Water Tank Sending Guage

Getting help from the IP factory has been key to solving problems with legacy equipment aboard our 1995 IP37 Windragon. We are the third owners, the previous owner John and Kathy Lesniak were based in St Petersburg for 15-years and had great reports of working with Karsten over the years.
Our water sending unit is the original install. The part is made by Rochester Guages. Getting a replacement turned out to require some detective work. Rochester doesn't make direct replacement. Instead they make a generic sender that needs to be custom fit to the tank. Furthermore, they only wholesale senders ...... So
Single senders can be purchased from e-components of Lancaster Virginia. www.ecomponents.net. 804-462-5679. Ask for Tammy.

To our understanding senders for the diesel tank and for the holding tank, if installed, can also be retrofitted to legacy equipment.

How involved is adapting the generic sender to the tank? I have a 1997 IP-37 (#53)so I am hopeful that will work on my tank as well.

thanks for the question. See the photos I have included. The sender is a standard 5-hole with gasket. 240-30 ohms dial.
The generic portion of the sender is the float rod. It comes as about 18 inches and can be shortened to properly fit the tank. You will need a bolt cutter, and long-handled crimpers to shorten then re-crimp the rod end and hold the float on the rod. The sender comes with diagrams and a conversion table to size the fit to various size tanks. The dial needs to be mounted which is fairly straight forward.

I did practice crimping and cutting several times before going down to the final 6-inch length to fit our tank.

Thanks for the pictures but I am a little confused with the third shot. You made the float arm much shorter than what is currently in my tank. How does it reach down to the lower portions of the Tank?
Thanks,
Bob

I have attached the drawings for the Rochester Guage Sender. As you can see, you customize the final rod length to match your tank depth. Our tank sticks at 6-inches deep. So the final cut of the rod was set to get the full length.

The float rod pivots from the empty position (straight down) and rotates 90-degrees to the full position as the fluid level in the tank changes.

Tammy over at e-components is very helpful.

Best to you!
