Fuel filler pipe??

Outwest34au · #1 (**permalink**) 12-18-2011, 11:59 PM

I have made a fibreglass recess for my filler cap (RHS rear gaurd), got some ally pipe bead rolled to weld into the tank for a filler but thought I better check before I went any further.
I am planning on using bead rolled exhaust tube for the actual connecting pipe but due to the placement of the cap it will be exposed in the wheel well.
In the event of a tyre failure it could be open to damage from debris. Is this fittment allowable? or can it have to have a cover skin to protect it?

I have seen others that come straight into the boot and are not exposed in the wheel well and now I am wondering if I have got it wrong?

Any advice or criticism welcomed.

I have seen many others which run through the wheel well, engineers don't seem to mind.

Excellent. Thanks Ben.

I've got an RMC and the filler pipe is exposed inside the RH guard..My engineer suggested that I build a 'double' tube to protect it from a tyre failure. I have fitted an LPG system and the double tube is mandatory. These were 2002 rules and many production utes etc just use a single pipe and lots of rubber connections...it seems that the choice is up to you and your common sense.

Thanks Rob, I have some ideas on how to minimise the risk of damage and will look at them when I get a day off.
The double tube on LPG systems is to help vent the gas away from an enclosed or passenger compartment in the event of a leak or rupture. If yours was in a steel tube that was protection maximus. Looking at the video I have of several XA's being torched to test the venting methods used back then (70 - 80) you would reckon a government department had designed them with the grim reaper as chair person and bankroller combined.

Why don't you try and make up a fibreglass outer that could be attached around the pipe and affixed to the wheel well skin?

I have assumed the pipe runs close to the side of the wheel well for this to be possible though.

Working glass around some form of mould would be very easy to do and once you had an initial shape you could build it up for strength.

I'm thinking about the same idea but inside the boot as an odour protection method to help avoid a boot full of fuel fumes.
