Hi Guys,


Have a T758ES powered by a Kohler K181 engine that I've had for a few years and has always ran well. Last year it quit running and haven't had a chance to look into it until now.


I've diagnosed the issue being the fuel pump that I'm not even sure if it really needs as the issue as gas comes out of the line to the pump, but doesn't come out of the pump. 


Firstly, is the fuel pump even necessary? (I just ask because the tank is above the carb and I would think gravity would provide enough fuel flow.)


How complicated are these little pumps? Is it worth looking into rebuilding it?


Is there a recommended replacement pump for these engines?


Thanks in advance for any input/education. Rob

It may just need a new rubber diaphram

I don't know if the T758ES needs it or not, but I have the same machine, and mine is just gravity fed.  It seems to run fine, but who knows, maybe I'm missing out on something.  It runs good enough for me though.

I also have a T758e that I have cleaned with success, my second option was to bypass the pump. If you do bypass the pump make sure the filter is for gravity feed and please let us know how it works. 

good luck
