Don H. Posted July 13, 2014 Report Share Posted July 13, 2014 Knowing where it stops only matter if you know where it starts, Roger. Sounds to me like your tank still has almost 3 gallons in it. See how much farther it goes until it's really empty. Take a fuel can with you for the experiment and you probably wouldn't lose a minute before you're back running again.

Peter Cobbold Posted July 13, 2014 Report Share Posted July 13, 2014 Roger Gauge has long been u/s - I use a dowel dipstick marked off in galls. On my 6 I reckon it could be about 2 gallons short using the pump cut-off rather than filling to the bottom of the tube, by eye. 2 gallons being 9 litres, up here.

BlueTR3A-5EKT Posted July 13, 2014 Report Share Posted July 13, 2014 Hi Peter, I've been scratching my head about this one. I know I regularly put in 40Ltrs with the gauge showing empty(ish). But!!! I don;t actually know how much is in the tank. So I need to account for 10ltrs. The nozzle is always fully in the tank - so it isn't quite brimmed Perhaps it is 11 gals (50 ltrs). The obvious answer is that Stuart has spoken - I will listen - I know he is right Roger Yeah, but he failed to mention the stink of fuel in the boot from the leaking sender unit and/or gasket when the tank is brimmed. - An issue my car has so I let the pump cut off at 40 litres. Perhaps I should just get busy and repair the sender gasket..... Cheers Peter W Quote Link to post Share on other sites
North London Mike Posted July 13, 2014 Report Share Posted July 13, 2014 Ah ! 11 gallons Explains my smelly boot, but on a run I always bring the neck and then rock the car 2-3 times to clear the air bubbles in the corner (another half a gallon) .............I'll take the extra range every time Quote Link to post Share on other sites
Swarf Posted July 14, 2014 Report Share Posted July 14, 2014 (edited) Roger, I don't think you are on your own with a petrol tank of 8 or 9 gallons. My TR4 also has a tank of only 9 gallons, as I have never got more than 41 litres in it.....from empty. I had believed the workshop manual 'quoted' capacity of 53.5 litres or 11 3/4 gallons, always believing the fuel gauge simply under read, until driving around lake maggiore last year. Yes I ran out of juice! only 41 litres went in. Now with the benefit of hind sight I must have been running on fumes on many occasions!

North London Mike Posted July 14, 2014 Report Share Posted July 14, 2014 Blimey Chris, that's a sobering thought. I'll dip my tank next time and report back, maybe on the IWE run. So, a batch of smaller repro tanks ?? Did any TR ever have a 9 gallon tank, no? So why does everybody think TR4's are/ should be 11 gallons....... Quote Link to post Share on other sites
graeme Posted July 15, 2014 Report Share Posted July 15, 2014 I believe that the TR4A handbook states that the tank is 113/4 gallons. Cheers Graeme Quote Link to post Share on other sites
Swarf Posted July 15, 2014 Report Share Posted July 15, 2014 Would it be possible for somebody to publish the 11+ gallon TR4 fuel tank dimensions, and then I can start looking for a suitable replacement. Thanks Chris Quote Link to post Share on other sites
North London Mike Posted July 15, 2014 Report Share Posted July 15, 2014 I believe that the TR4A handbook states that the tank is 113/4 gallons. Cheers Graeme Graeme Yes, that's the point ,we all think we have 11-11.5 gallon tanks However, Roger and now Chris have reason to believe their tanks are smaller @ 9 gallons (so where did they come from?)
