TR2/3/3A Is 1/4" nickel copper brake line tubing suitable.......

for the gas line from the fuel pump to the carbs???

 

[Hamish Racing]

Not sure what mine was but my gut say it wants to be more than that.

I use copper-nickel 1/4" line for the carbs to fuel pump. Then it is 5/16" from tank to pump.

If for fuel, why not standard steel fuel line? I sense enough vibration and other factors in the routing of that line around the engine that I lean toward something stronger for fuel line. For brake line, I’d say the same, though I’ve seen copper for the short connector pieces at the front calipers.

Steel was the original. I have 3 TRs using the CU-NI with an accumulated 15+ years of use. I am still good to go.

Is the CU-NI fairly easy to bend?

Is the CU-NI fairly easy to bend?

YES. I do use some bending tools. But it is very forgiving and can even be rebent if wrong the first try.

My TF has all CU-NI lines on it. It is so nice to work with and as stated, very forgiving. I do prefer using the proper tube bender though and double flaring tool.

i also am using the C-N for fuel lines for 2 years now as mentioned above, it is preferred for its ability to be shaped more easily. Bruce

Is it necessary to flare the ends of the tubing for gas line use?
