Triumph TR6 - FUel line diameter

So I need to replace the steel fuel line. Any body know what the diameter is? I thought it was 5/16. Thanks
A Vandergoot

It is
Before the pump 1/4 after

Unless I have that backwards.

Don,
Classic Tube is expensive. Anyone have other sources to suggest? Not only do I have to replace my fuel line, but the nylon vent line too. Sources?

I found the vent line locally
Expensive but sweet.
If you spend 15-20 large on a resto,why not?
Don Kelly

Yup 5/16. I will source some tube locally . I have to admitt classic are pricey local has SS tube for $5.25 a foot. Granted you still need to bend it but I note the original tubing is made up of 3 pieces connected with rubber/neoprene tubing.
A Vandergoot

Watch your wall thickness and material condition as this will impact your bending capability, you want to make sure that you get annealed material. Something else to consider is that 5/16 or a -5 in tube speak is sort of an oddball size and this can impact your tool selection and cost. As far as benders go, I like the Imperial tube benders, which a quick look at the interwebs says can be procured from Newman Tools and I'm sure there are other sources as well.

One of the tools is the Imperial 470-FH whcih will do multiple sizes, including 5/16" but is wall thickness limited to .032" max when used with austenitic SS like 304, 316, 321, 347 and such even in the annealed condition. Since for the most part the bend angles are relatively small in this application, this tool would likely do the job for you. If not and you need more "oomph" in the bend process, you have to up the ante to one of the bigger tools such as Imperial's 364-FHA-05. It is size specific as are all of the Imperial benders in the 364 and 464 family and this particular one is sized for -5 tubing. I prefer the 464 family over the 364 family, but size coverage is limited in the 464 family with no -5 bending tool in it. Bend radii is fixed with these tools but is typically in the 2 to 2 1/2 d range.

Something else I would recommend is to make a mock up in aluminum or copper first. The tube stock cost less than the SS and is easier to work with/bend compared to the SS. You can use it to make your notes and adjustments on distance between bends, bend angles and clocking of the tube in the bend tool so "Point A" and "Point B" end up where they are supposed to be.

Ton's of places to source tubing in most towns with two mules...get some...fill it with sand...tape it off and bend it with a $1.50 tubing bender (or your hand) gee'z O' pete you guy's can make the simple = complex..I'm sure BMC and Leyland went to such trouble!
JT White

Well JT, you're are entitiled to your opinion on things. I am familiar with the "fill it with sand and bend it" method, but have found that for long runs or short distance between bends situations or fitting requirements near the bend tangent point that it is somewhat lacking. It also does not tend to work that well with the (nominally) higher strength tube materials such as austenitic SS that the OP mentioned even in the annealed condition relative to the typical 3003 or 5052 aluminums or copper tubing.

For this particular application, making any individual bend is not that bad, the problem is putting the different bends together in one long length of tube stock. The short hard line bit at the tank and the short hard line bit at the fuel pump inlet are not the difficult part. It's that long section that runs from behind the axle line to under the engine compartment along the frame. Given the length of the tube run involved and the shape of the run along the frame rails, getting the bends in the right places, at the right angles and properly clocked is key to making it all work.
SteveP1

Still say Classic tube.
At least it's done right.
It is pricey I admit.
But I think I've wasted that much in tubing cost alone

Mr A.V. Is Octagon Motors in Vancouver not near you?

You must also know Len Drake of Drakes in Kelowna. I've had good luck with both of these sources. I know source was not your question but they are also a good source of information and reply to email.

Failing those two I also like Brian Cullingford at Cullingford Motors in Barrie, Ontario (Moss Dealer). Brian was a British Leyland dealer back in the day and continues to service LBC's as well as many high end euro cars out of that same BL location.
Ken Shaddock

"Well JT, you're are entitiled to your opinion on things"

Gee, thanks for giving me your blessing. This place is starting to sound like the 6 pack forum.
JT White

Yeah Ken I called Octagon and they didn't have an answer. To be honest I would almost consider paying the premium for the pre bent bits if it were close by. I' m not familiar with Len drake as I get most of my needs met by Craig Hunter at hunter classic car parts here on the island or else octagon. I'll drop Ken a line. Otherwise I will try back east. Thanks

Al... if you strike out in BC let me know and I'll check with a few guys in Ontario. I belong to the Toronto Triumph Club which informs me of more Ontario sources than I could have imagined. smokeyssonATgmailDOTcom

BTW, I don't think you'll be dissappointed with Drakes. here's the link to them.

What year is your Six?
Ken Shaddock

Hey Ken,
Got an email from Drakes and they don't have them. Nice guys though. I'll take you up on your offer of maybe sourcing a pre bent fuel line back east. I have a 71 TR. TIA
Al
A Vandergoot

Yeah, Ken. Me too!!

Doug Baker

Al/Doug... here are 4 sources. I know Cullingford's best... Brian Cullingford is a former Brit-Ley dealer and runs a large service shop that's filled with LBCs and high end cars like Jags, Rolls, Rovers, and heck... even the odd Porche shows up to get picked on. He stocks lots of parts to run such a large service operation but if he does not have inventory he orders in from Moss right away. His prices are fair in my option but most of all... he'll know your car and how to help you.

I'll be talking with him later today.

Cheers, Ken

Hi guys... here's another link to hang on to for future. The fee to join this club is $35 annually and they put out a great seasonal magazine to boot called RagTop. You might find some helpful advice through the Marque Coordinators - all volunteers.

BTW, this club hosts one of the largest Brit car shows in North America every September in Bronte Park, Oakville, Ontario... over 1000 Brit cars at every show. It's a blast to show there and a joy to wanderlust around.

Me again... here's an option Al and Doug. I just received this note a few minutes ago...

"Ken, I own British Auto Sport near Hamilton Ontario. We make up TR6 fuel lines for early and late cars and stock the correct brass fittings and compression sleeves. You can contact us at britishautosport@bellnet.ca. Thanks, Fred"
Ken Shaddock

Doug... Fred replied to you but his email was bounced back as undeliverable. Perhaps there's a firewall or filter of sorts at your end. I think he has problems shipping to the USA anyway. I did not know that. Ken
Ken Shaddock

Ken that is great many thanks for getting me the contact info. I will send Fred an email
Al
A Vandergoot

Ken,
I mistakenly sent that note from my office. I'll resend using my private email. That should work. Thanks for alert.
