[DeTomaso] Oil temp sending unit

[Tomas Gunnarsson]

Charlie,

If it's a tapered thread it is supposed to seal without any aid from tape or sealants. If it's a straight thread I'd use a copper washer under the head and keep the threads as clean as possible. However, I have on my car used teflon tape on all my senders for oil and water temperature, pressure sender for oil and warning light for oil pressure and none has failed to work despite this (they are all tapered threads). Unless you go wild with the tape the threads will cut through and make contact somewhere along the threads. I have not tried liquid sealant.

Tomas
