i have a 2008 F450 6.4 diesel. i changed the fuel filters today. The low pressure frame mounted pump runs, but no fuel. Ford dealer says it also has a pump in the tank. i went thru all the procedures to bleed the line, no fuel. does anyone know if there is a pump in the tank on the diesel, or is that for gas only? how do i check both pumps, without buying new ones?
Thanks for any info.

 

UPDATE, Replaced the lift pump (on the inside frame rail).
turned switch on 1 time and filled bowl on filter on top of engine.
then cranked right up.

 

Nice glad to hear you fixed it bet you where relieved to see that.
