87 R30 7.4L Oil pressure gauge sender

[Classman]

Thanks for the information, much appreciated.
My leaking sender is a single wire unit for the gauge only. I have the multi wire sensor like yours, on the same branch, at the front of the block near the oil pan rail. It doesn't leak.
Leaking unit is the can type with the blade terminal straight off the end.
Trying to find out if any particular brand is working ok in the same situation.
