If its for the fuelcock, i would replace the fuelcock with a manual one. Check if you have fuel to the carb if not you know you need a petcock.

SOURCE: mass flooding piston cylinder

This sounds to me like a carb float being stuck open. Turn off the gas and drain the carb. Next, turn the gas back on and sharply tap the float bowl with the plastic handle of a screwdriver as the fuel bowl refills. The goal here is to vibrate the float to free it up. If doing this process a couple of times does not free the float I would remove the carb and clean it with a spray carb cleaner. Be sure main jet and float needle are clear. Clean the air filter then re-mount carb. Next Remove the water trap bowl at the bottom of the petcock, (gas valve). Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Install an inline fuel filter. Turn the gas on, wait a moment for the float bowl to fill with gas then give it a try.

Please rate this solution. Thanks!

SOURCE: gas leaking from hose that is under tank that is not for gas flow

is it an overflow from the carb? gas will only be in one of 2 tubes and they are the fuel line from the tank and the carb over flow. unless you have an electronic fuel pump then tubes go from tank to pump to carb. if its coming from the overflow then you are getting too much fuel into the carb float chamber. you may have a sticky float. thy getting some Berrymans B12 fuel additive and putting double the doseage in the tank. run engine til hot then leave it to stand overnight. this should break down any gum/varnish that has built up in the system

has this been in storage thru winter?

I have a, sanborn black max compressor builds up to about 30psi but won't go higher. will hold that when shut off. couldit be a check valve?


If it were the check valve, (safety release valve), you would hear the air escaping from the safety release valve. You have an air leak somewhere. A small leak in the system will keep the compressor from building pressure. If you turn the compressor on and feel around the ends of the tube that leads from the compressor cylinder head to the tank (be careful... it will be HOT) you may feel air escaping from the tube connector at the tank or the connector at the compressor cylinder head. If that is the case, tighten the connectors at the compressor head and the tank. If the connectors still leak, you will need to remove the tube and replace the packings (gaskets) at each end of the tube. Also check all of the hose connectors for leaks, and check the hose for damage that may cause an air leak. If you remove the air hose from the compressor and run the compressor you will be able to tell if your problem is in the hose or hose connectors or the compressor-to-head air tube.

Ingersoll Rand Triple play air compressor won't build pressure in tank


Jason:

while the compressor is running, feel around the fittings at each end of the air tube that runs from the compressor cylinder head to the tank. You may feel air escaping at one or both of those fittings. Tighten the fittings and check again. If air is still leaking from the fittings, you will need to remove the tube and replace the packings.

My 93 Honda CBR600 TURNS BUT Wont start. it started yesterday but was leaking fuel through the fuel lines so turned it off n took gas tank off n replaced hose clamps n put back together n now it wnt start....


When you put the fuel hoses back and refitted the tank, did you make sure the vacuum tube to the fuel tap was reconnected ?

The fuel tap has a vacuum connection in order that the fuel is automatically cut off when the engine stops - the tap has on-off-reserve manual settings, but this is overridden by the vacuum. So, even if you have set the tap to "on", if the vacuum hose is disconnected/blocked/leaking, no fuel will reach the carbs.

The vacuum hose is about half the diameter of the fuel hoses and connects to the smaller spigot on the tap, and either the number 1 or 2 cylinder vacuum take off point on the carbs.

I have a 2006 F250 which I have lots of aggravating problems with trying to fuel up. No matter which gas stations or method of inserting the nozzle into the fill tube I use, I am frustrated by the time it...


where the filler neck goes to tank didnt it have seperate tube which is vent or with filler neck hose off at tank look inside tube for another hose it is vent hose take fuel cap off and blow air from tank end towards the filler cap area we have had two ford vehicles lately in our shop when we blow shop air backwards thru hose several little round pieces of foil off of fuel injector cleaner bottles somehow they had become lodged in vent line and one customer had vehicle towed from gas station because they were on empty and would accept no gas you may want to check this doesn,t have to be cleaner bottle tops could be any sort of debris but ours came flying out of fuel cap when when blew air thru you could pump gas with handle all the way down she was happy

How do you replace the egr valve in a 1997 chrysler concorde lx


Chrysler Concorde 1993-1997 3.5L MFI 6cyl
Exhaust Gas Recirculation System
Operation

This system reduces the amount of oxides of nitrogen (NO x ) in the exhaust by allowing a predetermined amount of exhaust gases to recirculate and dilute the incoming fuel/air mixture. The diluted air/fuel mixture reduces peak flame temperature during combustion, which in turn inhibits the production of Nitrogen oxides. The principal components of the system are:
- EGR tube (connects a passage in the intake manifold to the exhaust manifold)
- EGR valve
- Electronic EGR Transducer
- Vacuum hoses


Component and System Testing
  1. Check the condition of all of the EGR system hoses and tubes for leaks, hardening or kinks on the rubber hoses. Repair and correct these conditions before proceeding any testing.
  2. Be sure that the hoses at both of the EGR valve and EGR valve control are connected to the proper fittings.
  3. Be sure the electrical connector is firmly attached at the valve control.
  4. To check the EGR system operation, connect the DRB III scan tool or equivalent to the 16-way data link connector. The data link connector is located on the lower edge of the instrument panel near the steering column. Follow the scan tool instructions.
  5. After checking the system with the DRB III scan tool, proceed to the EGR valve leak and control tests, then repair as necessary.

Loosen, but do not remove, the EGR tube to intake manifold screws

The EGR valve attaches to the rear of the right cylinder head.
  1. Remove the vacuum tube from the electric EGR transducer solenoid. Inspect the vacuum lines for cracking, poor seal due to hardness, or other problems. Replace with new hoses if necessary.
  2. Remove the electrical connector from the solenoid.
  3. Slide the transducer up and out of the mounting bracket.
  4. Loosen, but do not remove, the EGR tube to the intake manifold screws.
  5. Remove the EGR tube lower screws at the valve.
  6. Remove the EGR valve and transducer.
  7. Clean both gasket surfaces and check for any signs of leakage or cracks. Replace the components if any such damage is found or if the valve fails the tests.

To install:
  1. Loosely install the EGR valve and a new gasket onto the cylinder head.
  2. Using a new gasket, attach the EGR tube to the valve and tighten the screws to 95 inch lbs. (11 Nm).
  3. Tighten the EGR tube to the intake manifold plenum screws to 16 ft. lbs. (22 Nm).
  4. Tighten the EGR valve to the cylinder head screws to 16 ft. lbs. (22 Nm).
  5. Reconnect the transducer solenoid to the vacuum fitting on the manifold.
  6. Slide the transducer into the bracket.
  7. Reconnect the vacuum lines and electrical wires to the EGR transducer.

Original gas tank replaced because of holes. New


It sounds like the new gas tanks do not have a breather fitted to them.

As you remove gas from the tank it needs to be replaced with air if not it creates a vacuum and natures way of filling a vacuum it to compress the space it is in

Fill a plastic soda bottle with fairly hot water , give it a minute then pour the water out and quickly screw the top on , watch the effect , that is your gas tank

There is either a metal or rubber tube or even a vent in the filler cap to allow air in

You did something to alter that ?
