When we turn the gas on at the gas tank, gas leaks out from the hose on the carb. If the motor is idleling the gas continues to slowly leak. If the motor is being ridden it does not leak. The more you are on the gas the less it leaks.
If you turn the gas off at the tank it stops leaking.

turn off fuel valve if still leaks its between valve and the tank should be two lines from tank to valve or tank itself or even valve --if stops then leak from valve to carb ---either way need to remove valve knob and side flaring to access area
New carbs aren't known for leaking unless you had it open and altered some thing. A float can get stuck if you let it sit without using it. Should put stable in your tank and run it so thestable gets into the carbs.
Check above the carb for a gas leak from the gas hoses and check the gas tank. They may be running down onto the carb and just appears like the carbs leaking
These type of fuel shut offs do not have a manual off position. They are automatically operated by engine vaccuum when working properly. They have malfunctioned and allowed fuel to overflow into the airfilter box(the black box) untill repair time use a long piece of hose to connect the large outlet of each shutoff to eachother or plug the end of two short pieces. The carbs have a drain screw on the very bottom of each facing left , right or straight down. you could also drain the carbs however once the fuel supply is cut to them they should not leak any further. Leave the carb fuel hoses from the tank disconnected. You should drain the tank by siphon and the residual gas that is already in the air box can be drained from the hose on the bottom of the box. This is a mess but once you get all this drained it should stop leaking
1. remove the hose from the carb and see if the petcock is shutting off the gas and if not clean, repair or replace the petcock. 2. look in the tank and see if it has rust in the tank even a small haze of rust as rust will cause the needle and seat to stick in the carb and make the gas leak. If the gas tank has a lot of rust it may need a tank rubber liner kit added or even a new tank to stop the leaking. 3. if the bike has been sitting for a while it may have trash in the fuel system(carb/petcock/tank). Rust or any trash can cause a leak. Properly clean out the carb and fuel system and add a new filter when done. 4. Improperly adjusted or bad needle/seat or float in the carb will cause continual leaking. Replace the needle/seat/float and adjust the new one when installed. Check your service manual for float adjustments.
hi, i have a 1987 polaris trail boss 4x4 was riding and gas was leaking from the under side front of gas tank, is there a hose from the carb there? Anyway when i noticed the gas leak we stopped and it slowly ideled down until it died and then would not start.
I have spark pulled carb and cleaned i get gas.
can you help?
This may have been caused by the OPD valve in the gas tank and the way it was turned ON. It may or may not be correctable. However, lets give this a try.
1. Turn the gas tank valve OFF and disconnect the hose from the tank.
2. Wait 5 minutes and reconnect the hose to the tank.
3. Open the tank valve VERY, VERY SLOWLY (Slow motion, slow).
4. Once the tank valve is fully open, check the regulator for leaks. If none are found proceed to the following. If there is a leak STOP & turn the tank valve OFF. And proceed to the last paragraph. Light the burner farthest from the tank first and set the burner
control knob on HIGH. Does the flame height look correct for being set on HIGH? If so, light
the remaining burners the same way. Do all the burner flames look correct? If so, you solved
the problem. Remember, to always open the tank valve Very, Very Slowly.
If that didn't solve the problem, you will need to replace the grill's
Hose/Regulator Assembly. It runs about $30.00 at any home center or
hardware store that sells grills & accessories. After you replace it,
turn the tank valve ON Very, Very Slowly.
I hope this helped you and thanks for choosing FixYa.
If all you need to know is how to connect the grill's hose to the tank, I think I can help you.
Properly set the LP tank in the grills tank holder. If the tank has a plastic cap over the tank valve, remove it and discard it. Connect the hose to the tank by attaching the hose's connector coupling to the tank valve. Align it properly and turn the coupling counterclockwise to attach it to the tank valve. Once you have the coupling as tight as you can by hand, turn the tank valve on the top of the tank ON VERY, VERY SLOWLY (Slow motion, slow). Once the valve is fully open, check the coupling for leaks. Soapy water brushed or sprayed on will be fine. Look for bubbles around the coupling, where it attaches to the tank valve. If you don't see any bubbles that grow in size, then there are no leaks. If you find a leak, turn the tank OFF and disconnect the hose slowly. There will be a whoosh of gas, but that's normal. Reconnect the hose coupling again and follow the same procedure above.
If everything checks out the first or second time, you're ready to go. Happy Grilling!!
sounds like u either have a loose hose or a broken hose look for hose going from gas tank to engine check for any breaks or loose connections if you find nothing than check carb for any leaks if broken hose u can replace it for around $2.00 to $10.00 depending on how much hose and clamps u need if it's not the hose then it could be carb-check bottom of carb and sides for any gas leaking out do all this with motor turned off once u find problem-start engine and see if u have any other leaks
