oil pressure gauge ran to the blower

[DavidT]

my sho had an electric oil pressure gauge installed when I bought it. It is ran to the blower and not the stock sending unit above the oil pan. Will this give me inaccurate readings?

Is it the feed or return line? Assuming its the feed line, it should be ok, but possibly a little on the low side. The return line probably wouldn't even make the gauge twitch.
