View Full Version : 150psi oil Pressure Gauge and Sender

12-05-2010, 11:58 AM
I just wrapped up installing a VDO 150psi oil pressure gauge and sender and it doesn't seem to be operating correctly. At idle it reads 120psi +/- when I hit the gas it drops down and then springs back up. I've had this happen before and if I remember correctly it was an incorrect sender? Is that the case here? I grabbed both the sender and the gauge from 42 Draft Designs so I'm assuming they sent the right hardware.

What is the approximate oil temperature when it shows this behavior? What oil temperature range have you tried it with?

It's the wrong sender. I forgot I DIDN'T order them both from 42 so I have mismatched hardware. The sender is the wrong OHM's for the gauge, I just ordered a different gauge to match the sender I just installed. It's to cold to switch senders again + a new gauge was cheaper than the new/correct sender. Thanks guys.
