Hard fuel line
 

I have a new electric fuel pump ordered, and my existing line will need to be replaced. In the past I have used steel line with double flared ends.
Bending it up has been a challenge because I am fussy. I like nice even straight runs. I get a little better at it each time though.
The steel 3/8" diameter stuff is good and rigid. which is a virtue in many ways. But it's stiffness makes it hard to bend.
I am thinking about whether to use that aluminum line because it's not as hard to bend. Or maybe some of that easy bend stuff.
Any ideas?

The fuel lines on my 50 year old Hatteras are all copper.

vibration will kill aluminum lines in time, steel will last nearly forever. make sure you have a good quality bender and flare tool. cheap ones will make life difficult.

Ayuh,.... Same question here,...... What are you usin' for a tubin' bender,..??

I've got a couple of different brake tubin' benders, that if 1 won't make the bend I want, the other will,....

Aeroquip pushlock for the win. :):evilb:

Go to the parts store and get coated steel line. Won't rust and bends great

Are you using stainless steel?
That is what I used between the fuel rails and the regulator and the other end of the fuel rail and the distribution tee.
It was a ***** to form.
