D1070 Posted April 7, 2011 Report Share Posted April 7, 2011 Hi All, I have never been very happy with the 5s petrol tank capacity,-it brims at around 40 litres,or 8 gallons in old money, with 3 hungry webers to feed it doesnt give much more range than 200 miles. Having completed a number of continental trips i have learnt to always carry a spare 5lts if things get a little desperate,-and they hav,- on more than one occasion. Tank capacity has loomed larger in my mind in recent weeks because i have had confirmation of my entry to do the 10CR in September,- essentially completeing a round trip of Alpine Europe in 3 days with fellow Triumph enthusiasts,- CT organise it and the mileage is likely to be in excess of 2000. My question is :,are larger petrol tanks available and 2, what was the original capacity of a TR5 petrol tank?, cheers, Laurence Quote Link to post Share on other sites
RobinTR6 Posted April 7, 2011 Report Share Posted April 7, 2011 I think you can get slightly larger tanks, the 'alloy' ones from specialists seem to squeeze a bit more in. Dont have any links but they are readily found. Youve confused me as I was always under the impression (from various handbooks etc) that the TR5/6 tank held 55 litres....so your 40 throws me completley...lets see what others think.

carld Posted April 7, 2011 Report Share Posted April 7, 2011 Hi Laurence From memory the original tank holds 11 gallons/51 litres, I have seen ali tanks that add an extra 6 litres or so to the capacity. I guess that if you are brimming at 40 litres, the gauge isnt all that accurate, now theres a surprise. Cheers Carl Quote Link to post Share on other sites

Laurence, I have one from http://andywiltshire.com/web%20site%20tank%20page.htm . Not far from you. Stan Edited April 7, 2011 by smizgals Quote Link to post Share on other sites
D1070 Posted April 7, 2011 Author Report Share Posted April 7, 2011 I am now beginning to wonder what tank i actually have in the 5!. It definately takes no more than 40 lts, which would seem to be 15lts short of a standard 5s tank capacity. Thankyou Stan for the link, cheers, Laurence Quote Link to post Share on other sites
Guest ntc Posted April 7, 2011 Report Share Posted April 7, 2011 (edited) Laurence Something does not add up here?? I run webers as you know and I can get 275m + out of 1 tank but not on the track Edited April 7, 2011 by ntc Quote Link to post Share on other sites
D1070 Posted April 7, 2011 Author Report Share Posted April 7, 2011 Neil, Seems that way, -i have lived with 40l capacity for 4 years, but with the 10CR event in five months, now might be a good time to increase its modest capacity, cheers, Laurence Quote Link to post Share on other sites
Tom Fremont Posted April 7, 2011 Report Share Posted April 7, 2011 Laurence Something does not add up here?? I run webers as you know and I can get 275m + out of 1 tank but not on the track Same here ( though I don't empty mine completely - that's what I'd get if I left 1/2 gal in ). The TR250 factory owner's manual says 11-1/4 IMP Gal / 51 liters / 13.5 US gal. Could there be some anti-slosh mod in yours which ate up capacity? Quote Link to post Share on other sites

Thankyou Stan for the link, cheers, Laurence Laurence, If, like my old tank from a TR6, you have baffles then you may be suffering from a blocked outlet from the anti-surge reservoir. Something I discovered when not being able to completely empty it through the outlet. And explained why for years I was puzzled that I was unable to fully re-fuel with the expected amount. I am told the capacity of fuel tanks varied. Around 48 litres, 10.5 Imperial Gallons, is realistic. Wrongly using 12 US Gallons (1.2 = 1 Imperial Gallon) for conversion will give a capacity of 55 litres. Stan Quote Link to post Share on other sites
