Actually that light isnt a RESERVE LIGHT, its a light to let you know your low on fuel. There are no such things as reserve fuel on these cars. The light comes on at different times in some instances so I wouldnt rely on that light to let me know to put fel in it since its really hard on the fuel pump to keep it that low all the time. Not sure why anyone would waste time installing a used part, I like to spend my free time not working on cars

But no on the reserves. Everyone sort of figures it was a reserve since they keep driving but the light is just a reminder since we are not smart enough to look at the needle to see it cant go no further so the car manufactures installed a little light to see if it gets driver's attention since that pointed needle doesnt

It is not a Harley. You have one tank. My question is " A used fuel pump"?

Answer this: If your tank reads one quarter under (you mean over) why does it still have six gallons in it when the low fuel light comes on??

Changing a fuel pump and float is a pain in the butt. You get what you get when you put used parts in there.

Reserve light is generated by a contact point instead of slide resistor. I Ibelieve it works correctly. So fill the tank whenever it start blinking.

Not to mention that now - when it measures one-half - is it half full or half empty?

daft.

The fuel light is not correct. You can replace the pump again or track how many miles you drive before fill up.

I replaced my fuel pump with a used one and unfortunately the used one had a bad sending unit. So now my tank reads 1 quarter under.

When the reserve light turns on and I fill it all the way I can put in 8 gallons. My car holds 14 gallons.

My question is, when the light goes on, is it using reserved fuel or the remaining 6 gallons is incorrectly reading?
