Re: [FWDLK] Firewall Grommets

[David Homstad <Dhomstad@CHARTER.NET>]

Greg,

If Gary doesn't have the grommets, a lot of cars used some stuff called dum
dum. It is like tar with the consistency of clay. You can find it at auto
parts stores. It comes as a bead rolled up with a waxed paper. Great for
sealing small holes in the firewall and around body trim fasteners.

It is absolutely necessary that any wires passing through the firewall or
any other sheet metal hole be protected from the sharp edge. Usually a
rubber grommet is used. Dum dum alone is not adequate. Unprotected wires
will eventually wear through the insulation from the vibration and short out
to the sheet metal hole rim. It happened to me once, 3 days after I bought a
car that the previous owner had added a wire through the firewall for an
electric fuel pump. Luckily, the 10 amp toggle switch burnt out first, after
melting the wire insulation off.

I believe Gary Goers makes some if not all of what you need.
