If you have a carb it's not likely you have an electric fuel pump unless a previous owner installed it. This is where and what the pump should look like if it's mechanical.
https://www.high-performance-engines...hp-p/hp40c.htm
If you do actually have an electric pump you should be able to find the wires going to the top of the tank. If you have a fp relay it could be under the doghouse down by the gas pedal. If the relay fails then it defaults to the oil pressure switch. If both fail then the pump won't run.
If all else fails you can buy an inline electric pump and put it inline somewhere along the frame rail as a temporary fix. Also like mentioned in a previous post fill up the bowl in the carb via the vent tube. Start it and see if it will prime the engine. Much better for the engine than giving it a shot of starting fluid.

Hopefully AutoZone sells the relay. We are trying to leave for a camping trip tonight.

Where was the relay?

Would like to see a picture of that "carburetor" without the air cleaner installed...Like Craig 1960 said, electric fuel pump not likely on carburetor unless aftermarket.

I used to have a 1988 Sportscoach Crosscountry. It had a Quadrajet, and an electric fuel pump in the tank. That is why it had the fuel pressure regulator in the gas line by the rear axle on the passenger side.

No meaning to offend - but a Throttle Body Injection (TBI) looks like a carburetor to the untrained eye. The "fuel injectors (two) are at the top with the red colored electrical connectors.
This is a Chevy 454 (7.4L) TBI

In the doghouse, driver side, mounted near the front of it next to another box with electrical wires coming out of it. It's bolted on with two 8mm nuts.
Where is the carb vent tube? I'm not familiar with the carb so I'm not sure what is what on it.

As soon as I get back, I will take a picture for you. It looks nothing like the other picture somebody else linked. It has a primary butterfly flapper and a secondary smaller one in front of it.

I'm thinking you have a quadrajet carb if so it's the tallest round tube in the picture sticking up. Sometimes they are oval shaped but should always be the tallest.

That's exactly what it looks like. Except the tube in the middle isn't angled it is straight with a barbed end on it.

Found out the pump works. Removed the relay and jumpered pink and tan/white wires. Gas came out. Now I need to find out how to fix it. The relay isn't available anymore so for now I'm going to wire a switch into it and turn it on when we start the motorhome up.

Have you tried a salvage yard for the relay?

Glad you got it figured out. You don't need the exact same relay, a 4 or 5 terminal 30 amp automotive relay will work.
