how would i clean diesel fuel lines?

whats the best way of cleaning some fuel lines for a ford diesel?

If youre talking about cleaning gum and varnish buildup from the lines, most of the good quality fuel treatments will do it over a period of time. There are alot of different brands, i use lucas. I imagine they have the blended bio-diesel in ca. , it will clean the tank and lines, but be prepared to change the filter regularly , till it gets most of it out, it has a much stronger solvent action than pure diesel. If this the same truck from your other post, there should be a fitting on top of the filter housing to bleed the air out. It looks like a valve stem, with the same type of cap on it. I think the turbo uses the same plumbing here as the normally aspirated engine. The valve on the bottom you spoke of is for draining off water.

ok today i played with the engine all day

i found its not my fuel lines anyways

the turbo is spitting oil in the intake for the motor at higher rpms and making it surge and then die

so i might need a turbo rebuild im still searching for the answer

is it normal for the turbo to be sucking oil from where i believe the hose comes from where the pcv valve is supposed to be

i took off the hose leading to the banks turbo manifold and theres alot of oil inside the oil and the intake manifold has oil inside there

i think that stuff is cloggin my engine at higher rpms!
