Fuel Line Size

  • Thread starter Thread starter srg
  • Start date Start date
1/4 inch is 6.35mm, so close to 7mm that it's insignificant. 5/16 is larger and requires clamps for sure. 1/4 is a nice tight fit. I like it better than the 7mm.

I used to use them ALL THE TIME. Some of the guys might have even gotten tired of me praising them all the time. :oops:

Then I got shafted on a couple of orders. Called to check the status of an order, was told that everything was there, would be sent out the next day. I asked them if I were to pay the extra, would they ship it out that day, for next-day delivery. They said, "yeah, no problem". It was THREE DAYS before I got the stuff. I called on the second day to see what happened. The guy I talked to said that they had shipped it that day (the second day) for next-day delivery, not the day I had asked for. Since they had, indeed, spent the extra for next-day shipping, they were not interested in refunding my money. Since then, even though Beau (the parts manager) has assured me personal service, I have not returned.

I get better communication at all points of the process from Parts Outlaw, and that is worth the couple bucks extra for the order. :D

Tight is nice, but the only 1/4 inch fuel line you can get from any local stores is reinforced, heavy-duty hose for pressurized fuel systems, and it is that much harder to try to stretch over the fittings.

Continue with your 1/4" hose, if you wish, but if you ever try the real stuff, you will also become a believer. :-\\\

Would 1/4" starve the carbs at WOT and/or highway speeds?
 
So I really wanted clear fuel line. I happened to stumble upon this:

"Crack-Resistant Tubing Made with Teflon? ? PFA"
http://www.mcmaster.com/#5733k77/=rsxpl5

It's 7mm ID (9mm OD). Temp Range: -320? to 500? F. Chemically compatible with gasoline.

What do you guys think? It's slightly expensive, almost $30 for 5 feet of it. But I really want clear fuel line :-x
 
I go to Orelleys and on the blister cards thing for small engines is fuel line thats absolutely perfect for the fuel nipples and its like 2 FT for cheap. OK..so I just saw you want clear...its not but its good line. Kinda a clear/ matte finish i would call it.

Compatibility chart shows gasoline is okay. Post a review if you give it a go.
 
@srg

How'd the clear fuel line for McMaster Carr work out

I am looking into some 7mm clear fuel line too

thanks
 
WOW, there is nothing like resurrecting a thread that is over three years old. :encouragement:

It's a good thing. Bringing back an old thread means that someone is searching for info.
 
@Nessism. Thanks. That's exactly what I am up to.

I am Pulling the carb bank for cleaning, rejetting, and gaskets. Wanted to put it back together with new fuel hoses and vacuum hoses too. After some research, I've managed to nail down the fuel feed hose as a 7mm ID.

It seems I can use 3/16" ID black hose for the vacuum runs?? Is this correct

i do really like the look of the reddish clear hose for the fuel system
i found dime city cycles has it but it isn't in metric sizes.....
anyone out there have a source for metric sizes on this ???


thanks a bunch guys

There is nothing like having the proper parts here.

From Parts Outlaw:

Vent hose - 09355-45855-600

Fuel hose - 09352-70103-00B

Overflow hose - 13683-45070

With the vent hose and fuel hose, you will get one long piece of hose. The vent hose might be just enough to cut and use for both pieces that you need. The fuel hose will be about 6 feet long, which is MUCH longer than you need. I have not ordered the overflow hoses, and I can't tell from the description how long it might be. Hopefully the length that is ordered will handle more than one carb.

I understand that OEM is the way to go for parts/ gaskets etc..

Ive used part outlaw, bike bandit and partszilla many times; but I wanted to know if anyone had used an aftermarket clear or translucent red fuel hose before, and had been happy with its performance, fitment and longevity
thanks

That's a pretty generic description, not sure you will get pertinent info unless you can name the fuel line by brand and even then, not sure. Most of the cheaper aftermarket brand clear tubes get hard as they age. I'm sure there are exceptions though.

I used some off the shelf hose from Autozone. Goes on easier and stays on without a clamp after 2 years.

I think any hose designed for fuel will work.
 
So does anyone have experience with the red translucent fuel hose that dime city cycles supplies?
 
I just took a quick look at their site, I only saw 3/16" and 1/4" translucent fuel line.

The 3/16" simply will not work. The 1/4" might flow enough fuel, but you will have a hard time getting it over the various fittings on the petcock and carbs.

The red might look cool, but if you have to work that hard to make it happen, is it really worth it? :-k

That line will most likely be fine, but it will harden within a year or so and make servicing tricky if you have to go into the carbs again.

A better bang for your buck (my opinion) would be to use a good quality OEM fuel line and work on replacing your plug wires with some 7mm copper core RED wires if you want to add a splash of color. There is info in the archives about how to extract the OEM wires from the stock coils and replace them. For about $2/foot for red wire you can make a functional improvement (maybe) and add the splash of color you seem to want.
