Fuel System Plumbing Question- Proper AN Hard Tube Adapter Use ?

[kitcarbp]

Here is one correct solution when connecting your hard steel line on your chassis to flexible steel braid -6 AN line on your engine.

Using a 3/8 inch Terne Coated steel line on your chassis, I used $ 2Aeroquip -6AN coated steel compression fitting with a coated steel $2 -6AN male union. Then found a $ 7.50 coated STEEL -6AN hose end from Earls AUTO-FIT product line. I could have also purchased the 37 degree flare tool but since I only had two flares to make on either end of the chassis, I decided to use a compression fitting instead. Gas line to hold no more than 8 psi for my system pressure so this will work. Make sure you use good quality gasoline/fuel grade steel flex hose that has a co-extruded inner vapor barrier otherwise you'll wonder why the garage smells like a pool of gas. There is a lot of aftermarket junk out there for steel braid hose, be careful and happy plumbing.

You dont want to mix aluminum and steel connections and expect a long term reliable joint.
