Bogging down problem

So I ran out of gas and then added the can I carry bc like most my fuel gauge doesn't work. Got that in and it started right up. I start driving and seems to be doing just fine then all of a sudden it just bogs down. I hit the gas and it bogs then backfired. I got back to work turn it off. Then I go to work for a few hours. When I get back to the jeep it fires right and goes good for like 3 miles then starts bogging again. So I limped it home. Trying to figure out what it is and how to fix it. Any help is appreciated.

When you ran out, you probably sucked up dirt, rust, and other nasty stuff from the bottom of the tank.
It could have choked off the screen on the pickup tube in the tank, but normally fresh gas will flush it loose.
The fuel filter definitely needs changed though. I'd bet if you take it off, and dump it out into a paper towel, all kinds of nasty stuff will come out.
That's why it bogs and backfires,the carb opens up but it can't get enough gas.
It probably idles fine, and runs fine up until about 1/2 throttle if you ease into the throttle????

How old was the gas?
Sounds like water in the fuel.

You are correct on the idling and running fine until 1/2 throttle.

A new fuel filter is under $10. That's where I would start.

Replaced the fuel filter, wasn't that. Took the carb off and blew air through all of it. And also blew out the lines. That cleared whatever was blocking the jet and now it's working normally.

I hope not. What's a good way to clean the inside of the tank?

I don't have much experience but my guess would be to drop the tank, drain it and blow it out with compressed air. Look inside and see if it's rusty. I would suggest possibly recoating the inside while you have it down. Just did this to my tank and it wasn't that bad. Then again my jeep is in pieces so it was easy to drop the empty tank.

The only way is to drop it out. It should take 15 to 20 minutes depending on rusty bolts.

If the tank is in good shape then it is agood time to check out the fuel sender and replace the hoses above the tank, they tend to split and suck air.
