What are your thoughts on running flexible fuel line from tank to filter to injectors? I have to re-route the fuel lines on the 37 to get them away from the exhaust. Currently 3/8" aluminum tubing. There are also two kinks in the line from the original builder that are severely restricting fuel flow and new fuel lines will clear that up as well. The fuel line has to be able to handle the pressure in the 65 to 75 lb range and rated higher. Also, what size would the 3/8" convert to in AN sizing? Alternatives to braided stainless to help keep some of the cost down? Thanks for the help.

FI hose is what I use to run from the frame to the rail and in any spots where I need it. To pretty it up you can cover it with the braided hose look-a-like covers. Willys33 is right on with the 3/8" supply and 5/16" return, that's what GM uses.-Brant

I don't do much work with AN sizes but I believe (probably incorrectly) that the 3/8" corresponds to a -06 AN. I believe the conversion is 1/16 = 1 AN. Why the minus sign (-) is beyond my reasoning capacity and I don't know the significance of the 0 in front of the 6. Some intelligent life form greater than I must have come up with this stuff. Not sure I will ever really understand this stuff.

I use 3/8" brake line myself . Return could be 5/16" but I just use one standard size. Godman and several other companies sell the adapter to hook to your GM style fuel fittings. Don't forget to use a piece of flex line from the frame to the engine. You can get that at your local parts store but make sure you ask for and get FUEL INJECTION HOSE. Will say so printed on the rubber.

I use 3/8" feed and 5/16 return steel lines on my RamJet engine. The last 24", from the frame to the injector rails, is #6 braided stainless hose. However, I have seen stainless braided hose bleed through and actually leak fuel after a few years, so check them every so often. Also, consider an inertia switch between the fuel pump and battery supply. In the event of an accident and fuel lines are ruptured, your fuel pump is automaticly shut down. Just think if it wasn't!! I have a Ron Francis unit. Easy to install and can be used as a theft deterent.

Thanks for the input. You've convinced me to bend (or attempt to bend) new hard lines. There is flex line from the frame to the engine so that's not an issue. I'll replace the 3/8" feed line and use the 5/16" for the return line (also has kinks). Wonder how much line I'll waste until I get the bends right?

The best fuel line is conventional steel fuel line. Stainless is good too but hard to work with. Flexible line should be supported every 6 inches or so with a clamp to eliminate swinging and abrasion.
