bleeding diesel lines?

[04mach1]

( in my 93 IDI diesel )

hey guys my fuel lines looked pretty gross so i ripped them all out and replaced them all.

now i have heard that you have to bleed the system so that NO air is in it. unlike a car where you can just flick the pump on and go.

can someone explain IN DETAIL how i would go about bleeding my fuel system????

again i replaced ALL THE LINES front to back, every inch.

thanks

I don't know about these motors but IIRC my grandpa just cracked the fuel lines going to the injectors on the engine and cranked it over til all the air was bled out. That was on his 89 idi ford. Hopefuly someone who knows will post on it

That is what I was thinking too Stroked 95 But I was not sure. I know that on the 6.2 and 6.5 Gm Diesels when I was in the Corps that is how we bleed the fuel system. Just crack open all the fuel lines and crank the engine and have some one watch the fuel lines going to the injectors. When there is fuel coming out of all the lines. You stop cranking and you tighten the fuel lines down.

im not sure if i explained myself right..

so here we go.

i replaced the lines from the tank to the bottom of the motor in the front ( where it joins to go up to the filter on top the motor )
and where it comes out of the motor on the top on the drivers side back to the tanks.

so since my fuel filter forward HAS fuel still ( to the injectors ) can i crack the line before the fuel filter and crank the motor till fuel comes out there?

also do i have to do it once for the front tank and then again for the rear tank?
thanks guys!

If you have not messed with the injector lines, just the fuel feed lines, you should be able to crank the engine while someone presses in the schrader valve on the fuel filter housing until the air is out. Start with the rear tank until it is runnig good, then switch to the front. You should not have to bleed it again, but if so, do it the same way. All you need to do is bleed the air from the filter.
