I lose all fuel by the next day with out use. I think the fuel tank has a crack in it, couldn't find it just by looking. If I change out the fuel tank, what other parts should I order?
Roman For model number PB-201 - January 3, 2024

We show the compatible tank as part# A350002541, the fuel tank cap as part# P100006640, the fuel tank vent is part# A356000031, and the vent cover is part# 13132840630.

Removed fuel lines from air purge body assembly. Removed the purge bulb retainer. Removed fuel line grommet from fuel tank by prying out with a screw drive. Inserted new fuel line, fuel vent line, and fuel return lines in new fuel line grommet. Inserted new grommet with lines into fuel tank by carefully using a screw driver to push gr ommet into the opening. Then inserted fuel tank vent into the vent line. As a precaution, I changed out the air purge body assembly. Attached the fuel line and the fuel return line to the air purge body assembly. I had taken a photo of the connections before dis-assembly to be sure I got the lines back in the right places. Installed the new purge bulb and reinstalled the purge bulb retainer. Hedger now runs great.

The Echo trimmer needs a fuel line grommet, the old one was cracked. The trouble shooting list on ereplacement web site clearly indicated this problem and solution. The new grommet solved the problem. For shipping cost, also order and replace vent tube and fuel tank vent.
The Toro trimmer had the same problem, but grommet is no lon ger available. Had to order a new fuel tank. I was happy that the new tank comes with fuel filter and fuel and vent tubing already installed permanently on the new tank. No grommet is needed in the new fuel tank. So the purchase price is a good value. Just plug the fuel and vent tubing to the engine, and it runs like new!

Was leaking gas

Gregory from Cleburne, Texas

Difficulty Level:
A Bit Difficult
Total Repair Time:
30 - 60 mins
Tools:
Screw drivers
Removed the cover over the gas tank.
Disconnected the fuel lines from the carburetor.
Removed the gas tank from the edger and was able to see the gas tank was OK.
My problem was the fuel return tube. The tube is vinyl and was loose in the grommet.
The new grommet has metal sleeves that the old grommet doesn\'t. Bec ause of the metal sleeves, the hoses were hard to install. Finally on the last hose, I put some light grease on it and the last hose went in a whole lot easier. I wish I had thought of that sooner. Actually, I should have used some of the oil you mix with the gas. I\'m not a full time mechanic.
I installed the grommet in the new tank (might as well use the new tank) and reinstalled the tank.
I reconnected the fuel lines to the carburetor.
I reinstalled the cover.
I filled the tank with gas and the edger started right up and I no longer have a gas leak.
If you experience a gas leak, try sliding all 3 hoses up and down. They shouldn\'t move. If they do, you might have an old grommet like I did without the metal sleeves. My vinyl fuel return hose was also deformed were it went thru the grommet causing my gas leak and the edger harder to start.
I hope some of this is helpful to somebody else. I\'m not an author either.
