I recently re-plumbed my Accusump pre-oiler to flow directly into the port on the block previously occupied by the pressure sender. I used all aluminum AN fittings and placed one of those pressure gauge adapters commonly used for fuel pressure gauges (union at both ends). I could not get the gauge to work and figured out it was all that aluminum. To solve the problem I used a stainless hose clamp around the sender with one of those connector tabs. I ran a ground from that to the chassis and it works perfectly.
