Question about Harley Davidson XL Sportster 883 Motorcycles

1 Answer

87 sportster fuel line gets air locked

I have a clear fuel filter and sometimes when i drive it it runs out of gas although the tank is full. i can see in the filter there is no gas. sometimes it only takes a flick of the finger to get it flowing again. other times i have to take the line off the tank, turn on the fuel a little and put the hose on as it runs everywhere to get it to fill back up.

    actually i bought it used and the last owner pluged the vent on the tank with JB weld. (not sure why) What a dummy. Guess I got to get the drill out. Thanks alot.

  • Jessie Lamison Jan 21, 2009

    wonder how i can get it out?

  • jvanhyfte Apr 16, 2009

    I'm having the same problem it seems! i thought the accelerator portion of the carb was gummed up. i just changed the fuel filter today. took it out and had to push it around 2 miles back to the garage. sucks! I noticed the fuel filter didn't fill all the way up but it didn't occur to me until i read this. makes sense to me!

    But I've ridden it several days in a row with no problems. Now all of a sudden........

The gas tank breather vent is clogged. Check around your cap and make sure the vent hose under the tank is not pinched. Your getting a vapor lock.

The diaphragm petcock operates by vacuum.
Sometimes, the vacuum line comes unhooked, cracked or broken.

Check the vacuum line.

Also, the diaphragm petcock sometimes dies, and needs replacing.

The reserve DOESN'T operate by vacuum.

Next time it stops, remove your gas cap and see if it starts without waiting 15 minutes.

If it does, your problem is probably the gas tank venting.

Air has to be allowed into the gas tank to replace the fuel leaving it, or it will "vapor lock"

Regulations no longer allow a vented gas cap to vent directly into the atmosphere, so look for a vent line, and make sure it is clear.

Some (like my bike) have a one-way inline valve that allows air into the tank, but doesn't allow fumes to escape.
These valve stick closed sometimes.

I need to find the fuel filter


On a carb model, a lot of times there is an inline filter in the line from the gas tank to the carb, so follow your gas line down.

BUT, a lot of times, there is no inline filter, and the only thing you have is a filter screen attached to the top of the fuel shutoff (petcock) inside the gas tank.
The only way to access is to drain gas tank and remove petcock,

Our scooter sat for 9 months in storage. When we got it out it wouldn't stay running. We ran the old gas out and put new in it and it still wont stay running, but if we take part of the fuel line off it...


its probably your fuel filter... When a motor sits with fuel for a while it will begin to varnish which will clog the fuel filter and sometimes cause the float or jets to stick or get clogged. But if it works with the fuel line detached I can almost promise its a fuel filter issue. If that doesnt clear it up check the petcock valve at the tank.

I am trying to help a friend out and get his 08 nightster 1200 running for him. this bike has been sitting for almost a year. took tank off and cleaned it out and installed new battery for this unit. ...


Make sure the fuel line from the tank to the injector is seated fully. The fittings must be secure for fuel to flow from the pump. Make sure the pump is plugged in to the harness, and the fuse is good. There is a way to check the fuel pressure, but you will need the proper fitting to hook to the tank along with a pressure guage. It is possible that the fuel line from the pump inside the tank is cracked or not hooked to the pump or tank outlet. Hope this helps.

Cycle runs for about a minute and a half then cuts out like its getting no gas. Someone told me to drain gas from petcock hose to see if its the fuel filter. Dont know jack about bikes no clue where...


Is the gas on? The petcock is the little thing that hangs under the tank that turns the gas on and off, level is off, vert is on, and one other level is reserve. I had trouble with my Harley, if it didn't have a full tank, it wouldn't start, But once it was running it would vibrate the gas through the system, but gravity wouldn't do it with little or no fuel. Your tank could be rusting up a little, the filter will tell you, keep one on there so it doesn't get into the carbs. 1971 Sportster,, XLCH. Hope this helps.

No fuel


something to keep in mind. if the fuel filter appears to be empty, this may not always mean that the fuel system is running dry. if you bike runs fine i wouldnt worry about it. usually an air pocket makes its way into the filter and still allows fuel to flow. but if you are running into a fuel starveing problem. cutting out. ect. then after elimintateing the other possibilities you have listed you will want to check the carb venting tubes. if the float chambers are not getting proper venting from a pinched line or something then it will not allow fuel in as adequate as it should, and will cause running problems. or if this is something that occured after a storage period a sticking float valve can alter fuel flow as well. and last, if this tank has venting lines then you willl want to check them as well. venting problems can be tricky to find but they are a common cause of fuel starve problems.
