You have fuel injection? If so, no reserve AFAIK. In the carb version, the gastank fuel petcock is the fuel reserve switch, the lever's normal position is straight down, reserve position is straight up, off is sideways.

The fork oil is a very specific job needing a manual and a special tool, I don't want to insult anyones mechanical knowledge but if you have never done it before, best to take somewhere else. Engine oil on the other hand is easy, the drain tube to any softail is on the right side by where the frame meets the swing arm, has somekind of plug in it. Start and run bike for a little while, long enough to get it warm but not hot. Remove fill plug and then remove plug in drain line. Using a peice of cardboard or something put in between filter and frame , directing the oil to your drain pan instead of where ever it goes. Put 1 qt oil back in (after everything is reinstalled) start the bike and make sure the oil light goes out, when it does shut bike off and fill to the point that when it is standing upright you get a little oil on the tip of your finger, over filling may result in loss of oil cap from pressure (been there)

Harley fuel valve diagram

The fuel supply valve is a vacuum operated valve under the left side of the fuel tank and it delivers fuel to the carburetor when the handle is turned so it is pointing up in the vertical position (ON) and vacuum is supplied to it from the carburetor. The fuel supply is turned OFF when the handle is in the horizontal position and when no vacuum is supplied to the valve from the carburetor. There is a RESERVE fuel supply and it is operational when the handle is turned to point down. IT SHOULD BE TURNED OFF when the engine is not running because if it is not it is possible for fuel to drain into the engine, dilute the engine oil and
cause engine damage.

Replace petcock in 2000 heritage

I replaced the factory petcock on my 2000 FXDWG due to a friend having his stop working. The factory one is vacuum operated. If the diaphragm leaks it won't let fuel go to the engine.

You will probably have a bit of fuel leak during this so don't do it near any source of flame or ignition. Keep rags or an old towel handy and I recommend a fire extinguisher just to be safe.

Just drain the tank thoroughly into a container you can seal like a regular gas can, not an open pail. An open pail will allow gas fumes to spread out and they can be deadly. Turn the valve to off, and remove the hoses.
One for the gas and one for the vacuum.

Remove the factory petcock by turning the large nut that pinches it to the tank. Now you can slip it down out of the tank. There is bound to be some gas dripping off the strainer so expect it.

If you are replacing it with another factory petcock just do everything in reverse making certain the hoses have a good seal.

If you are installing a manual valve without the vacuum function, you will need to plug the vacuum hose or the engine could run lean and overheat. Make sure that new valve has a fuel strainer on it to prevent junk from going to the carburetor.

I recommend putting only about a gallon of gas in to check for leaks. If all is well, fill it up and go for a ride.

Note: If the reserve tube is shorter than the one on the factory valve you will not have as much fuel in the tank when you have to switch to reserve. That happened to me. My factory valve would make me switch to reserve when I had about 30 miles worth of fuel left in the tank. The new one would only leave me about 20. So beware of that until you learn where it hits reserve.

I just got a 1996 harley hertiage softtail--does it have a reserve tank valve? since ther is no gas gauge?

If your bike does not have a fuel gauge it's probably not fuel injected either. If this is the case, you should have a reserve setting on your fuel petcock unless it has been changed. Look closely at your petcock. It should have "on", "off", and "res" on it somewhere but the letters will probably be pretty small.

The '96 models were the first model to have the vacuum operated petcock and they were notorious for giving problems. Your petcock may have already been changed due to this. If not, I'd recommend installing a high quality manual petcock like a PIngle. They aren't cheap but it beats being stranded with a full tank of fuel in the tank but none in the carb.

Good Luck

Considering how tricky the fuel sending unit is to remove for some people Im gonna reccomend you take it to the dealer simply because even seasoned techs break things in the tank
