Help needed with fuel line sealant
Posted on 9/20/11 at 8:55 pm

I borrowed a tractor (Ford 7410 HD)
As usual it has problems this time too.
I went out to replace the broken PTO electrical switchs to discover the batteries dead and leaking acid, and the slow but steady diesel leak from the tank. The batteries are being replaced by the owner tommorow.
The fuel leak is coming from a rubber grommet around a fuel line that comes out of the bottom of the full 50 plus gallon tank. With sideways pressure on the fitting I am able to get the leak to stop but as soon as I let go it starts back up.
Is there any sealant that will bond and dry to the rubber fitting and tank to stop the leak? Will I be able to remove it later when I fix it correctly? which of course involves draining the tank, replacing the fitting and adding a thin film of silicon.
I could of course just keep mowing with it and add extra fuel but it may get costly as the calculated drip rate of 1 drop per second is 5 gallons per day.
To top it all off the dang fuel sensor does not work so I have no idea when the tank is running dry.

Gorilla Glue?

Try JB Weld. I've patched something's with it. Never on a leaking diesel line. It's like epoxy and hardens quick. It's cheap so worth a try.
I would quit putting fuel in it. Once low enough that it stops leaking then patch.

Well, of course. Unfortunately I only have the tractor till sunday so I need to get the work done with it and dont have the time to fix correctly between now and then. Once returned (it came to me with this problem) I will go over and fix it there, which is in a shop and not out in a field. And without a fuel gauge I kind of have to keep it partially full. Running a diesel tractor empty is not a good idea, or so Im told.

Drain the diesel in buckets one evening. Patch with JBWeld let sit overnight.

well hell, with a 5 gallon bucket and some cheese cloth I should be able to capture most of the leaking fuel overnight and just count the fuel lost during use as waste.
Then when I am done I can fix it correctly.

so as long as I am not running it when it goes out of fuel I should be ok right? For instance if I catch fuel from the leak in a bucket and then pour back into the tank prior to running I should be good right?

Will be O.K. if it's not beyond the injectors.
