Just look at the old hoses. The one with the filter is the pickup line.
I recall some black thing on my Troybilt weed whacker/edger. I think
it really is just a hose connector. No need for a check valve that I'm
aware of. But why they needed that connector, IDK
This guy must have bought the right size ID hoses because they went on
easily whereas mine took a really long time to finally get on the nipple.

That video of a Troy-Bilt TB146 EC tiller shows the black connectors at

For whatever reason there's a third black hose to hose plastic connector
that was sitting inside the gas tank.

Did you look inside the connector? Try to pass a wire through it? Mine was
just a connector, open.



I assume it went on the return line only because it couldn't have been on
the supply line but what good would it do inside the tank except act as a
stop to prevent the return line from pulling out of the gas tank?

I have no idea what the guy did about the gas filter nor why he used a
sharpened chopstick to ream the smaller return line hole which is the one
closest to the engine.

I used a drill bit that I twirled between my fingers for a couple of seconds
to clean out the smaller hole.

The larger hole (further from the engine for the supply line) didn't need
reaming but this video seems to show he used the same hose for both (which
may be the case for my originals too as it's hard to tell their original
size).

On mine they are definitely different size hoses.
