Thanks for the response,,,,, wow, this is interesting, 7-10psi for the idiot
light portion of the dual sender?  If that is correct, then I'm okay I
think.   WHen I go to the 15w-40 the light shouldn't come on, since it
"barely" comes on now.   .3 bar, is  4-ish psi, I believe.  If I'm lighting
up "barely at 7-10 psi, then I'm in the normal operation zone!
