Re: Oil pressure sending unit leak, 383 stroker
That hole at the back of the block is 1/8" NPT, so you would need a male 1/8" NPT to a 1/8" male compression fitting to work with the copper or steel line.
The ARP sealant works well for the NPT fitting going into the block IF you take the time to clean it all up beforehand.
Stainless steel braided line using an NPT to -AN fitting would be a better choice here.
