how many fuel filters are on a PSD?

[Jesse.James]

I changed my fuel filter up on top of the motor right after i got my truck but i was wondering if there was another filter on the frame somewhere?

Not from the factory but if your smart you will install one like I did and do the fuel tank and prepump mods while your at it. Total cost is less than $35. It might save you thousands of dollars if you get a bad load of fuel. Take a look at my fuel system pictures in my signature link and at how my filter looked after a bad load of fuel that ruined my injectors. Also a factory filter should be changed around every 8-10K miles unless you have a prefilter setup installed. Factory filters are around $20-$30 each time and my prefilter cartridge is $5 at tractor supply.

I did the same thing. The Ford Parts Manager at the dealership I use gave me just one. The part number I have is FD4596.
