secondary fuel filter cap

[06kngrnch84]

I messed up my secondary fuel filter cap, the one under the hood, its now stuck on the housing, any ideas on how to get it off? And does anyone know the part number so i can order a new one? Thanks

what exactually is f'd up. i assume the place to put a socket. u could use a big chanel locks. or can u get a rachet in the square area in the middle of the six point head?

The place for a socket to go is pretty much gone, maybe one side left due to trying channel locks, and I can fit a wrench down inside but it won't grab enough. Was thinkin about cutting that spot on out deeper in that same shape so maybe my ratchet would go on down in there, but i can't remember is there any thing right under the top right there that I might mess up? I have the housing off the truck due to doing some other work but I really don't want to mess up the housing and then have to replace it.

I think there is a stand pipe inside the filter housing.
I'd take a chisel/screw driver and with the housing immobilized, tap and chisel at the filter top at an angle to pop it loose.

i took a chisel and hammer and just eased into it at an angle to get it to start to unscrew. Paitience my friend.

Get a new cap. 3C3Z-9G270-AA

I think it uses 15/16 socket. Don't ever use the 1/2" drive hole to install/remove the cap. You run a risk of cracking the cap. Be sure to lube the O-ring with oil when installing. There is a fuel return tube inside the filter housing that the filter sits on. Carefully remove the filter or you will be replacing that as well. It's another $40 part at the Ford counter!

I think 15/16 is correct. I slip on a filter change a while back and since its plastic, well u know. Been using the 1/2" drive hole for while but finally f'd it all up. Got it off though. Tried chisel and screwdriver, no luck. So since the whole housing was off my truck I took a sawzall and very carefully cut about a 1" slot all the way across the middle, being careful not the let the blade hit the metal housing, broke that center section out, then tap it on the inside with a hammer, worked rather well just have to be careful and precise with the Sawzall.
