Fuel Line Choices

I am looking at all of the aftermarket choices for fuel line. I would like to spend my money wisely, so, I thought I would ask the group. The rubber line looks like the easiest to work with and the claim is it is resistant to ethanol fuel. The other end of the spectrum is the PTFE stuff which seems a bit more challenging and more expensive. I will have to run an supply and return line about 20 feet total plus a line to throttle body for a total of about 26 feet. Any recommendations?

Re: Fuel Line Choices

I would not run that much hose. Use hardline with short pieces to interface to it. Nicopp bends easy.

I use Holley Vaporguard hose and AN fittings.

I used the PTFE cloth covered fuel line on my car.

Re: Fuel Line Choices

I did the same a Mr. Don. I ran 3/8" NiCopp line. I bought a 2 feet section of stainless steel braided, PTFE hose, Russell, part number 658520, to connect to the gas tank to the hard line and a 1 foot section for the engine side. Bending a long continuous hard line is difficult. I used two sections of hard line. I joined the two with a fuel filter between them. The cost of the AN fittings can add up quickly. I used coat hangers to practice and to see how it was going to look under the car.

Running the entire length with flexible line is a viable alternative. Many people do it. It is easy to thread the line through tight spaces. The hardest part is fastening the line to the car. Some people just use plastic wire ties. I don't recommend using plastic wire ties. The plastic deteriorates over time. Some flexible fuel hoses will allow gas vapor to permeate through the lining so the car will smell like gas. I think you know that Ethanol will destroy some types of flexible fuel lines. Manufacturers of PTFE hose claim that Ethanol will not harm the hose and it will not wick gas vapors.

The cost is about the same between flexible and hard line. Consider the cost of the tools to connect the fittings to the line and the cost of the fittings.

Money can't buy you happiness but it can buy you car parts which is bout the same thang.

Re: Fuel Line Choices

I am liking the idea of running the Nickle Copper hard line with flexible TPFE line at tank connection and throttle body. When you transition from NiCopp to TPFE do you need to flare the hard line? Does the NiCopp cut easily, and with what tool?

Re: Fuel Line Choices

I run nylon braided PTFE lines all the way and secure them with Kugel line clamps. AN fittings.

Nice and neat. Allows single line from tank to fuel rails or throttle body eliminating multiple connectors.

I use these:

Nicopp cuts easy with a tubing cutter.

Re: Fuel Line Choices

I went with the Holley vapor guard kit on my 68. Easy to work with and I secured the line about every 14-18" with clamps.

Re: Fuel Line Choices

NiCopp here, but I flare with a RIDGID 37 degree flaring tool and use tube nuts and sleeves
