Thanks everyone!
I need to put something on the inside to prevent rust I think.
Any thoughts on what to use, or should I just run it and worry about it in 3 to 5 years when I replace the pump.
The trap is stainless steel but I worry about the plug weld to hold it in place may be a source of rust.
Shelbydogg I don’t know if I want a hole in my trunk...
I know its common on modern cars and I would wish I had one if I ever need to change that pump on the road,
but I don’t know.
