They say no good deed goes unpunished. I thought it would be a good idea to change out my inline fuel filter and cartridge fuel filter. It's my first time so I did read up on it. After changing the fuel filter I loosened the bleeder screw at the cartridge filter turned the key on until I seen fuel coming out. Now my engine just turns over and maybe a couple puffs of black smoke. After reading other post I decided to crack open the fuel lines at the top of the injectors. Seems like I only get a dribble of fuel out of one line. Machine was running fine before I serviced it. Any thoughts?
