Found fuel line from fuel filter canister to fuel bowl leaking. Replaced the fuel line and generator acts as if it is starving for fuel. Help!!!!!!

Do you mean the braided line between the pump and carb?? If that is not leaking, perhaps you disturbed the fuel hose feeding the pump from the pass through fitting on the drawer tray. Those often kink and partly pinch off when drawer is closed giving your symptoms. I replaced with new Tygon hose.

Yes the braided hose. Fuel line behind generator is fine. I unhook the new hose I put on and made sure I had fuel coming to the pump, and if does. I put new hose back on and it acts as though it is starving. Purred like a kitten before I changed hoses. I did notice one of the fittings has a little bit smaller of a pass-through than the compression fitting end. Would this make a difference in flow?

I’m confused with your diagnosis. The braided line is coming from the pump not to it , Slightly smaller is still way bigger than needle/ seat flow at inlet to carb so should not restrict.

Perhaps you knocked loose some old thread compound or dirt by replacing that hose and it has partly restricted the inlet seat of carb.

Sir, I have occasionally have had rubber lines made at places like Royal Brass for brake and fuel lines. I always blow shop air thru the line before installing as sometimes a ball of rubber blows out from shop installing the ends.
