[s-cars] Fuel Odour from Under Car

[Sean Douglas]

Mark:

How did you do this? Did you find the proper fittings and flare the
copper pipe to match? I'd be interested in your details.

Looking through ETKA, it doesn't appear that the threaded male fitting
that connects the hard pipe to a flex line is available - unless I pull
one off a donor car. But it does look like the M-M coupler is available.
Also, are bulk metal fuel lines available, if so, then I'd have to
figure out what type of flare the OEM pipes use and where to buy this
tool.

I'm trying to figure out a DIY way of fixing this, just priced out the
new set of hardlines, $300, ouch!

Thanks,

Sean
