Fuel Tank Has Been Invaded

[bartles]

Working on a LT1045, new to me. I was having fuel feed issues so after all the usual suspects were cleared, i.e. carb, fuel pump, flow from tank(trickle) I peeked inside the tank with my borescope and found trash from the fill cap sealing gasket and a fuel nozzle! This was a first for me.

I really appreciate all the help from the forum this year!!

Happy Thanksgiving,

That is a commom problem with these mowers. I see it a lot. Looks like they would use a better material instead of rubber which dosen't hold up to fuel very well.

Ethanol absorbs into and dries the seal material because it is not designed for it. For the overall machine and soft fuel lines, I recommend you spend the extra money and buy only non-ethanol fuel. Ethanol fuel collects humidity which can be very bad for the carburetor internals as well.

Your current tank can be removed and cleaned out, then buy a new cap. I also suggest you replace the fuel lines with a quality brand such as Gates. Don't forget the inline filter.

Last but not least, check the inlet of the pulse fuel pump to make sure no debris got that far.
