Gas line fitting for yard car

[true temper]

I noticed gasoline dripping out of my yard car, it has a plastic gas tank, well after 30 years or so the rubber grommet that seals the fuel supply line gave out.
plastic tank is smooth with a 3/4” hole. I made a new fitting with a couple of Orings to seal it up

I keep a few of the John Deere plastic gas tank grommets in stock - about $5 each. Your solution is certainly more elegant and those washers look like the washers on auto shocks.

Your o-ring contraption should be on the inside of the tank. Is a stop machined into the contraption? Is the outlet located in some sort of sump? Is your part made out of stainless steel? Also, resist the temptation of over tightening the nut (unless you machined in a stop).

I didn’t have any idea where to find a tank grommet.
No need for stainless fitting.
outside of tank was smooth, inside of tank was rough, worked perfect.
only worry about over tightening is twisting off the hollow stem.

Being a gasoline tank, there is the inevitable water in the bottom of the tank. Another worry about over tightening is the crushing and subsequent failure of the walls of the tank.

If it has no return, one of the best mods I have been doing lately for things like this is convert the line to a "outboard motor" type fitting. Then you can use just one fresh can of gas in a boat tank from one seldom used machine to the next. I did this with my last plow truck too and it worked a treat! No more bad gas because something isnt being used enough. Also great anti theft system.
