Warning

When installing the sender for your gauge onto the engine, do NOT use any sealant on the threads ( i.e. teflon tape, pipe dope, RTV, etc.). Doing so will prevent the sender from making clean contact with the engine, which will result in either faulty or no operation of the gauge. The senders have a tapered pipe thread to create a seal preventing leakage. This tapered pipe thread also completes the ground to the engine required for proper gauge operation.
