Help Needed (Fuel Filter)

2006 LBZ

I installed the fuel filter WITHOUT the big oil ring that goes to the housing.

I over tightened it, probably..

leaks fuel between the top of fuel filter and housing, where the O ring is missing.


Truck wont run or start - OBVIOUSLY


My problem is I can't get the fuel filter back off. I spun it 15 times counter clockwise, it just spins and spins,,, doesn't come off.

It is on there so tight you need a wrench to spin it wither direction, but wont get tighter or looser ... no matter what



how in the world can i get the fuel filter off NOW ??

1/2 turn, after contact.....by hand.

Without the O-ring, and spinning past the 1/2T point, it's probably off the end of the threads on the filter head.
Not sure how you could apply downward pressure to try and start the threads again.

Good news is, a complete filter head with a new filter isn't expensive. Then it's just two bolts to swap.
But that won't help on a Sunday, sry.

2006 LBZ's do this all the time and there is no "FIX", no matter what Hooky just told you.

This is why resale values on them are so low.

I really feel for you, in your bad situation. So much so that I will come over and give you $10k for your truck, which is far above Blue-Book value. (Dont bother to check...)

Use the $10k as a down payment on a 2020.... it's a Win-Win situation.

PM me your bank info, and I'll wire you the funds.

I forgot to put in on, I'm not very good mechanically , still learning .. sorry .


So far, the only way to get it off, is to swap the entire "head assembly" or whatever that's called, the part the filter screws into ?

What if I used a screw driver and tried to pry the filter off, destroying it in the process.. . then just buy a new filter ? or is that a bad idea ?

The threads go clear to the top. The only thing that can be going on, is the crimp holding the filter "can" to the "mounting plate" has failed and when you loosen the can part, its spinning on the plate due to the failed crimp.

I've never seen it happen, but it's all I got.

I would definitely try that first.

you are already screwed so even if you need to tear it off in pieces... have at it...

I would try using something such as putty knife or metal scrapper to wedge between the filter and the housing to apply downward pressure on the filter while trying to remove it. Maybe it will catch and come off. Good luck.

A putty knife could fit, but might not have the leverage and I doubt a screwdriver could wedge in without damaging the soft metal filter head.

The canister head may have separated (what brand is it?), but the soft plastic threads could've flattened out and no amount of downward pressure will have 'em mesh together again.

I thought about if you removed it and used a filter cutter to open it up and cut thru the plastic filter head edge, but the two metal tubes will be in the way. In the way also in trying to pry downward.

Doesn't hurt to try though.
I would just replace the whole assembly, two bolts and two fuel line clamps...much easier than changing the filter alone, as the new assembly just drops in and bolts up.
