Fuel Line

Player#3 · Jun 16, 2014

Hi,
The plastic fule line between the two carbs has started to leak. It is old and hard and cracked.
It seems the plastic tube is somehow crimped into the banjo fitting holding the filter.

Can this tube be replaced or must you just replace the whole assembly 06-5192.

Regards,
Sean

You can buy the parts including the ferrule but ideally need the tool to crimp them to the hose/fitting.
I couldn't see them but Andover Norton or other Europe based British bike part retailers should have them also since they were used widely.

That gives the option of using Ducati type fuel line if clear is regarded as bland.

Hey Time Warp, where is the best place to buy that green hose, I'm sick of the clear turning yellow in a week!! Also does anyone make fuel line in Blue?? Thanks, Glenn.

You can buy near any colour/color fuel hose you want from MX parts stores,it will metric but shouldn't be a problem ( ? )

A search showed plenty of the green Ducati type hose here in Australia including ebay but Moto Guzzi or Ducati agents should have it or maybe the Bevel Heaven web store or US eBay.
The sizing I'm not sure of, I think Pete V used some but that might have been on a Mikuni.

I was taught to use boiling water to rebuild fuel line sets. Basically cut all the new pieces to the right size. Take the old hard lines and dip in boiling water. You can pull it apart very easy then, including removal of the ferrules. then revers the process. Slip the ferrules on the line, heat it a bit in the boiling water, and push back together. Once cooled it's on there for good. Mine has been on now for 8 years or so although it's getting ready to be redone again.

Easy Peasy.

Great tip! Having been thirty years ago since replacing lines, I'd completely forgotten about how it was done. 'Works great!

I used the clear line from Old Britts, crimped the brass ferrules on with a flaring tool. Looks like original without being hard and yellow and it's 3-4 years old by now. Taken on a blue tint inside from the avgas. Kinda matches the bike. I did finally got some 180 deg banjos and got rid of the H style harness though.

You might want to look into Tygon as well, lasts forever - stays flexible. Available in clear and yellow.

An advantage of the 180 deg banjos is it also keeps the fuel lines a little further away from the cylinders - less chance of boiling the line dry when you stop a hot engine.

This is the stuff. I've tried it all, always marvelled at 25yo Jap fuel lines still in great condition. This is available black or gray. http://www.motionpro.com/motorcycle/too ... o/12-0052/
Available at FINER bike shops and most online bike stores.

I replaced mine several years ago with a piece of fuel line with no problems, so far. you can put hose clamps on also if you wish. Just be sure the hose is the correct length.

To bad we don't know where you are from. Your fuel problems would vary.
Here in the USA where there is almost no straight gasoline to be had, we are mostly stuck with E-10.
BIG DIFFERENCE!!!!
IMO..Clear or fiber reinforced PVC has long been seen as a bottom of the barrel fuel line.

Tygon is in the PVC family but is way above clear. yellow tygon 4040 is what I prefer for E-10. There is one other formula that is as good but I don't know the number. The light purple one is probably it...

I also use otkier pinch clamps

I just did a line for a guy with a 73 750 commando. Cheap easy and will last for well over 5 years. He was very happy with the job .My combat's tygon fuel line is over 15 years old and is probably softer than a new clear PVC.

I like the yellow Tygon also. It stays flexible and after a year or two it fades and starts looking like stock ones that have been used a while.

The already-made-up lines seem way too expensive unless you have tried maintaining any modern bike.

Thanks for the tip. I updated my profile.

Location: Vaasa Finland.

We have E-5 and E10 flavours available.

I HAVE never been in favour of the see through plastic fuel lines as they all seem to go hard and break. I use decent neoprene reinforced hoses, and have always fitted them to the cars and trucks I have worked on. They are black and look the part. You cant see any fuel going through them, and besides, you should keep your eyes on the road,[ and the birds of course. ]

My line just started leaking, since I changed my tanks to and the old one is brown and stiff. What is the correct ID/OD for the stock line (I am at work and cannot look see) as I just want to replace the hose itself onto the existing ferrules?

McMaster-carr.

Clear Tygothane Polyurethane Tubing 1/4" ID, 7/16" OD, 3/32" Wall Thickness, 5 ft. Length
http://www.mcmaster.com/#5549k47/=tgwmc8

I just had 5 feet delivered for under $20. I've had it on my Commando for a couple years and it's still clear and flexible.

gortnipper · Aug 27, 2014

Thanks. McMaster wont ship out of USA, and once they find you are out of USA, they blacklist you.

I will find something that fits that locally.
