When you screw it in it gets 80 in/lbs torque. Most can't get a torque wrench in there so just make it snug. No tape on the threads as it has to ground with the engine case. It is a tapered thread so do not screw it in all the way or it will split your oil pump housing.

Niels, agree with Anticept regarding the remote sender mounting kit. Believe Roger Lee first mentioned this. The sender has a set of contacts which are affected by engine vibration. Remote mounting the sender on the firewall eliminates the harsh environment. This should prolong sender life and I believe it has provided me with a more accurate and consistent oil pressure readout. The kits are sold with all that is needed for installation on the firewall, including fire sleeve for the pressure line. A new ground wire is needed due to the remote not using engine block for ground.

Roger: could you also ground the fitting? I know it's not typical, but i am burning braincells here thinking if that is something that is acceptable, even if unusual.

Hi Anticept,

 

Yes, you can put a ground wire against the sender body and then ground that wire. Same as grounding it on the engine.

 

Oh, the body is grounded? Could just use an additional clamp then for metal to metal!

When you screw the oil pressure sender into the engine it acts as a ground. If you have a Flydat EFIS it uses the two pole sender

 

You could. I have seen it done

I knew the threads were for ground, i wasnt sure about the body. I have already changed over to the piezoelectric oil pressure sender, so i had no idea.
