I want to add another terminal to my fuel sending unit. In a Falcon or mustang it is on the side of the tank and is submerged most of the time. I need a sealed bulkhead fitting.
Something like that one but smaller (that one is 3/8" posts) that is liquid tight.
Ok.... Go!
possible to install on top surface of tank so it's not submerged all the time?
You could use a gland nut bulkhead to run the wire through. Or one of the same gland nuts with a piece of all thread through it and nuts and washers to secure your ring terminals.
This place has gasoline and alcohol resistant gland nuts in a variety of sizes and materials.
