Fuel Problem

From: Carter Sandvik

I have a 1953 Mercury that I purchased, cleaned up and got running. The plan is to sell it to help fund my '58 DeSoto. I'm having a fuel problem. Maybe you guys have some suggestions. I put a new fuel pump on the flathead and stopped a leak in the overflow line. The car starts and runs fine, but if you let it sit for a couple of days, the problem begins. The car starts fine but if you try to back it out of the driveway right away, it will starve for gas and quit. The fuel bowl looks full but nothing is getting to the carb. I then have to prime the carb about three times before the car will start and keep running. Once the car is running and warmed up for a few minutes it will be fine for the rest of the day. I have noticed that when I start the car after it has sat for a few days, if I leave it run for a few minutes before I drive it, I don't seem to have the problem. My son thinks maybe it's the fuel sending unit. He thinks it has rust holes in it. But why doesn't it have a problem once the car has warmed up? By the way, you can see little air bubbles shoot into the fuel bowl every once in a while when the car is idling. Anyone out there have any ideas? I'm stumped.
