Prefered Fuel Lines

Thinking a little ahead, I will be looking to purchase fuel lines in the near future. This will be for my 03 6.0L truck which will be swapped in my 64. If I'm not mistaken it will need 3/8 pressure with a 5/16 return? Looking at recommendations for type, steel, nicop, braided? I know at some point the hard lines will have to convert to soft, would it be easier to use soft for complete run? This swap will stay mostly stock, also looking into Tanks Inc. My build is currently with the frame on jack stands and powder coated and most of the suspension is installed, motor is not installed. I welcome all comments.

Re: Prefered Fuel Lines

I would use some type of hard lines along the frame, I used a pre bent Right Stuff steel (wasn't SS) 3/8th" for my BB

Re: Prefered Fuel Lines

I'm running a Tanks, Inc. setup with steel 3/8" inlet and return the entire way other than a foot or so on each end to connect to the tank and fuel rail. I used reproduction prebent lines and cut them in the rear; I rebent the front to run up the firewall instead of through the frame so I wouldn't have to flip my fuel rail.

Re: Prefered Fuel Lines

I ran 3/8 Nicopp with premade teflon soft lines at each end. Can't say as to if it works well or not yet...but hopefully I can answer that in the coming months.

Re: Prefered Fuel Lines

Stock style nylon line. Flawless and easy. A few bucks worth of fitting and line that is dirt cheap.

I used 3/8" nylon for everything, even the 5/16 connections. You can get 5/16 fitting with barbs for 3/8 line. BUT putting 3/8 nylon onto 3/8 AN barbs is MUCH harder than onto the plastic quick disconnect fittings or other stuff. I may remove the one I did and use something else on that one fitting.

Re: Prefered Fuel Lines

Michael,

Tanks Inc makes a filter/regulator similar to the Corvette unit, at less than 1/2 the cost. The unit mounts near the fuel tank and eliminates the need to run a return line from the engine.

I got mine from RockAuto, looks identical to that, even the ground wire. And that fitting they show male-male disconnect to AN-6 is what leaked for me. I replaced it with a 3/8 male quick disconnect to 3/8 nylon barb connection.

This would require changing the fuel rail. Not worth it in my opinion.

Maybe not, should work with just plug/capping the return fitting from the rail.
Also, like I mentioned earlier, even if something is 5/16, you may be able to buy all the same 3/8 line (whatever you choose) and use 5/16 fittings on the ends that connect to the return lines. May save you in the long run, and help when/if you goof.
An example https://www.dormanproducts.com/p-164...origin=keyword
And installing those connectors on tubing is not easy, but not hard either. And NO HEAT IS NEEDED. I watched a ton of videos, and almost all use heat gun/boiling water, and that way softens the nylon tube, I don't trust it. The Dorman tool presses the fitting in cool, like a caulking gun. I made a split block to hold the tubing in my vise, put a socket with extension over the end of the fitting to spread the load. Then I used spray silicone (REALLY HELPS) and worked the end of the tubing a bit with a rod to open it a smidge, then just pounded the fitting right in, easy peasy.

Re: Prefered Fuel Lines

Also, when using those fittings, put the colored clip on the steel line, then push the fitting over the line and clip, same as it comes apart. (Color matches the steel line size, green=5/16, blueish 3/8)
