Anything else we should know to help you best?

It doesn't start easily. I have to puy gas in the spark plug hole for starting.

The unit was in the garage for a year or so after the last use. The last use went fine with no problems. I wanted to water

Is the gas leaking from your fuel tank or from your carburetor ?

Technician: Donald, Small Engine Technician replied 5 months ago

If the gas is leaking from your fuel tank, you will need to replace your fuel tank. If it is leaking from your carburetor, you float could be sticking.

carburetor. Gas seemed to be leaking out of tank. Could it be a line ? All of the gas leaked out of the tank. Jd
