I dunno bout dat. A simple T with a short piece of pipe and the oil
pressure switch screws right in (common mod in 1500 Midgets that want
a real oil pressure gauge). The oil pressure switch is probably more
reliable and much less of a pain to diagnose if it goes haywire. I
tend to prefer mechanical "fixes" over electronic wizardry in a
Spridget ;-)
