Outer Limits 4x4 Board

hi
i've just replaced the fuel filter following the manual and now when i try to bleed the fuel system, nothing but air is coming out of the injector bleed valve. it will start but not running very well at all and i can't seem to get the lift pump to do its job. how long am i supposed to pump the lift pump b4 fuel starts comning through? any ideas?

You should have a bleed screw on the lift pump is its a TD42 engine, RD28T and ZD30's done have it

it takes quite a few pumps to get it to come up

if you don't have the plastic screw on the lift pump do what my mate does and take the fuel line off that leads to the Injector pump and pump it up till it comes out there, connect it back up and start the engine,

been pumping the lift pump for 30mins at a time and not even a hint of fuel coming out either the line to the injector pump or the bleed valve (i dont have them open at the same time)

It is proberly not sealing on the filter O-ring and sucking air instead of pulling fuel through the filter.

ok, so i've tried everything but i think i've realised what it is: the plastic water sensor fitting that screws onto the bottom of the filter has a small hole in the side. when i unscrewed the water sensor, there was zero diesel in the filter. when i put my finger over the small hole on the side of the sensor and pump the lift pump it tries to draw air in. but, i never removed any sort of plug from that. is there supposed to be a plug of some sort in it?

try to fill new filter with fuel.

I open the bleed valve and use a compressor to blow air into the fuel tank (using a rag around the gun so tank pressurises) and it seems to work fine.
