Fuel tank, fuel filler pipe and fuel cap - talk to me please

11 Oct 2012, 9:54am
Well I will only need a short cuff of rubber piping. basically to join the metal filler neck from the tank to the metal filler funnel from the cap and to allow for any misalignment or non-matching angles.

The cardboard collar in this photo below is the inner from one 2" tape and is about the right length hopefully. I will check with the hose supplier that what I get is fuel safe.

Thanks

I picked up an MX5 tank plus filler neck complete with cuffs for £10 plus a trip to Reading. OK, I'll need to introduce a new mount, but it sits low and flat behind the bulkhead. It may well be safer in an accident (not that bothered about that as I like the idea of leaving this earth in a massive fire ball) and it lowers the CoG a bit.

My fuel filler cap is likely to be the first think anyone will hit in a shunt from behind!

Is it wrong to leave this earth in a massive fire ball?

I always assumed that is how I would end up.

I'm with you on that one - I also find it vaguely amusing to see people who ride motorcycles talking about crash safety. Although, in an accident on a bike I suppose the fuel tank is protected from damage by the pink squashy thing laying on top of it and holding the handlebars. :flame:

Not many Sammio builders are going to go to heaven, so you may as well bring on the heat straight away.

Fuel leaks and spills are a risk to all road users.

Putting a little bit of effort and thought into selecting fuel compatible materials and mounting the tank and filler neck so that a simple shunt doesn't result in a significant release of fuel isn't much to ask is it?

I missed the smiley face off my comment - not suggesting designing cars to burst into flames is a good idea.

I was always dubious about having the fuel filler hanging over the rear bumper.

The silver metal you can see below the tank filler neck is the back of the chassis with the tank itself sat between the main front to rear chassis rails.

The fuel filler cap will be mounted to the bodywork.

There will be a (very) short length of fuel pipe connecting the two.

in the event of a crash, the body work is likely to break first leaving the fuel tank, fuel pipe and fuel filler intact.

hopefully ;-)
