Dometic fridge parts. RM4211

I have the fridge above and the last 4 years have had to have it serviced with the same fault.
There's a pipe that goes from the back of the fridge where the burner jet valve is up and over the top. The pipe is rusting inside and so flakes of rust fall and obstruct the valve so the fridge doesn't work properly.
I have tried to work out from the diagrams on leisureshop direct which part this is to see if it's available as an aftermarket spare but they are not clear to me so I will call them next week. I suspect from what I can see that it's not.
However rather than replace (if there is a spare) is anyone aware of a way that I can restore the existing without blocking it, silicone spray works temporarily but I don't want to be taking the fridge out every 6 to 12 months when it only sees about 10 days a year of off grid living.
Alternatively does anyone know if this is just a standard part that can be replaced with an alternative, seems to me that we must have had technological advances that mean there's maybe someone producing a part like this that fails with time, but then it would need to be the same guage pipe to regulate the gas flow

Thanks

I think it is an 8mm pipe we had one rust through and start leaking in a caravan when we were away. Went into a plumbing shop (many years ago) they made me a new one from copper using the exsisting end fittings. From memory they are flanged ends on the pipe so a garage with brake pipe flange tools may be able to do it.

Thanks, I'll look into that.
