Greg - absolutely, definitely (and
legally), do not pipe the overflow outside (ie dumping to the ground) unless you want to be on the 6 0'clock news
There are a number of issues here, not least of which is your own safety.
Here are several pictures that should indicate what sort of breathing and provision for overflow that you need....
Firstly, a picture showing the general arrangement of the pipes/hoses, clearly showing the overflow hose connected just below the fuel filler.....
Next one shows more clearly the fuel tank breather hose (the small diameter hose that loops up quite high) as well as the fuel return (to the tank, it's the larger diameter hose)....
Lastly, this one shows the plumbing underneath. You can see the overflow hose (the larger hose) connected so that the fuel overflow returns directly to the tank. It also shows the breather hose (the smaller hose) which goes forward to the charcoal canister mounted somewhere near the engine.
Also extremely important is to install an earth strap to electrically connect the fuel filler (remember it's metal, so it's electrically conductive!!) to the chassis (earth).
That could save you and your car from catching fire.
I hope that helps a little.
Cheers!
