I'm sure this has been asked and answered before, but I don't know where to find the answer so
her we go. I would like to know if the factory puts a screen on some other type of filter on the end
of the pick up tube in the fuel tank of a 05 CRD. any help would be appreciated as I plan to add a
external lift pump to my CRD's. If there is a filter or screen in the tank I won't add one before the
pump, if not then I will.. Thanks for the help..

Probably but if it's like the ones I've seen on other vehicles it's a pretty coarse screen. I don't think an inline pre-filter is critical but it won't hurt although if you get one I'd get a see thru kind so it's easy to check if it's picking up any crud.

PS - the CRD tank is plastic and unlikely to shed crud like the old steel tanks that can rust inside from moisture in the fuel. Hence anything in the tank that could be picked up had to come in from the outside past the pump filters except of course algae which is a whole other issue.
