Hi there..I have a TPI swap project going on so I bought a complete TPI kit.
The fuel lines that is connected to the fuel rails is very rusty and should be taken off or replaced.

Is it possible to replace theese metal lines?...I attached 3 pictures so you can see what fuel line I mean. The one with the red ring round.

 

Just looks like normal surface rust. You could just clean it up and paint it.

 

Yes I am going to do that today. I'm taking it to my work and there I can glas-blast them so they would be free of rust.
After that I can spray them with a good primer.

 

dont blast them

just clean it up a bit and spray with some etch primer and then paint

 

I am at work now and have already blasted them...actually, they look perfect now but I am going to get some paint on them also.
we have a very good glas-blasting machine at where I work so I often use this one to clean up dirt and remove old paint/rust.

Then I put the items to a big washing machine and wash them at 80 degrees Celsius for about 30minutes. Then they are nice and clean

I think I am going to polish my TPI setup more after I have got it up running. I have just polished some few parts and I think I will take the rest later.

 

Are you sure you didn't get any media inside them?

 

I did use ALOT of compressed air after I washed them so they should be completely fine..
