Coleman UT400 gas leak

[John Pappa]

I have a fairly new UT400 bought from Tractor Supply in November 2021.  I am second owner and have had it only for a couple of days.  It has 15 hours on it.  I just filled the tank all the way the other day and drove it around a bit.  Last night it started leaking gas all over the garage floor.  This thing still looks brand new and has not been driven hard by me.  I do hear a bit more rattling than I would like but otherwise starts and runs great.  Any ideas why it would start leaking  underneath the chassis?

Maybe you overfilled it. My 2019 has a gasket on top of the fuel tank where the pump is installed. Check all bolts and connectors they're known for not tightening them

I was thinking the same thing.  May have overfill.  Will keep an eye on it and not fill to top next time.

I Whish I had my UT400 out of the repair shop, bought it in October, Engine piston rings failed after Christmas and destroyed the engine, had only 25 hrs on it, had gasoline problems leaking, then oil fowling sparkplug, after that engine wouldn't start.
