Is it the small diafram for the excelarator pump? If it is then you have a hole in the diafram and it will need replaced.

Vents re not switching from window to ac vents tookout glove compartment and the diafram rod wasn't moving I was able to move it but it wouldn't stay open any suggestions ?


Sounds like vacuum leak, bad check valve, or faulty actuator. Test vacuum at actuator first if possible. Vacuum check valve is common failure part.

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.

5. Plugged bowl vent.
6. Fuel level (float chamber) too low.
7. Restriccted fuel supply passages.

P0442 - Evaporative Emissions System Leak Detected (Small Leak)

P0455 - Evaporative Emissions System Leak Detected (Gross Leak)

This diagnosis detects leaks in the EVAP purge line using engine intake manifold vacuum. If pressure does not increase, the ECM will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition. The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.

Causes:
- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve
- Leak is in line between intake manifold

Solutions:
- Re-tighten or replace fuel tank filler cap
- Replace damaged or leaking EVAP canister
- Replace damaged or leaking lines.

Gas in oil tank after bike sat for two weeks.


If you have gasoline in the oil tank after sitting for two weeks, you probably have a bad petcock. In 1996, Harley went to a vacuum operated petcock. They are notorious for leaking fuel. Additionally, you have a problem in your carb. Either the needle and seat are not sealing and leaking fuel into the carb or the accelerator pump diaphragm is bad causing the fuel to seep into the engine.

Once the fuel seeps from the carb into the engine, it will get past the valves, and the rings on the piston and into the crankcase. It will sit there until the engine turns over. At that time, the oil scavenger pump will pump it into the tank.

I suggest you replace your petcock with a high quality manually operated petcock such as a Pingle, have your carb gone through by a competant mechanic, and change your engine and primary lubricants.

Good Luck
Steve

Oil leaking around engine


Oil leak can be attributed to several factors.
1. Gasket failure.
2. Uncontrolled Crank case pressure Failure.

RECOMENDATION:
Tighten both the valve cover and oil pan bolts.
Replace the Positive Crankcase Ventilation Valve and vacuum line.,

INFO: PCV
This is a valve causes a negative vacuum on the engine while its running, As to say if it had a leak in a valve cover it should not be leaking while its running, only when the engine it turned off.

Hope this tip guides you in the correct direction to solve this problem.

2000 F250 7.3L T.Diesel leaks fuel from under filter + no a/c


Yes directly in the rear of the fuel filter housing there is a yellow valve that is used to drain the fuel/pressure from the filter housing. I personally have replace several of them. They are a little pricey at around $60.00 but includes new o-rings. What will happen is if the valve goes bad it will dump fuel on the p.side next to the engine block, as there is a steel line that hooks to the rubber adapter to the valve. With it running you should be able to see it very easily. If your leak isn't located there, the rubber hose may have come lose from the valve and be dumping fuel into valve of the engine and possibley onto the turbocharger. I would check there first, and if not i would check the fuel filter housing its self. There is an o-ring at the top that could have possibley detoriated or been pinched. Have you had this housing apart recently? Also another mistake in maintenance of the 7.3Ls is the over tightening of the plastic cap for the filter. Let me know how you make out, and we can diagnois farther.
