Aluminum Hard Lines for Fuel Delivery

OK or just ok?
I am a little worried about the softness but I like that I can better emulate the stock installation with hard pipe.

For that sort of thing I use "Bundy Tube" it's a Copper coated Steel line but you need a good quality bender and flaring tool to get good results.
(This is what I did my fuel system water and fuel lines with)

Thanks. I'll check into it. If the required tools cost a bunch I will stick with the AL.
I think my bender was around the $100 aud mark and the flare tool less.
I run 3 x 10mm high pressure softlines all the way from the tank (400psi line pressure) then use the hardlines in the engine bay as they're more compact.
Not a big fan of hardlines that aren't shielded in some way in case of an accident.

Wow, I was considering just the opposite. Run hardlines from the tank to the firewall and then run softlines.
I figure in a big accident the steel reinforced softlines have a much better chance of not rupturing 
(I've had one such accident and the end results weren't pretty)
(I've had one such accident and the end results weren't pretty)check into "pushlock" or sometimes called "twistlock" fuel line. thats wat im using- 1/2in feed, 3/8 return. its an nhra legal rubber high pressure fuel line- for fuel injection. very simple, just buy and cut to length. fittings have barbs on them and just push into ends of hose, a sleeve then goes over it. i bought it from jegs.
Question answered. Agree that a softline is more durable. I just don't see the point of braided lines under the car. Maybe this is what supra_ed is addressing
exactly. i didnt want to screw with the expensive braided shit- although it looks better. its also a lot more difficult to put the fittings on. pushlock is the way to go if ur using soft lines. looks just like regular fuel injection line but 100x more durable. nhra legal fuel injection line. strongly recommend itBlackfin said:
Why three 10mm lines. A single 1/2 inch (12mm) for feed would seem adequate with a 10 mm return. Is the third to the canister?
All supplies
My fuel system uses 3 x valves at the tank and another 3 at the engine bay so it was easier to plumb this way.
2 x 10mm would have done it but I figured I'd go overkill and never suffer another delivery issue meltdown.
Last thing you want if you suffer a highspeed failure of any kind is a fuel leak potentially hosing fuel into the cabin while you come to a stop.
My big accident was a rearwards impact which forced the rear suspension into the full 120L aluminium fuel tank slicing through it like butter and to this day I don't know why it didn't catch fire. (I hit the battery kill switch just before impact)

man. rearend collision is something im very paranoid about. i mounted my a1000 off the rearend so it hangs kinda low (looks very badass when ur driving behind me though lol). but i used the painless a1000 install kit with all the appropriate relays and stuff. if i do get in accident, pump should cut off.

Okay, I am scared enough :eek3: . The aluminum hardline is going back to the store.
