Eric,
I've been piecing together the responses I've had... It seems that the .5
Bar sender would cause the idiot light (& buzzer) to come on sooner (around
7psi) than the stock .3 Bar sender (around 4 psi). It that is so, then I
don't understand your comment:

"That's enough to turn off any idiot light in any engine."

Can you please enlighten me?
(seems like the light coming on at 7psi rather than 4 psi would give you
more warning of low oil pressure problems and thus be a better warning
device... assuming it's not normal for the engin to run at 7psi which would
cause the light to be a pain in the butt.)

Thanks
Bill
