No gas coming to carb fuel filter good engine runs while sraying gas in carb

Onan engine? If so, check your fuel pump. It will be located on the engine cowling. You'll see 2 fuel lines, one on top and one on bottom. These are the fuel in/out lines. The line you WON'T see is the vacuum pulse line that hooks to the rear of the pump assembly behind the cowling. This line operates the pump via a vacuum pulse created by the engine.
You can remove the pump mounting screws and the pump will pull away from the cowling a short distance exposing the vacuum pulse line. Make sure it's attached and not dry rotted. If the engine has set up for any extended period, there's a good chance the pump gaskets are "glued" to the pump chambers (internally) by bad gas and not allowing the vacuum to pump the fuel. Onan has (when I was working on them) kits for these fuel pumps and I've installed them successfully, but it might prove to be somewhat tedious if you're not well versed in kits of this sort or not extremely mechanically inclined. But if memory serves, a new pump was priced within reason. Good luck.
