My 300 TDI has the fuel filter attached to the chassis just in front of the tank, then the fuel goes to the lift pump.

Everything I read says it should go to the pump, then the filter, then the engine, but i don't know how important that is.

Is this something I should worry about or not?

if its a disco its a sedimenter secured to chassis,often best bypassed

had another look - the engine and some systems have come from a disco 1 and are now sitting in my 1983 One Ten, so it could have been something installed straight from the disco.

But it is a filter, I'm pretty sure.

I might buy a sedementer as it's VERY dusty out here, and it gets everywhere.

BUT should I move the filter so it sits AFTER the fuel lift pump or is it simply not an issue?

Yup your pic is a filter-strange location.I would have the filter after lift pump and before injection pump,to protect injection pump-that way only filtered fuel goes to Injection pump via fuel hose,if lift pump should fail or break up filter will catch bits

There is no such thing as to clean fuel, for a diesel... Is there not one on your firewall?
