Replacing fuel filter in 6.6l v8 diesel truck

The fuel pump may be starting to go bad, when you get below half a tank, the pump does not submerge in fuel as much to keep it cool and it will seize up and stall the motor. You will need to replace the pump and check inside the bottom of the tank for small metal bits that almost look like shiny sand.

for Manual Valve replace. Thanks

Have you changed the fuel filters in it lately?

Possible water etc in the filters..

black smoke = excessive fuel = bad injector tips , low injector pressure , turbo not working properly
take the car to an accredited diesel specialist professional for a pump pressure and injector pressure test, injector calibration and tip replacement

try to replace the fuel pump. possibly cause might be you replaced your filter a little to late, that some dirt already entered your pump. also, try to clean the fuel lines itself.

dear . you have water mix with diesel . dont start again . replace diesel filter connect fuel from out side , if you find injector cleaner try use it , after replace fuel filter try to put 50mm engine oil in fuel line . for lubricate and remove rusty.

Here you go if it is a diesel:
A. FUEL FILTER REPLACEMENT:
The fuel filter is located inside of the fuel filter housing
1. Unscrew and remove fuel filter cap at top of fuel filter housing. To unscrew, attach tool to 6-sided hex center of cap. Do not loosen cap at outer edge. The fuel filter cap is designed to remove filter while pulling up on cap.
2. Remove O-ring from cap and discard.
3. The filter is retained to cap with little fingers. Carefully pry a couple of them off from old filter.
B. FUEL FILTER REPLACEMENT:
1. Thoroughly clean inside of filter housing, cap, etc. with clean diesel fuel
2. Fill filter housing (canister) with clean diesel fuel. NOTE: If you do not do this, you will have to manually bleed air out of system later. No fun.
3. Snap new fuel filter to bottom of cap.
4. Install new O-ring
5. Apply lihgt film of clean diesel oil to cap O-ring
6. Load filter/cap into housing.
7. Tighten cap to 25 ft. lbs. torque. Do NOT over-tighten.

check your filters and fuel filter.. if they need to be replaced then do so.. then check your fuel pump.. a mechanic can tell you if you need to replace that or not... and check your starter, alternator, and battery cables

it should be located on the fuel line around the middle of the car if not its about 2 1/4 inches by 4 1/4inches

Undo the fuel inlet Banjo bolt and carefully fish with a piece of wire bent at the end (as pictured) and fish out the filter (under the spring) wash and replace. Can be very fiddly, so patience is a must.

When you get some fuel you can unscrew the fuel filter and fill it with diesel. Then put the filter back on without spilling the fuel.

There should be enough diesel to prime the motor and get rid of the airlock. Also with diesels make sure you are using the correct tank if you have a tank switch.
