SIP Medusa Tank Cap with fuel extender

This is a filler cap for a SIP Medusa Ti-1002 Inverter Generator. It features a Johnson/Evinrude Outboard fuel connector to hook up an external fuel tank to extend the run time. This only works if the external tank is at least level or higher than the build in fuel tank and the fuel pump in the generator is in good condition.

I have printed this in PC (Polycarbonate) which in my tests has withstood the petrol very well so far, tests with ABS showed that is will soften after only a few hours.
