353 detroit diesel fuel filter question

[roundbarn]

Im looking for some advice on which one of these pics is the fuel filter. The engine doesnt seem to be putting out as much power as it did last week and I was thinking it might be time to replace the fuel filter....just didnt want to take apart the wrong one.

It look like ones primary and other is a secondary fuel filter

There both fuel filters, lower one should be primary. Last photo is the blower

[lewis]

also make sure the flap in blower intake isnt closed because I dont see the catch in the photo

Make sure your fuel lines are clear mine had obstuction on the intake line which runs from tank to filter

Hi mate
there are 2 fuel lines at the rear inside of the tank back one is to the filters from memory both have taps on them
may be an easy fix i would try this first i have had trouble there before
Good luck Summercutter

If less power & more smoke you can check the air filter also. I have air flow indicator's on mine. I think they have 4 levels so I know before there totally plugged.
