1999-2003 Ford F250 F350 F450 F550 7.3L Powerstroke Fuel Filter Housing Assembly F81Z-9155-AC FG-1057

Idk what this does but apparently it works

Install was fairly easy ,just make sure you have good lighting and a long thin screw driver to lift the passenger side lines into place ,other than that its pretty simple ,i filled the filter bowl half full with seafoam additive ,its great for gas or diesel engines,before putting the cap back on ,make sure you add just a lil more oil to the sealing surface ,plus i ordered a filter wrench for next time ,be careful not to over tighten ,as its easy to do.my engine has over 300k ,and I was recommend Archoil products for oil and fuel,,my engine oil pressure went up by over 5 psi and the engine is quieter than before,It did not total fix my hard start issue ,but it is now manageable.

Great fit, replaces stock fuel filter housing.
