But, Those same OEM Nylon fuel fittings are used on the past decade of
Corvette's, Z06's, Shelby GT500's, SRT8's, etc. So for my purposes, they
should be cool.
Also know that the nylon stuff doesn't go any bigger than 3/8. Not a problem for 90% of the swaps, but will be an issue for the serious HP machine.
As for the "serious HP machine" that's true for in excess of 700hp or more+ For my application, I'll run out of fuel pump (Walbro 255) before I run out of fuel line capacity. LOL
I'm sure guys that want a drag toy will spend the money on compression fittings or AN fittings with Teflon or Steel lines. JIC spec are good too. AN is just Air Force / Navy standards from WWII to today for Aircraft. We're not flying military aircraft.

True.....

I noticed that too.

I actually agree with you and for the most part like your approach. Your set up will build you enough motor to get jailed if you drive it like you stole it. But IMO you are off in some of your assumptions. The pump capacity and fuel lines interact. If you aren’t careful you can turn your 255 L/hr pump into a 100 L/hr fuel system. To use your analogy use a bunch of restrictive fuel fittings and you will run out of fuel pump before you run out of fuel pump.
According to this link below anything much over 400 HP needs ½ inch fuel line. Also keep in mind the numbers in the link below assume non-restrictive fittings and not the ones in that Dorman kit.

Here is what Mallory recommends with their fuel pumps

So by serious HP machine I was thinking anything much over 400 HP.
One trick you can use is run two 3/8 inch lines instead of a half inch. ½ hard line is pretty difficult to work with, so that trick works even with steel line.
