Replacing fuel lines on a 2000 Bravada involves dropping the gas tank and replacing the damaged or worn out lines. Here are the steps involved in dropping the gas tank and replacing the fuel lines:

1. Disconnect the negative battery cable to prevent any electrical hazards.
2. Remove the fuel pump fuse or relay to relieve the fuel pressure.
3. Raise the vehicle using a jack and jack stands and secure it in place.
4. Locate the fuel tank and disconnect the fuel lines and electrical connections from the tank.
5. Support the fuel tank with a jack or stand and remove the straps or bolts that hold it in place.
6. Lower the fuel tank and remove it from under the vehicle.
7. Inspect the fuel lines and replace any that are damaged or worn out.
8. Use the appropriate fuel line connectors and clamps to replace the fuel lines.
9. Install the fuel tank and reconnect the fuel lines and electrical connections.
10. Reinstall the straps or bolts that hold the fuel tank in place.
11. Lower the vehicle and reconnect the negative battery cable.

As for the tools needed, you will likely need a socket set, wrenches, pliers, a jack and jack stands, and a fuel line disconnect tool. You may also need a fuel line repair kit if the damage is significant.
It is important to consult a repair manual or seek the help of a qualified mechanic if you are unsure about any step in this process. Additionally, be sure to follow proper safety precautions when working with fuel and fuel lines.

Yes, the gas line connector needs to be replaced. This is probably why it came disconnected.

It is never a bad idea to do so. If the unit has some years on it, I would say yes. Inspect it, and if it is still nice and white, keep it. If it isn't, I would replace it.

The thermostat probe on most residential water heaters is part of the gas valve. The thermostat is a non replaceable part of the gas vale and if your t-stat is bad you will need to replace the gas valve also.
This is generally not a very hard job just start off by shutting gas supply valve to off position.Disconnect main gas line to burner,line to pilot light, and thermocouple from gas valve. Remove pipe fitting from gas valve and use large pipe wrench to loosen gas valve.
Before you loosen gas valve you will need to shut water supply off and drain water from tank.MOST WATER HEATER GAS VALVES ARE PRETTY STANDARD ITEMS AVAILABLE AT MOST HARDWARE STORES. Just make sure you purchase valve for the type of fuel you have,such as l.p. or natural gas.Remove gas valve by turning counterclockwise. Use teflon tape or pipe joint compound on all threaded connections for reassembly. Hook up gas line,burner supply line,pilot and thermocouple lines. Refill tank and check and check for leaks. Light pilot and turn gas control to on. Set to desired heat setting . Also check all gas fitting for leaks. Good luck. Thanks

They get replaced all the time. The "new" gas with ethanol tends to deteriorate them more quickly nowadays. Small engine repair shop has the fuel lines you need. Repairing them is not done.
If you have the Craftsman trimmer, just ask for about a foot or two of each of the 2 different size lines. They are called "Tygon" fuel lines. Runs about a dollar/foot for the stuff.

There are two connections on the carburetor. One is the inlet and the other is a return, Check closely.

Gas tank drop to replace rear lines. Pretty major job all around. If you want a good deal on used lines sets look at ebay "stores" for "s10warehouse". He has several good used line sets cheap.

You need to disassemble the case to get to the fuel tank. Pull out the plug fitting and replace the internals with new factory grade parts.

I need to replace the gas filter in a featherlite weedeater 18cc. it rotted off and I dont know what line it goes on? is the other gas line a return gas line?

No biggy, you need to buy the same size fuel line tubing, preferably from the dealer, and replace it by undoing the tubing fasteners, little clips you undo with a pair of pliers. Before doing this, make sure you cut off the fuel line valve which should be right under the gas tank, if none, empty the gas tank in a seperate container. Good luck.
