Penetrating oil (fuel filter)
Discussion
The nut on top of Toyota Avensis fuel filter (petrol) is difficult to remove. It looks like a banjo joint. On the line that goes to the engine. The bottom one maybe also seized, but never tried that. What is the best penetrating oil to use on this?
thanks
thanks

Penetrating oil won't work, as if there was any way the oil could get down to the threads, past the sealing ring, petrol would be pissing out all over the place, use a bigger leverage to undo the union.
I feel like damage would occur if I put too much leverage on it. The banjo joint has a copper washer. Edited by RayTay on Sunday 6th January 23:54
Why do people still imagine that fuel is somehow 'sucked' from the top of the tank? It is taken from the lowest part of the tank, so if it's going to 'suck crud', it will suck crud all the time!
OP - if their is any seizure, it is likely to be just under the head of the bolt, not the thread for reasons previously mentioned. An application of Plus Gas may just about do the job.

Conflicting opinions.
1. Penetrating oil will do not good.
2. Penetrating oil will work.
There is no conflict, penetrating oil needs to get in there to work, it cannot do anything just sat on a bolt head.1. Penetrating oil will do not good.
2. Penetrating oil will work.
If you are trying to remove a banjo bolt it has seals that stop the fluid/fuel getting out which will stop the penetrating oil from getting in.
Simples!

Freezing is now in the ring.
Penetrating oil rarely does much good in reducing breakaway torque for normal bolts IME, and will certainly have no effect when there is a sealing washer under the bolt head.1. Penetrating oil will do not good.

The threads should not be corroded on a fuel system banjo bolt unless significant amounts of water are in the fuel system, so it sounds like more torque is required.

To change the fuel filter. The fuel tank went down too low and I suspect crud has been sucked up and partially blocked the filter.
So why are you thinking you need to change the filter, are you actually having a problem?Not familiar with the car so pardon the ignorance but I know of no car where banjos need undoing to change a filter, do you actually need to remove the banjo connection to change it?
The bolt threads into the filter itself, yes?
I'd just get new ones and undo it. If it shears, it shears. New bolt goes into new filter.

The issue is when the fuel gets really low and you refill the tank, the fresh fuel seems to swirl up any crud that's there and hold it in suspension long enough to get pulled through and bung something up. Had it happen a couple of times.E-bmw said:

Fuel starvation at high revs. Just after running way too low on fuel. First port of call is the filter. Not familiar with the car so pardon the ignorance but I know of no car where banjos need undoing to change a filter, do you actually need to remove the banjo connection to change it?
Look at the video I linked to.
