Good afternoon,
Does anyone know the depth of the tank from the attached photo. The tank is the 140 gallons Auxiliary tank, model number FMT-140-GW. I’m looking to replace the original bad fuel sender unit with a KUS sss/ssl unit and need to know which length to order. I was trying to order the correct one without having to remove the old unit and measure. Mainly to not risk leaving it exposed while I wait on the new sender unit to arrive.
The 150-gallon main tank has a 21" KUS that was installed a few years ago. Any info would be greatly appreciated.
