Replacing windscreen washer lines

Tim: having just done this on my 65 Coupe (with the help of the JCNA hotline and Georg), it is not to be taken lightly. First off, if you want to replace the lines, then you will want to replace the sprayers as well. You will, without a doubt, require the services of a child with incredibly thin arms. There is no any way around this. Preferably 10-12 years old as they will have the mental capacity, physical attributes and the fortitude (with bribbing) to be able to pull this off.  The parts you will need are the hose (min 8ft), the "T" and the 2 windsheild sprayers. I got mine from SNG. The hose is cheap so you can get it from them or an aquarium supply. 

1) First you have to pull the center console and then lower the gauge/fuse panel.

2) As you look into the dash, you'll see the arms for the wippers. You need to pop-off the wiper motor arm connection that's blocking your way. BEFORE you do that, tie a string around the arm so when you drop it behind the dash to get it out of the way, you dont lose it.

3) Next it's fairly common sense. This is where the kid comes into play, also. Your helper will have to follow the lines up to the sprayer. Way easier said than done. There is a wing nut of stamped steel (pretty cheap actually) at the bottom of the sprayer that they will have to remove. The drivers side seemed easier than the passenger side, so you may want to start them on on that side to get used to how things work. You will have to hold the sprayer while they remove the wing nut. Once removed, you can pull the sprayer straight up. Pull off the hose and tape the new hose to the end of the old hose you you can pull it back through.

4) Repeat for the other side AND the firewall. make sure you get at least 8 ft of hose. You will have plenty left over.

5) I had my helper take the new wing-nut and once on the new line, follow it back up to the new sprayer base, which you are holding firmly in its mounting hole. This is fairly tough because its fairly difficult to have the dexterity needed to thread the new wing-nut on correctly and tighten it down. Especially on the passenger side.

Tips: Put the "T" on after the drivers side is done. Make sure you have enough line on the separate connections to compensate for the slack needed to set up the "T" and everything behind the dash.  I set up things so I could pull the extra slack out of the system from the passenger sprayer hole and pump/firewall connection. I also used a blow dryer to slightly heat the tube ends to slip on the new sprayers and to the pump. 

This whole process took a couple days what with trying to get my girlfriend to take a stab at it first. That was not a great idea. There was also the additonal time and associated cost of dinner out on the town to assuage her bruised  arm and chipped fingernail polish. Rounding up the kid was another 12 hours and 20 bucks. All in a fairly low cost project....in the grand scheme of things.
