Can;t get gas up to carb

Hi Warwagons,
I thought the same thing, When I talked to the guy at Vans, He put one together at his shop, same gas tank same sending unit. He said it should be pointing up at the 12:00 position, and a little towards the 11:00. I checked mine after that and it is in the same position. Puzzling, I do remember it went in a little hard into the gas tank, had to push on the sending unit as I was putting on the lock ring. almost like it didn't fit well to begin with.
