Fuel capacity

Post by Fuzzyswing » Tue May 22, 2018 9:47 pm



My 1988 gl1500 only holds about
4.3 us gallons of fuel. Did Honda have a smaller size tank in 1988?

No. How did you come to that conclusion ?
Even before the reserve light comes on, you should be hitting near 5 gallons.
6.3 gallons including reserve.

If your fuel gauge is not adjusted you will get a false reading (lower than actual level), but the fuel low light will come on at 1 gallon (3.8 liters) each time.

You could bend the float arm down to read the level correctly.

Remove the seat,
Remove the fuel pump,
Locate the float arm with your left hand while your body facing backwards,
Bend the float arm with your thumb while holding the arm with other fingers,
Check the gauge and repeat it until the gauge reads correctly,

When calibrating mine, I emptied the tank completely and added 4lt (1 galon) of fuel (fuel light should come on in 3 min when the fuel pump is reinstalled), and bent the float arm so that the fuel gauge will read just below E line.

After that, I checked the gauge while refueling and it read correctly as I added 5-10-15-20 liters of fuel (24 liters=6.3 galon total).

After this calibration the fuel gauge will show Full and stay there for the first 100km (60mil), and then will start showing correctly for the rest of the scale, which is more important for us.

My low fuel lite never comes on
Except before I start the bike.
When the gauge shows in the reserve for a while I stop to fill up and look in the tank with a flash light . I see just a small puddle in the bottom of the tank. Is there more fuel that I can't see, for the reserve?
Thank you for the reply!

From the fuel neck it is not easy to see the bottom of the tank, the rear part where the fuel pump is deeper and wider, so you probably are not using the full fuel capacity, and refueling before the fuel low light comes on.

It is the bulb test done by LCD unit when you turn the ignition key on. Normally, the low level light is controlled by a thermistor on the fuel pump unit, and it takes 3 minutes for the light to come on as the fuel level drops below the thermistor level in the tank.

here is what I do when I ride my wing, I fill the tank when the gauge shows " E " I know there are about two gallons left in the tank but I do it anyway on the majority of my rides cause I'm usually ready for a break by then. for more serious road work I take the Mighty ST 1300 and do 275 mile fuel stops without using the fuel cell

The sending unit for the reserve light could be bad, The light will come on when you first turn on the key but if the sending unit is bad the reserve light will not come on when the fuel gets low. You should get about 40 MPG with your wing. So I would ride until you get about 180 - 200 miles on the trip meter and then stop and fill it up and seer how much fuel it takes. The fuel gauge can be off and reading low before it actually is low.

Another reason for low MPG's can be in your right wrist. The more you crank the throttle the less your MPG will be. If you keep the RPM's under 3,000 you should get close to 40 MPG. If you still get bad mileage check your air filter and spark plugs and maybe synchronize your carbs

air filter and spark plugs and synchronize your carbs, all been done, runs excellent, maybe right wrist issue, new to this bike, come off a VTX 1300

I think your best bet is going to be to carry a 1 gallon gas can with you, and observe the gauge and the fuel light as the fuel runs down. Then you'll at least know how the gauge behaves from full to empty, whether the reserve light is functioning, and just how many gallons it actually holds.......without getting stranded. Actually, if your reserve light comes on, I would bet it is pretty accurate. Fill up soon after, and you'll know the tank capacity to that point. Should be right at 5 gallons. I don't think I'd intentionally run it dry. I don't believe that's good for the pump, as fuel is what lubricates and cools it.

I have a somewhat aggressive right wrist and probably average 36 to 40 mpg depending on the fuel I buy and how many slow pokes I have to pass that day. I usually get about 170 miles before my fuel light comes on and takes about 5gal to fill up. I have pushed to 200 miles a time or two and took almost 6 gallons to fill back up.
