How do you fix a bleed plug in a fuel pump?
Most all equipment has a hand priming pump lever to pump fuel through the system and replace trapped air. (Check operator’s manual.) Pump several times until full flow, without air bubbles, escapes from the bleed plug holes. 8. You may need to bleed filters, fuel pump and lines to the injectors.
What to do when your fuel line is bleeding air?
Open the bleed plug on the filter closest to the fuel tank. 6. Open fuel supply valve so that the fuel is available to the filter and pump. 7. Most all equipment has a hand priming pump lever to pump fuel through the system and replace trapped air. (Check operator’s manual.) Pump several times until full
When to close bleed plugs on diesel engine?
Close bleed plugs after all air is removed from the fuel tank, filters, settlement bulb, and fuel pump (only one at a time working through all bleed screws beginning closest to tank and ending at nozzles if necessary). 10. Try the engine; if it doesn’t start or runs poorly, you may have to bleed the injection
What causes a diesel engine to bleed air?
When you change a diesel fuel filter, run out of fuel or disturb the fuel system, air is trapped. When you try to start the engine this air acts as a lock, preventing the normal supply of fuel into the cylinder. Here are the steps to take in bleeding air from a diesel fuel system: 1. Turn off fuel valve.

What is a bleeder valve on a fuel line?
Locate the Schraeder valve. This valve looks like a valve stem that you would normally find on a tire. This valve is a bleeder valve that will release pressure and purge air from the system if you loosen or remove it.

How do you install an injector fuel line?
Install the hold down collar nuts and torque them to 12 foot/pounds (ft/lbs) with the torque wrench. Install the injector fuel line and tighten it down loosely. Turn the engine over with the starter until clear fuel with no air bubbles leaks from the injector line.
