I just purchased an Electric AM Phantom oil pressure gauge at a garage sale for $20. Never out of the box. Brand new. The problem I am having is the sending unit will not fit with my HEI. It hits the dist body. I had to get some piping to bring it up higher because it would not screw into the block because it hit the intake.

Thanks
John

put a hardware store 90 on it, it'll tuck right in under the throttle linkage and clear the firewall no problem.
