Dear Alex98765,

May this find you well. I've read prior posts. When the low fuel warning light comes on, you have left about a gallon, or enough fuel to go about 20 miles. The key word is "about": the distance will vary with the driver, the load, and the terrain. Thus, as soon as you see the low fuel warning light, find a gas station.

Running completely out of gas, such that the engine sputters and dies, is not good for the fuel pump(s). The fuel helps to cool the pump(s), especially the in-tank pump (pre-pump for Bosch; main pump for Rex-Regina engines).

In the last few seconds, before the engine dies (which turns-off the fuel pumps), the pump(s) will move a mix of air and fuel. That will not cool the pump properly.

Hope this helps.

Yours faithfully,

Spook
