Better fuel return hose

[stewardc]

I like this, but what keeps the hose braid from fraying with no fitting on it ?

sorry stewardc, only just saw your reply. you can just see it in this pic...

just some electrical heat shrink :-) I cut the braid back about 5mm from the end of the inner teflon, and then put a 15mm piece of heatshrink over the end of the braid.

I like clear lines between the injectors, for troubleshooting.

Im trying 1/4 air brake line, fits like a glove, looks cleaner and is super cheap, not every part store has it though, my local napa does but there the only ones, i think it was 1$ for 2 feet

[stewardc]

The line between the injectors is 1/8". Someone must make a better hose than that braided VW crap.

Others have mentioned using vacuum lines from gassers.

I'm using Tygon transparent-yellow 4040A. http://www.amazon.com/Oregon-07-151-Fuel-Line-Tygon/dp/images/B0086OE0EE

Polyurethane comes in blue... http://www.amazon.com/Raider-717B-5-Roll-Fuel-Line/dp/B002ZTGLFM/ref=pd_bxgy_auto_text_z

Many thanks. That's what I needed.

I ordered 15 feet of this. And 25 feet of this.

Flexible to -100F!

I just ordered these 2 part numbers. The smaller one fits fine, but the larger 1/4" - 5/8" is too thin. It doubles over and kinks too easy. I'll probably order something a little thicker.

I also ordered some spring clamps, but they mistakenly sent 16mm versions.   

I'll post up the part number if I find something. Thanks for the lead though!

The 4040A is yellow, but you can see through well enough to detect bubbles.

1/16 wall seems ok here.

I tried the blue poly. NOT good. It blew off on a full-throttle run and soaked the engine in smoking, almost-ignited diesel fuel. I went back to the old tried-and-true VW braided hose. It may look poorly, but it has never blown off.

It blew off of what?
 The pump output?
 Might have a clogged return line/check valve. There shouldn't be any pressure there.
 Did you use a clamp?

It will never catch fire, your safe lol. You can hold an open match to a puddle of diesel and it will not ignite.

There shouldn't be any pressure there.

There should not be any pressure between the injectors, or in any fuel line for that matter (except for the metal hard lines to the injectors).

 Right, that's why I'm wondering how it blew off.
 If you want to hose clamp the tubing it can pinch up and let more air in.
 I slide a piece of 3/8" rubber hose over the 1/4" ID tubing.
 Sliding the tube onto the barb then the rubber hose over that.
 A clamp works real well over the rubber hose,.. if one is needed.

 I'm a bit defensive about the blue tubing found at motorcycle shops. It works great for me.
 Throwing used motor oil in the fuel will sure make clear tubing hard to see through.
