Best fuel filter

[01Crewcab7.3]

I will be changing my fuel filter tomorrow to see if it will help increase my fuel mileage. My question is should i go with the Motorcraft or get the Wix? Or is there a better one than either of those? Thanks

Not sure if changing the filter will affect fuel economy too much, but I believe Motorcraft or Racor are the best fuel filters for the 7.3.

Well if the filter is older (only owned the truck a few weeks so i do not know the condition of the current filter) they can hurt fuel economy (not drastically) but even so if the filter is old i need/want to replace it none the less. Thanks for the reply, i will go pick up a motorcraft tomorrow morning then.

i had issues with the fuel filter cap leaking (yes, it was a brand new one along with a new motorcraft filter) so i tried a wix one with the built in top and it seals up fine. i change it every oil change (cheap insurance for my mind that needs peace) so it never gets real dirty.

EDIT: yes i know the o ring is made to go only one way. my old cap was leaking so i figured id do a new filter with new cap, still leaked. switched to the wix, no issues now

Never had an issue with the Motorcraft filter and separate fuel filter lid, just make sure to follow the directions and get that o-ring on top right! IIRC the bevel goes up.

ya, we have done plenty of fuel filter changes where i work and never had an issue but for some reason, mine was leaking and then the new filter and cap and still leaked. my pops called me a dumbass and said "you prob put the o ring on upside down".... nope. oh well, wix fixed it.

I've been using the WIX#33818. It has the integrated lid. They've been working fine for me.

Alright then maybe I will get the wix instead. Thanks a lot for the info.

i actually just replaced mine today, along with oil n filter change. motorcraft didn't come with the cap so i got a purolator. it came with cap and o rings. it was very easy to do. took me bout 10 min... no leaks.
