Diesel Fuel Injection System Help Desk

Hi DD,

My choking problem keeps on going back everytime my fuel level reaches slightly below 1/2. Ano kaya ang problema? I already replaced several fuel filters, scv. Napansin ko lang lately pag full tank ulit ako biglang nawawala ang problema. I think there is air going in the system. Whats the first part I should test?

Thanks sir!

Baka may butas sa bandang gitna yung steel suction pipe sa loob ng fuel tank.

You can do this. Replace the black hose between your fuel filter and supply pump with a transparent hose. Check for presence of air bubbles when your fuel tank is full and when the engine starts choking (fuel level below 1/2). If bubbles start appearing only when your level is below 1/2, you've solved it.

Don't forget to put back the original black rubber hose.
