I took my car to the mechanic today to change the fuel filter. After 2 hours of work he says he still couldnt unscrew the lower nut (fuel intake?). Packed everything back the way it is. Any advice?

The nut is all battered from him trying to take it off but it still wouldn't budge.

(It's a 7AFE btw)

was it really that rusted together? best you could do from there is get a nice vice grip and get it on the fuel filter nut and get a wrench for the other one and goto town on it.

Put some pb blaster on there too or something like that... it helps alot.

if your mechanic dont have a proper flare nut wrench to get that lower nut loose without destroying it, its time to find a new mechanic.

even with the flare wrench it can still be damned near impossible to get that apart. i had all the right tools and i could not do mine on the car correctly at all. if the nut seizes to the line and won't spin on the line it can get nasty in a hurry.

atleast he was honest about it.

what he said. speaking as a technician myself, if the guy can't handle a fuel filter, i wouldn't take it back to him.

first you need a flare nut wrench, and pb blaster. get the two wrenches, shape em up like a scissor and squeeze em together. mine was stuck like hell too. of course if it is too damaged you may have to use a vice grip for the lower nut. you might need to also reflare that line if needed.

Actually that's the first mechanic who managed to find the bloody fuel filter without me pointing it out for him after 5 minutes of searching.

Nevertheless, going to see a different one tomorrow, hope he can get it off.

Which reminds me, what's the interval for the filter change? 50 thousand kms? More? Less?

x2 to that and presure's post. I had a hell of a time with mine and wound up taking it to a shop to get help with that lower nut once my knuckles were bloodied enough to give up.

Finally found a mechanic who can tell his elbow from his arse.

He managed to take it off in half an hour with A LOT of swearing (especially swearing the previous idiots).

So yes, it was a hell's task to take it off but just as hard to find somebody who can actually do it.

Thanks for the hints and tips, folks.
