Bent mine by hand and when I needed a descent bend, I put a length of extension cord inside w/lube, bent to desired shape and pulled out the cord. Chase each piece/section w/a good cleaner and compressed air and done.

I did mine by hand and used a fat propane bottle to make a loop of 3-4 coils at the ends for future repairs.
v-groove pully works good also
i used a a couple diff size pvc pipe pieces to make smaller bend in the 1/2 alum line.
I ran alum from pump up towards the reg and then went back to braided line,so everything you see is braided and the supply and return line down the frame is alum line,i also used the foam insulation for the home a/c lines on the hard lines down the frame then straped them together and to the frame. very cheap and may help keep the fuel cool and alum for chaffing on the frame.
heres what the vent line looks like around the fatt propane bottle

That cord deal sounds like a great idea.
I found years ago that the fittings is where the most money is spent. Braided line is so much easier and the line itself is not that expensive.
That is just a decision you have to make for yourself. But, you cannot run alluminum line outside the confines of the frame or inside the frame in the driveline area. I think on UNIBODY cars the rocker is considered part of your frame as long as it is complete. You may want to ask a NHRA tech guy to be sure.

Quote:I have used that too. Just don't get crazy trying to bend too sharp.
I picked up something from a hardware store years ago that works. Its a set of external coils in different sizes (1/2, 3/8) that you slide over the fuel line to keep the line from crimping when bending by hand.

A little side-bar Q ... how does this alky blended fuel affect the alum line?
Quote:
or the inside of the alum fuel cell
its soft alum tubing,you do have to work it kinda slow but can be done by hand..i did have a buddy help hold the can.
I had the line all the way to the reg,flared both ends and used the flare nuts,then went back and cut it back down under the firewall and used a hardline comp fitting to braid line.
I was gonna poke the vent line down thru the bed to vent under it...but with short pipes I thought I best not and made that coil set up with a flare nut.
gonna get one of those mini cone breathers for it on the open end
ther is another coil on the return line under the truck below where the line comes up thru the bed.

Scratch'n, that's fine for the street but it won't pass tech. There can't be any fuel components mounted on the firewall in line with the flywheel/converter area - I think it has to be 6" in front (or behind). They don't want brake lines run across the firewall (over top the bellhousing area), either. Not trying to nit-pick - just a heads up to anyone who is going to try to pass tech.

What about fuel line? Is there a requirement for what line to run and where it's to be put as it passes the flywheel area?

You can run the fuel line across that area IF you
put the line in a steel tube... I forget what thickness
the steel has to be.... either 1/8 wall or 1/4"
BUT they wont pass with the regulator on the firewall...
must be 6" forward of it
