Fuel filler tube

[rfurzer]

Gday

I'm slowly progressing through my GS to station-wagon conversion. I have most of the loose ends sorted (or a plan to sort them).

I haven't pulled the GS filler apart (i'm keeping the vehicle in one piece until the great transformation). Peering down the throat, there seems to be an immediate reduction to 2" pipe BUT looking behind the driver's seat and up the wheel arch there is 3" OD pipe. Is it double- walled? if so why?

Thanks

I've pulled mine apart.

The filler tube is double walled - there is an inner 50mm ID tube and an outer (approx) 75mm with a welded-on flange to go through the bulkhead. There is a nasty rust-filled cavity between them - not a design masterpiece.

Hi rfurzer,

Do you have a chain that attaches your filler cap to the filler neck? I have on my RFSV but not sure if this is the same set up across the different variants.

If so are you able to access the chain that attaches the filler cap to the filler tube easily once you pull the filler out? The chain on my filler cap has come off where it attached to the filler neck. I haven't had time to really investigate it yet but thought I would pose the question since you have yours apart.

Any info would be appreciated.

Regards Warrick.

I think there is a coat-hanger shaped wire in the neck that the chain attaches to, and it would slip down if the chain came adrift at either end.
County fuel caps also have a chain but that is attached to the filler neck extension.
