bleeding the fuel line

[timber]

Hello to all,
I think I should bleed the air out of our zetor 7045 's fuel line. I can see that the glass bulb under the primer lever has only 1/4 amont of fuel in it when Zetor is running. the screen inside of bulb is barely submerged in fuel, at most 1/16 and after changing the two fuel filters yesterday I ran the zetor for 1 hr and the zetor shutdown because of lack of fuel. when not running {at rest} the glass bulb fills with fuel. this must be what fuel runs back from fuel pump. Does anyone know how to bleed the fuel line???????

it's of no use bleeding the fuel line. either blow it out with an air compressor (dont forget to take the cap off the fuel tank or the compressed air you blow into the tank will press out the fuel, making one big mess) or you replace the whole fuel line.
