tonka,
We still have the old style aluminum tape system that goes to our Javelina monitor. When it gives up the ghost we are going to the Seelevel system. There are several Foretravel owners that have put these in and report that they have worked great. The only thing is that with the hight of our tanks you will have to get a "probe extension". The system will work without it but will only work on either the top half or bottom half of the tank depending on how the pick up probe is installed. Infact there is a member over on
Foretravel Owner's Forum -- ForeForums that is having one installed on there U-320 this week(1/30-2/5-2012).
It is a do it your self job if you are handy with tools and the instructions that come with the system are good in explaning how to use the origonal wires from the tank location to the dash. Being able to do this saves you from having to pull new wires unless yours are shorted out for some reason.
