Petrol pipe

Managed to damage my petrol pipe. Anyone know what material are they made from? I have some thin brass tube I am thinking of soldering over the damaged section to repair it if it is compatible. Other than that I was wondering if copper brake line might be a suitable replacement solution?

Re: Petrol pipe

I used malleable copper pipe, sometimes sold as soft copper tube. It's used in the refrigeration industry and is available in all the usual imperial sizes. Lots of the car restoration people sell it (or ebay)

It's easy to bend by hand or round a former.

Re: Petrol pipe

Soft copper tube is spot on. I have used it before and it is easy to use and cheap to buy.
Google frost restoration for mail order. Or ebay too.

Cheers gents. Thanks for the quick replies. Looks like I have a job for tomorrow! :-)

Re: Petrol pipe

But you can still solder a piece of brass tube over your break if you just want to effect a repair. Ron

Re: Petrol pipe

I used a product called Kunifer (I think that's the correct spelling) which is usually used for brake lines. I think the benefit is that it doesn't 'work harden' as easily as normal copper tube. In saying that though, the stuff I had on my bike lasted 74 years without any major issues!

My main problem was soldering the T junction. It's tricky to solder all joints without messing up one you've already done. But then I'm not a great at soldering. I after 4 attempts I soldered the tap, and carb ends, and gave up with the one at the junction and bought a neat brass compression fitting, normally used I think for brake lines again. Will certainly make cleaning much easier in the future.

Re: Petrol pipe

Could someone post what the petrol pipes should look like for a 1941 bike. Mine are from Halfords!

Re: Petrol pipe

Thanks Ron.

Re: Petrol pipe

I have always wondered, does the spiral in the tube serve any purpose?
Or is it just the most convenient way to route the line from the tank?

Re: Petrol pipe

It's done to help take up vibration between engine and tank. Ron
