Get an ohm meter and check it out, hit the intake manifold and the senders
ground, should tell all.
I think most of the systems are pretty tollerent,
but I'll bet your ground is better then you think. I have a substantial
grounding strap to block (bell housing bolt) from the chassis and to the
battery as I have always worried as well. But I think that when you look at
what it might be in the grand tollerance of the system it will not be off that
much. And cleaner connections are always better but sometimes difficult to
have. If your teflon tape is really insulating the sender you will find out as
your gauge won't work all that well depending on the sender type will read
cold or hot right off the bat due to the high resistance of the bad connection
(High ohm's).

Subject: [Tigers] grounding theory
Both the temperature sending unit and
the starter solenoid are shown as
being grounded. The question is how well
do they have to be grounded:-) Will
using teflon tape on the threads of the
sending unit allow the thread to cut
through and still ground the unit?
I
wasn't especially careful in scratching away paint at the base of the
solenoid to ensure good contact nor was I careful in being sure that the
washer
on the bolt was making good contact with bare metal to attach the
solenoid.
How well does this thing have to be grounded?
I guess I am used
to a picky electrical inspector that insisted that the
paint be scraped down
to the bare metal and the metal threaded to ensure a good
ground.
