OK...I'm corn-fused...I get the idea with the water sender but... I don't get where to go with the oil line sender....the reason I'm not using electric is that the wire loom needs more work and we will attack that when we have the orginal guages rebuilt...sorry about the dumb questions but the truck is 150 miles from where I live so I have to do most of the question work by memory and I just can't remember where the oil hook up would be...THANKS!
