You can buy them as stated above. And, they will most likely outlast the rest of your car.

If you want to replace them with Rubber Hose the ID is 1/4 inch.

To remove the Old Plastic tube put the Banjo part in a padded (no steel jaws, use aluminum or copper) to hold it. Use a Butane lighter to soften the plastic while at the same time pulling firmly on the tubing.
The object is to soften not melt the plastic.
If it is already broken off you need to soften the plastic and use a dull kinfe or something to pry off the plastic from the Nipple of the Banjo Fitting.
After that Fuel Hose + hose clamps.

A few members have used Tygon plastic tubing. In order to get it on you need to heat the Tubing and shove it on quickly. There is 1 or 2 posts that mention this but they are from about 3 years ago.

When I did a Spin-on Fuel Filter mod I had to move the Filter to the read an inch or so. This required a longer Tubing/Hose so I just replaced both Plastic Tubings with Hose.

I went with the Rubber Fuel Hose and clamps since it was cheap, available and I was not sure I would be successful if I tried the Tygon plastic tube.

The stock Spin-on Filter is a 10 nominial mircon filter. This means that it stops 50% of the 10 micron or larger particles on the first pass through the Filter.
The CAT 1R-0750 is 2 absolute micron Filter that filters out 98%+ of the 2 micron particles on the firs pass through the filter.
So the CAT filters out much finer particles and it is also at least 2 times larger than the Stock Filter.
So it protects your Fuel Injection Pump better than the stock Filter does.

I read about the CAT Filter on a VW TDI site.
The CAT Filters are $16-$24 each.
The Baldwin version BF7633 is supposed to be close to equal and cost 2/3 of the CAT.

Below is my old thread it includes my CAT Mod and Deliveryvalves Baldwin Filter Mod that has a Drain at the bottom.

Tygothane

Saint Gobain is I believe the manufacturer.
800-798-1554

U.S. Plastics allows you to order reasonable lengths.

(I cannot remember whether we'd use the ester based or the ether based)
(One of the two is Bio-Diesel impervious)
(I got started investigating when the local bulk fuel distributor went to 5%
Bio-Diesel...They've since dropped that as a Lubricant additive,due to problems
with FUNGUS infestation at the retail station level.Also the BIO D tax credit went away.)

It can be ordered with the "Diamond" crosshatching re-inforcement.

Tygothane® C-210-A Precision Polyurethane Tubing
Flexible polyurethane tubing that has consistently tight tolerances from lot to lot. Precision tolerances and high elasticity provide the user with an easy, worry-free attachment to fittings. Made of a tough, ester-based polyurethane. Tubing’s clarity, high tear strength and excellent abrasion resistance make it ideal for many applications, including fuel and lubricant lines, pneumatic lines, abrasive product transfer and cable jacketing. It also offers exceptional resistance to oils, greases, fuels and many chemicals. Able to withstand rugged daily use, Tygothane® precision polyurethane tubing resists weathering and can be safely used in temperatures ranging from -100°F to 200°F. It meets FDA requirements for food and beverage use. PIS listed at 73°F.

Tygothane® C-544-A I.B. Precision Polyurethane Pressure Tubing
More flexible than many other reinforced urethane tubings, Tygothane® pressure tubing can be used in some of the most physically demanding applications, such as those requiring a tight bend radius. Specially formulated from tough, ether-based polyurethane resin, Tygothane® pressure tubing is resistant to a range of chemicals, including oils, greases, solvents and chemicals. Because of its excellent wear properties,this tubing frequently outperforms traditional rubber, plastic and metal materials when exposed to abrasive conditions. Tygothane® pressure tubing is also plasticizer free, and remains flexible even when cycled through temperature extremes. Abrasion and tear resistant. Braid reinforcement for elevated working pressures. Flexible even in sub-zero temperatures. Meets FDA requirements. Meets NSF 61 requirements for potable water contact. PSI listed at 73°F. Max working temp 180°F.

I bought some of this stuff http://www.orangecustomcycle.com/WPS-FUEL-PRIMER-OIL-INJECTION-LINE--CARBURETOR-VENT-detail.htm?productId=9925547&ez=blue%20fuel%20hose
Are there any problems with this type of fuel line for use as diesel inj. return lines and/or the line from the filter to the IP?

Concerning use as Injector Fuel Return Lines

There is 2 comments from my notes. Not sure who said them; the first is the most recent.

1-Injector return hose plastic tube
any lawnmower/chainsaw repair shop should have hose that will work too.
I bought a 50' box of 1/8" tygon clear fuel hose and the stuff holds up for about 3 years.
cost me like 15.00

2-The brand I used is Oregon, it is a Tygon fuel hose.
Tygothane (Saint Gobain is the Manufacturer)
U.S. Plastics is the retailer.

I got the 1/8" and 1/4" blue polyurethane fuel hose today and - unfortunately the 1/8 is too thin walled for anything i'd want as diesel return lines. They easily bend just trying to push them on. The 1/4" looks thick enough to work as filter-IP line, but the 1/8" I would only use as an emergency fix. I'm sure it has other uses. (I'll keep some of both in the car just in case).

This tubing sells on Amazon (arrived in 3 days, free shipping)
