I am getting my rebuilt Carbs back in 2 weeks, found a retired Boeing Machinist who does it as a hobby, he said that most overlooked when carbs are rebuilt are the butterfly disks and they get worn, he also found my shafts were worn but not the case, so we put new shafts in and butterfly disc's. Funny thing is that they were rebuilt only 6000 miles ago, unfortunatley that was in 1987, so they were gummed up, someone had actually put the wrong shaft in one of them when it was rebuilt I guess.
anyway, I am at the point to pull the gas tank and am using the POR kit to clean and coat it. I also purchased a roll of fuel line thats bendable, I had run across a guy who made a wooden gig to straighten out the line since it comes coiled. I have since lost that info, but was made up of about 12 inches of 2x4 board with a groove down the middle, You then sandwich the 2 boards together with some wing nuts and pull the line through ( I am guessing it would be easier it the gig was attached to the floor or wall.
anyone done this?
also If I pumped some clean fuel through the original line and then used a new fuel filter inline would i be safe to just do that?

Thanks
sorry for all the typo's
 
Hi yes I have made a couple out of the rolled up tubing for tr3s. The 1961 tr3 fuel line is the same as a tr4. Anyways the line is not that long and it is in two pieces maybe7 feet and 4 feet. Use your old one as a pattern lay that on a bench. Get a kinda good tubing bender and tubing cutter. “Let the new pieces run long foot or so” Now take your foot and put that on one end and start unrolling the tubing when you get plenty unrolled cut it. You can actually use some of the arcs to your favor as you bend the line. You will probably screw the first one up but that stuff is cheap. The first time I did it, I made about three before I got o real nice one.

Looks like you 2 should get together and do this.
 
Just made a new set of fuel lines for a TR4A IRS and the hardest one by far is the longish part that traverses the drive shaft well.
Not terribly hard ... Buy a roll of fuel line... I made three before got one to match original well enough.
 
If you buy the fuel line kit from VB you pay $60 for a 8 ft roll of copper tubing you could at any hardware store for less than $20. Does work good.

Oh my... I would not use copper line for this as it is too easy to break due to vibration fatigue.
Use a soft steel lines from a local auto store... approx. $30 for 30 feet.
