Title: Good, flexible, clear tubing for fuel lines.
Post by: 8v-of-fury on January 23, 2012, 08:27:05 am
I was just wondering what people were using for their clear fuel lines. I have some fuel rated clear lines in my car right now and they are beginning to get hard and not movable anymore.

I would like to retain the clear lines throughout the engine bay, as I like to see what is what.

So, what are YOU using :).

I use transparent polyurethane fuel line from motorcycle shops. Holds up good when running bio fuels as well.

Libby found a great supplier of Clear Fuel Grade Tygon (friendly prices) a while back.
I had bookmarked the thread - and its gone.
Guess he originated the thread - and it went with him.

Seems like it was in Arizona.
Car Masters / Auto Masters / McCarMasters AutoMcMasters ..... or something like that. They had a website.

Some of it you had to buy certain footage.
I bought into some with him on the injector return hose size.
VERY VERY TOP NOTCH.

But i don't have much left of it anymore.

==========================

I had been using translucent yellow tygon on injector returns, purchased from small engine repair shop locally. The clear from Libby's place seems even higher grade - and its clear. And it was less expensive too.  ;D

Meant to place an order for fuel supply/return sizes and never got around to it. Libby bought those sizes and had use for the amount ordered. He loved the stuff too. So its good.

Been using cheap clear tubing from Tractor Supply / Lowes Hardware on fuel supply & return on several cars. Some of it is going on 3 years and it gets rather stiff in Winter now. In case anyone is reading - it won't suffice on injector returns - but does well enough on larger hoses.

Later or sooner, i want to get on the ball and refind that supplier and get the better stuff.

Most likely McMaster-Carr... mcmaster.com (http://mcmaster.com)

They have good prices on viton by the foot as well.

wow, I have never heard of that mcmaster website before! Where have I been living!?

For future reference in this thread, what are the needed fuel line sizes? What are the barbs on the fuel filter and injection pump for the feed and return line? the size is 7mm or 8mm for the return lines between injectors isnt it?

Post by: Luckypabst on January 23, 2012, 06:12:44 pm
I'm pretty sure I used 1/8" for the small return lines.
Used to be Mcmaster was cheaper than Greaseworks, but not true anymore. So, I'll also suggest Greaseworks for viton (but that doesn't answer the original question, though).

Thanks for hooking us back up with the link Luckypabst.

We were using Tygon, not Viton.
They had great Tygon prices that i couldn't beat anywhere.
But that was probably over a year ago.

Injector returns are universal... 1/8" ID
And get the thick wall stuff

On everything else, i'd recommend each person take their own measurements. So many variables and mismatch / hodgepodge.

The Tygon has great stretch and grip ability.
As in practically no clamps were even needed - according to Libby.

Some folks will want Viton
if they intend to run Heated WVO

I did everything, but later pulled the injector jumpers off.  They didn't fill up and I thought it looked stupid.

I think I used 1/4" & 5/16".  The stuff I used was more rigid like the factory stuff. I got everything from mcmaster.com.

Yup. I was also suggesting Mcmaster as a source of Viton for folks that like its broad fuel compatibility. I don't know much about Tygon.

ToddA1  Did you run that line all the way back to the tank? I have been looking for a suitable replacement, but didn't want to use the Tygon as I figured it could get kinked as it is very flexible. Also a run of it that long that I couldn't see I would wonder if it would collapse on itself from suction and I wouldn't ever find it.

Tygon should have the same broad fuel compatability as the viton. I could be wrong, but have heard it is the same stuff with a different brand name, or real close to the same stuff.

No.  If you look to the left of the air box, you can see some black braided line I used as a coupler.  I merged to the clear with some nylon barbs.

Not sure what you're looking at, but there isn't a kill switch installed. 

The only thing that's out of place is the fuse holder on top of the washer bottle and the Ford starter solenoid and GP fuse holder on the raintray.

I got it.  Should the car not be able to start the cable comes off, gets wrapped around the bumper supports and becomes the tow it home cable.  Genius.

When I say this stuff is flexible, I'm not joking.  It's like a wet noodle.  I compared it to some some 1/0 Streetwires, and it was a totally different experience.  There's a really tight hair pin bend under the battery tray (service loop) and the Streetwires stuff would have never done that.  Comparing the two, the Streetwires stuff also seemed undersized.

The fuseholder came from the same place.

I used 1/0 as well, but not transparent. Super flexible fine wire, good for starting.

This seems to be the case where more is better.  5400 plus wires and it can handle up to 300 amps.  That should do for just about any of our GP, starter needs.  Maybe some subwoofers would press it. 

Nice product.

How is the jacket on that wire? I would just be concerned with the positive cable sitting the negative post longterm unless your dubs vibrate much less than mine! or is that a illusion they are that close in the picture?

How does the plain old clear vinyl fuel line hold up longterm?

That stuff is rated to 375A @ 20'.  I've run some pretty powerful sub/amp combos in my younger days and I can assure you that I never came close to maxing out my 2 ga. wire.  Touching on an earlier comment I made about Streetwires looking undersized is partially true.  I just read that the cable I used is purposely made oversized.

The spec sheet says the insulation is 2mm... slightly over 1/16".  It's an illusion about any contact; the cables are on an upward sweep at that point; they were at least 1/2" away from the negative terminal.

Back on topic about the lines, lol.  I used    5384K604 (3/16" ID 5/16" OD) and 5384K57 (1/4" ID 3/8" OD) Moisture-resistant Polyethylene Vacuum Tubing.  I just saw that it's not recommended, but I drove the car for at least 6 months with those lines on it and had no issues. I guess you're taking the same chance if you use the clear vinyl tubing.

Not sure if I made a mistake when I ordered it, but I should have used 50375K45 (3/16" ID 5/16" OD) and 50375K47  (1/4" ID 3/8" OD) High-Pressure Polyethylene Vacuum Tubing.  From the rating table for diesel: No Effect—Excellent chemical resistance. No performance degradation.

I had one of those till one day I got on it, stripped the threads, and blew my fuel all over the street :-[
I think some of those are more equal than others.

I just replaced some  cross weave reinforced ?nylon?  from the hardware store after 5 years.  It wasn't causing me problems, but wasn't as supple as it used to be either.

I've got almost 3 years on some of the cheap vinyl (10-20 cents per foot) from like Lowes/Tractor Supply/Hammerhead Hdwr. In use just underhood, on Supply and Return.

On injector jumpers, and from Inj Pump to Injector, i use thicker walled tygon.
The 1/8" vinyl is too thin walled and it splits on the ends.

The vinyl "might" go 5 years.
Have it on 4 cars so far.

what is it and where did you get it? is it a mini filter?
Title: Re: Good, flexible, clear tubing for fuel lines.
Post by: ORCoaster on February 27, 2012, 07:54:06 pm
yep, little mini filter inside a glass cylinder with o rings on either end and caps with hose bibs on it.  Check any automotive store or parts counter.  They are like everywhere.  I own one that must be 20 years old now.  I know that because I had it on my 1980 Ford F150.  Watch out all you youngens, when your kids go to driving they think they are magicians, turned that truck into a telephone pole.  Totaled it.
