Off topic,
But back in the early 70's I had a problem with an old Chevy panel truck
that drove me crazy for six months. I bought the old Chevy from a fellow,
cheap. He warned me that it would not run below 1/4 tank of gas. Sure
enough
he was right. I found it would stall at a little less than a 1/4 tank
showing on the fuel gauge. I could restart the truck and run a short way,
but it would stall again within a minute. When I filled the tank
everything
was fine until I went below 1/4 tank again.
Over time I replaced everything in that fuel system except the gas tank to
no avail. When I finally pulled the tank there was a ping-pong ball in the
tank that apparently would get sucked up against the fuel line when the
tank
got below a quarter full.
