Hi I'm trying to remove my B-reg sierra XR4i fuel filter and when trying to undo the inlet onion the nut is stuck solid!
I've strayed WD all over it left it over night and tried again today and the filter itself is starting to buckle rather than loosen!
I'm using pair of grips holding the filter and spanner on onion nut!
Any ideas guys?

 

i would cut the filter apart until i could get to the thread then hacksaw/file away .the metal until it released

 

Cheers mate

 

Is there not a place for a spanner on the filter next to the nut. If it fails try mat lewis for new nuts and bolts and just cut it off.

 

Yeah there is but it's starting to buckle on that bit!
I think cutting it off might be easier cheers

 

Get some heat on it


lol.

 

Lol did think of that but had visions of a smouldering car

 

I bent the pipe right round but got the filter off... need a new pipe now.

I guess you could go though it with a screw driver to hold it but fuel will pour out.

 

Id warm the filter housing with a heat gun as the alli will expand faster than the steel fitting
Then try again

 

Dont think a screwdriver will hold it if a pair of grips wont?.?
Bit unsure about using a heat gun!!!
Might try pouring a kettle over the housing see if that works!!

 

I mean pierce through so it holds it.

Why not just cut the pipe and start again with a new bolt?
