Title: Heat - Exploding Fuel Tanks
Post by: Lizzie Zoom on 29 June 2018, 20:35:20
According to my daughter there is a whole discussion going on about the dangers of car fuel tanks exploding in the heat!

Now I told her, in effect, don't be so daft. How do you think people get on with their vehicles in far hotter climates than ours. Like I have known in Malta with temperatures going past 40c, and what about in other climes were the gauge can go up to, and stay at, 40-45c. I've never known any fuel tank to explode due to heat.

I told her it is the typical British stupidity; temp goes to 30c and everything becomes a major crises out of nothing, like a dusting of snow!  :o ::)

Has anyone else heard of this nonsense? ???

 ;D ;D

It's all over facebook and I've debunked the myth several times this week to the girls in work, they are still only filling half way though  ::)

What next? The government will be telling you to stay indoors, drink plenty of water. There will be a hosepipe ban next, mark my words.

It’s coming from a spoof FB account I think. Something like Indian Traffoc Police. TBF, a lot of their stuff is *just* believable enough to be really funny  ;D

Tell them only half filling a tank leaves the top half full of vapour, and that's the bit that explodes. They need to keep their tank full to the brim.
Then go round your local filling stations and claim your reward.  :)

Yes, that's it, she said it was on Facebook, a pitiful site I will not visit! ;)

Tell her to leave the cap off the fuel tank as the evaporation will help to keep the fuel cooler. ::) ::) ::)

Changing the subject slightly: When I was a kid railway rails weren't very long and were bolted to expansion plates, hence the familiar click-click as the wheel went over each joint. Hot weather was hot weather I don't recall any speed restrictions due to the danger of bucked rails. Now with continuously welded rails and occasional sliced-sliding expansion joints it is now a major risk with daily speed restrictions during the hottest part of the day, such is progress. ???

Already is, in county Fermanagh of all places. The wettest county in the UK.  ::)

I saw that item. How on earth do they manage in countries which have huge temperature variations in a day?

When they stop pissing away 20% of water through leaks, I’ll consider turning the hose pipe off. Until then, I’ve got a house to sell so the lawn needs to be green  ;D

No, as I said I just told her not to be so daft and then explained to her why it was. She has shut up about it now! ;D ;D ;)

They don't use welded rail, still using the old method of expansion joints,as shown to them by there colonial rulers many years ago..

Welded rail is used because it's cheaper, you don't need to have track walkers continually checking the tightness of the joints and associated bolts, Whoops it's not about cost it's all about safety.

Most fuel tanks are made from thick plastic these days, and are located in a position where they don't get any direct sunlight, so air temperature would need to be extremely high before they are affected.
As mentioned, only filling the tank half full is the worst thing you could do if this was going to be a problem, as its the vapour in the empty half of the tank which will go BOOM!

I should scan the picture from the most recent Cobra Club magazine.. at the recent european meet one of the Daytona owners had fuel pouring out of the vent pipe when the steel fuel tank got hot enough for it's contents to expand significantly.. ;D whoops!

Yep, first lesson of Kit car ownership. If you're going to brim the tank when it's hot, do it at the start of a journey, not at the end. ::)
