Old cars, especially historic vehicles - Rubber fuel lines - John F

'SWMBO' "What's that dreadful smell of petrol coming from your garage?"

Drip -drip-drip onto the now sodden cardboard which lives under the TR7. Aarrgghh!

Out onto ramps and urgent syphoning into my 4 gallon plastic fuel can (which came overland from Zambia 47yrs ago) until I could remove the rotten 41 year old six inch rubber pipe connecting the tank outlet to the fuel line. Fortunately I had a spare length from a similar sort of repair on another car back in the mists of time which, after immersion in boiling water, softened up sufficiently to fit. The original self-clamping hose clips were still OK.

On googling 'how long do rubber fuel lines last' it appears they should be replaced every ten to fifteen years. Yet another example of the quality and longevity of the components of this much underrated British car.

I had a TR7 - my first new car in 2001. A big step up in quality and performance from Triumph Heralds and Hillmans Imps which preceded it!

After 3 years, owned by me but company funded, I could replace it. The quality engineering and attention to detail also meant that by this time corrosion was clearly bubbing and visible in the seams between sills and rear wings. Sold it for (relative) peanuts!

BTW the recommendation to change rubber fuel pipes is to ensure they are replaced BEFORE they were likely to fail, not when they could almost be guaranteed to fail!

Sounds like you missed an opportunity to install E10 fuel resistant pipe.

Waste not want not. It'll be a good few years before I am forced to use E10, and I suspect the risk of rapid pipe failure is overblown. Indeed, my pipework might fail first.

DIN 73379 Type 3E is the spec for fuels containing ethanol. Also SAE 30R6 comes up as the ethanol compliant spec.

I know BL had little budget for new models but that's pushing it a bit ;-)
