1864 Fuel Gas Tank Removal -leaking bungs
 

Good day,

Thought I would ask the fine peeps here about this issue.

1864 with CH18...

- Had fuel line blow on left side, under rear fender. Easy fix - replaced the fuel line.
- Ran fine for an hour, then the Fuel Bung, valve, whatever on the rear right side is now leaking - it is definitely the rubber bung...

Anyway, gonna buy these:

And replace both of them. So, couple questions:

1) - Do I have to remove the tank? Looks like enough room down there with the rear tires off...
2) These bungs - I just rip the old ones out, put a little grease on the new ones and push them back in the tank? Then I push the valve into to the bung?

Thanks for the help.

Remove both valves, and bushings (bungs). Reverse your steps, to install.

Use #2 Permatex instead of grease.

Consider replacing the one around the fuel level sensor as well
Good time to flush the debris out of the bottom of the tank and run a pipe cleaner through both shut off valves....

The tank is not that hard to remove. Since your there I personally would
pull the tank, make it spic and span, replace bungs and fuel lines and never
have to worry about that variable again.

Update.

Parts finally came in last week.

Very easy to replace these bungs -what's NOT so easy is replacing the main fuel line from tank to engine (Fuel filter).

Half the mower would have to come apart if you tried to do this without a little trick...there are 2 steel hangers that hold the fuel line to the frame, right underneath the drive shaft...and the 1st hanger up near the steering wheel? I see no possible way to remove that without taking 1/2 the lawnmower apart...here is the trick I did..

I removed the 2 hangers that held the wire harness - this harness runs on top of the fuel line you need to replace. I pushed the wire harness up and out of the way. I then hit the fuel line hangers with an impact - just to loosen them up so the old fuel line had some play when you pull on it...I then liberally sprayed WD40 on those hangers and the old hose...I then took an old pen I had, removed the guts, and cut about a 2" section off - I then pushed one end on the old hose, up near the fuel filter, and pushed the other end on the NEW fuel line - to join the old fuel line and new new fuel line. I then taped with Electrical tape, about 2 wraps will do - you don't want too much tape to be used, as this will swell the diameter and make the next part impossible...so, with those 2 lines connected, I then pulled the new line (from back of mower) thru the 2 hangers to the back of the mower...

Easy stuff and I did not have to take 1/2 the mower apart.

And above poster was correct - no sense going this far and not replacing all the fuel lines - after 25 years, they were in rough shape.

And the dirt and grime underneath the seat??? I should have took pictures...was unreal.

Thanks for the help.
