I haven't done it in a Faiirlane but i'm with Ross. Ive done it in a truck and I would take the motor out if i had to do it again. 

I just pull the trigger too I have not had a problem even when I reuse ptfe fittings without buying new collets.

-12 and -16 will be pricey and around 80aud for a -16 90deg depending on what type of hose you want it too match with
If you know what you want let me know the part numbers Big problem is getting them to the USA now Australia post has stopped all postage going to the USA because of a tariff. So you would have to look into if you can even ship them right now.

Try this mob I think they are in the USA https://autoplumb.com/

Where are you guys getting reasonably priced American made fittings ? Specifically-12 and -16
I been looking at the Australian aeroflow fittings but they are pricey. 

It started out as a gasser project.  But the rules for A/Gas today is only one carb, so that's out.  Maybe Competition Coupe but I haven't verified the carb limits there.

Or some tyoe of AFX nostaglia car. 

I just want to try to see how fast and quick I can go, setting personal bests so the class thing is not important.  I do not expect my eighty year old reflexes will get me more than the first round in any class.
