Hi Dave,
I received my Mopeka sensor and the 6" boat hatch. I'm ready to start the installation but wanted to verify the location you used. You said you installed it "13" from curbside" and "9" back from the rear." The photo you posted seems to show the hatch on the street side of the tank drain elbow rather than on the curbside. On my 1995 the tank drain points to the front of the trailer. When you say "9" back from the rear do you mean 9" from the back of the tank towards the front of the trailer? Would moving it a little more towards the front of the trailer provide a little more clearance from the "lurking PVC pipe"?
