leaking gastank

[Maxwell-8 4,277]

My raider 12 has a plastic fuel tank and it's leaking fuel strait on the battery 

It's a plastic one, and it's leaking where the shutoff valve is. Looks like there is not much pressure and the rubber seal.

How can this be fixed?

 

Can it be tightend?

That rubber grommet should likely be replaced.  Before buying another, pull that one apart and inspect for cracks in the plastic tank.  Then, the grommet is installed and the valve simply pushes in.

Thanks but how do i disassemble it? Just jank everything out?

[Pullstart 62,922]

Yup.  Twist and pull the valve, it’s just got an expanded end to hold it in place.

Looks like someone already tried glueing or epoxy

jip, and it was holding, before i replace fuel lines and twisted to much with it 

now time for the proper fix

On this side of the pond, they are fairly easy to find.  You see the valve has a pre-filter.  If you can find the kit, it might be a better way to go than simply replacing the grommet.

MAXWELL-8 , if the tank is not cracked in that area , LUBRICATE THE SEAL GROMET WITH A LIGHT GREASE , and ensure its sitting in place. rubber to rubber or similar surfaces will not " seat " to seal. having replaced all 3 of my tank seals / valves , it was the light grease film ,that made everything slide and fit in place. just an idea , pete

The tank is in good shape, gone try and find a new gromet set, for now, i used some ptfe-tape to make the grommet expand more, and used a washer beneath the gromet as it apperd to be saging, therefore letting gas leak thru.   and used some grease.

Thanks @pullstart, @peter lena 

Oh, yeah didn't i mentioned time for a proper fix ?

Is there a WH or Toro part number for this?

 

I find this number, but not sure if it's correct, google gives nothing found with it: TORO #772030

77-2030 is the wrong grommet used on small Toro gas trimmers

104047 is the most common one we see but Wheel Horse did not use it until 1974 so yours may be different.

I find it much easier to install if I start the barbed fitting into the rubber grommet up to the first barb, then insert the grommet into the tank, then push the barbed fitting in place expanding the rubber to make the seal.     Of course all parts should be greased before assembly.

I had the same thing happen to me last year. Replacing the fuel lines and as soon as they moved gas started dumping. Bought a new valve and grommet, but couldn't for the life of me get it to seal. 

 

Finally gave up and put an old steel tank on it.

Got grommets and the whole kit on stock if you need it Max

Thanks, on the shopping list, Do you have any idea how long shipping will take?

[Skipper 1,788]

No, but my best guess would be that a week could pass.

Lately it's been a crap shoot  I've got a few things earlier than expected, some when they said, and others, I thought they'd never come.
