Hi All,
So I damaged my fuel line in my 96 Lexus ES300 right below the fuel filter, I simply twisted it and tore it off thinking that I was unscrewing my rusty filter. I should have held the nut at the fuel line with another wrench... Never mind... So new fuel line is about $70 and it goes to the firewall and probably directly to the tank. However I found out that flaring tool makes pretty good fittings that can hold the fuel pressure. I measured my fuel line's diameter and it is 9 mm since Japanese cars go metric. I went to Sears and found Craftsman flare tool set with only 4 adaptors (not metric). Next I looked around online for high-end sets. There are 2 metric sets and 3 SAE ones. Both metric sets have adaptors with 8mm and 10mm but no 9mm (as my line is). SAE sets have 3/8 adaptor that would be closer because it is approximately 9.5mm.

1) I would apprecite if somebody gave me a clue how accurate they have to be to hold a tube because I have never used this kind of tool. And should I buy metric or SAE set?

2) Next question would be which line do I flare - the one in the engine compartment or the one with the connector that firstly I have to purchase somewhere or cut off at a junk yard.

3) what kind of flare should I apply to fuel/brake line - single, bubble or double
4) what if I don't find it at junk yard, can I use old connector? There is still old tube remaing in it, can I remove it somehow?

5) where do I buy fittings? And will I find one for 9mm tubes? Or will 3/8 fitting fit to my line?

I know that I have too many questions but maybe I will be lucky to have some answers... And the topic may be helpful for other people.
