Q & A

What's in the Box

Where else can you buy aluminum fuel line in the size and length you need? This easy-to-flare and bend tubing works great as AN hard line and will save weight and money.

  • Use with tube nut couplers, sleeves and 37° flared AN fittings
  • Rated to 250 psi
  • Not recommended for high pressure (brake) applications
  • Available in 10 ft., 20 ft., or 30 ft. coils

Learn more about flaring hard line and how to select proper automotive fittings by reading our tech article, The Principles of Automotive Fittings.

Notes

The main issue when dealing with aluminum tubing (or any aluminum for that matter) is that it “work hardens” when it flexes, which can lead to cracks. It is important that the hard line is isolated from vibration and movement.

Clamp the tubing securely with rubber coated clamps (Adel clamps) and use bulkhead fittings where the tubing attaches to the flex line. Never run the tubing directly to the engine without a flexible hose section. If installed properly, aluminum tubing is safe and durable.

Works very well for antenna projects!

December 20, 2015
I used this fuel tubing as the outer diameter of my capacitance hat on my vertical HF antenna. It runs through holes I drilled into the aluminum rods I used for the cap hat and works very well. It's easy to bend, shape and get into the antenna.

Part # 91011429 This aluminum fuel line will handle up to 250 psi which is more than sufficient for your natural gas application and should work fine. It can be 37 degree flared or used with the standard compression fittings.

You state this fuel line is OK up to 250psi , and then state not suitable for high pressure ??? I need it for fuel feed from a 120psi pump to a 450hp LS1 engine , and people seem contradictory as to its suitability ?? please reply

This aluminum line is OK up to 250 psi so your 120 psi requirement is well covered. We recommend the 37 degree flare with the appropriate tube nuts and sleeves for a secure fitting at the higher pressures. The aluminum line is NOT recommended for high pressure applications such as brake lines where pressures as high as 1200-1400 psi are common. In those cases a steel or stainless line is recommended.

I wanted to make sure this supports 250psi, I read other places that aluminum is good for only up to 25 psi.

As long as you're running a carb,not fuel injection,no fitting will be needed.I ran this line from the tank all the way to the fuel pump on a 289ci with a short piece of flex line at each end and a hose clamp.No leaks ,no problems. I know you can get a lot of misinformation on the internet,but I,ve been building street rods for over 40 yrs.

I would not clamp hose to aluminum line, there is no barbs to help hose from slipping off. I would use 61763921 and then part #1061222.

Earls 008ERL EZ-Beader Tubing, 3/8 Inch Tube O.D
(Part #425008ERL)
                        

Earl's patented EX (Roller) Beader is a fresh approach to an old problem. In order to securely attach rubber water hose to rigid aluminum tubing, the end of the tubing must be beaded. Generations of racing mechanics have used military surplus Parker beading tools to do the job. We probably sold more of them than anyone. Unfortunately production ceased after WWII and the surplus kits have been scarce for over a decade. Compact enough to be used on already installed tubing, Earl's EZ-BEADER produces a properly positioned and perfectly radiused bead on aluminum tubing with wall thicknesses from .035" to .065". This is one tool that no serious racing mechanic can afford to be without.

  • Fresh Approach To Old Problem
  • Attach Rubber Water Hose
  • Properly Positioned & Perfectly Radiused Bead

Deluxe Flaring Tool, 37 Degree AN
(Part #91089528)
                        

This is the tool you need to make the 37° flares required for AN fittings. Standard brake and fuel lines are flared at 45° which are not compatible with AN hardware. This tool forms stronger flares assured by a smooth, even radius formed at base of every flare with its precision machined chamfer. Plus, its also self gauging - just insert tube flush with top of die for accurate flare size.

  • Hardened steel, chrome-finished cone makes exceptionally smooth, high-strength flares with a radius at base of
    flare – instead of the sharp angle formed by ordinary tools
  • Slip-on yoke permits use in tight quarters
  • Allows flaring where there is little space between nut and tube end
  • Feed screw design provides smooth, easier operation
  • Positive gripping and self-gauging of tube for exact flare size
  • Sliding die blocks lock in place by clamp action

Works on 3/16", 1/4", 5/16", 3/8", 1/2" and 5/8" OD tubing such as aluminum, copper, brass and mild steel.
