Question about Motorcycles

1 Answer

The gas needle mostly goes up to a quarter or little less than a half tank when you fill up but not right away, sometimes it's about after you've ride 3-10 miles. The gauge will drop to the low level

I have a wiring schematic of the fuel gauge on a '94 FXDWG. Your gauge may be physically a bit different but it should be wired the same. Harley's fuel gauges are known to be problematic. If you think it may help you on your bike, you'll have to contact me directly as I cannot send a file larger than 150KB here. I'll send you a scanned copy in a JPEG file (Picture file). Remind me of what you need.

Good luck

half chocked is not enough gas usually. Probably a partial clog in the fuel filer. replace it, if one of those bronze cone things on the tank nipple, cut it off and put an inline filter on the fuel, take the carb bowl off, clean the float and needle, then reassemble all. If it still aint right you got to rebuild the carb. I recommend just buying a new carb, a lot less hassel.

Sounds like at 1/4 reading,the actual reading of the fuel should be empty.Your gauge sending unit in the tank is most likely defective.Many are on these.

Fuel sending unit mazda millenia 1998

Well, yes the tank is under pressure at times, but the gauge problem is probably the sending unit.
Every few minutes the computer tries to vent the tank to the vapor canister and the engine which would be affected by the leaking gasket.
You will probably need to replace the sending unit and then you can fix the seal too. Once the seal is disturbed it usually does not fit the hole.

Richard I need some more info from your harley guru

Next time the bike does this, loosen the gas cap and see if this fixes the problem, The tank is vented thru the cap. If this solves the problem, replace the gas cap.

2006 Ford Escape spews gas from fill pipe during very cold weathe

The little air holes above the gas tank hole don't work very well on these. I've noticed it too. Just hold the pump at a little bit of an angle when this happens which will allow more air to escape your tank.

I have a 1991 buick park avenue ultra

Speedometer or fuel gage?

If speedometer which is bouncing around, it is likely a bad ground near where the speed sensor wire harness (which connects the speed sensor to the rest of the "network") exits the transmission housing. It's at the very back of the transmission (you have a 4T60E trans) to the left of where the right side half-shaft leaves the trans housing. Just look for damaged wires. If none, replace the speed sensor for $50-60.

If it is the fuel gage, the sensor is probably not "zeroed"--it's reading wrong, too high, and if it were to start at true "empty", it would read right. Thus, the gage is always reading a little high (maybe a 1/8-1/10th of a tank too high?). This isn't a problem until to stop, start, or turn quickly and cause the fule to slosh around in the tank and starve the in-tank pickup which sends fuel to the engine.

If it is the fuel gage, you should simply put as much fuel in as you can and see if the needle goes far above "F". If it does, note how far it went and then practice filling the tank when the needle is that same distance above "E".

Hope this helps.

Engine runs bad at half tank or less

Ok ready for this one,new gas cap,its true cars with bad gas caps will cause the check engine light go on,or your problem,it has to be pressurized when full and no air in the tank its ok,but as you use gas and have air in the tank with the low fuel the air pressure is leaking pass the cap,thus losing pressure,too bad you had to fix all the other stuff but look at it as an investment,after this works please give me a fix ya thanks
