I don't have the original post about the vette tank.  Was it over flowing
after a run with a freshly topped off tank?

Many/all FI cars have a large air space in the tank, even when filled up.
Take a look at a FI tank, you will see the fill pipe and vent pipe extended
into the tank.  The end of the pipes are below the top of the tank limiting
the fuel fill by traping a air pocket.

>From what I remember, the vette ( 72? ) gas fill is directly on the top of the
tank.  Adding a 2"-3" sleeve inside the fill neck should limit the fuel
capacity.


Remember the early eightys when the Ford ambulances spilled fuel and burst
into flames?  This was caused by high under body temps, not enough expansion
space in the tank and the tendency for over filling by the ambulance drivers.
