Here is a write up on my switch from a hose to metal gas line. While the hoses were of the correct type and new I decide to replace to metal for safety reasons. I had previously swapped out a Non-original leaking Holley carb to a new Holley 670 cfm street Avenger and installed with a Mr. Gasket Fuel Line I already had but it only accepted a hose. As I already had engine/compartment apart for upgrades and clean up it made job a little easier. While there a probably many other solutions and better and cheaper I thought this would help others or at least be a starting point.

I read Lars document on Fuel Lines, which I recommend before you start to see what tools you will need and how to use them.  Also has some great examples.

I started out with a 40" 3/8 piece of fuel line and cut in half and ended up using both piece as the first was off by 1/2 inch in length and had to be scraped. Start with a coat hanger or some 1/4 or 3/16 brake line that are easier to bend/shape. I use some old 3/16 brake line for my mock-up and still got the 1st copy wrong.

As far as the fittings go, the fuel line I use on the carb has a outlet of 3/8 NPT and the Fuel Pump outlet is 5/8 - 18 inverted flare. I could have use the fitting supplied with the brake line to go directly in to the fuel pump but you have a big bend to clear the lower radiator hose. So I elected to use a 90° swivel fitting which provide ample room. So I went from (starting at fuel pump) 5/8 - 18 Inverted Flare to -6 AN all the way up to the 3/8 NPT on the carb fuel line.

Note: Fuel Line SUM-G3120 has replaceable fuel filter.
