Hi,
First time poster. Usually I can find the answers I need in a search but no luck this time.
I have a 2014 Cab & Chassis F-350 DRW 6.2 that I'm trying to remove what appears to be an aux. fuel port on the sending unit. It has a yellow clip that will slide about 1/4" away from fitting cap? will not come off. Anyone know the what why & how of this yellow fitting.

I'm trying to power a 9.0 hp. honda from the chassis tank rather than the little fuel tank on the Honda. I do know that I will need a small fuel pump and I have that covered.

Thanks,
