Guess she'* not going down without a fight?
I'm thinking the gasket on the sender assembly may have gotten torn during the install and gotten someplace it wasn't supposed to be. Also looks like it WAS leaking externally.
Not leaking now, also seemed to hold a steady 60lbs for the 15 minutes I had it running. Let it get up to temp, took if for a few loops around the parking lot. Sounds like 99% of the noise is gone, still may not be 100% though.
Tomorrow I will take it out around town a bit, see how it does. It only lasted just over 10 minutes last time, so we will see how this goes.
